    Nobel prize-winning physicist Peter Higgs, who proposed the existence of the so-called "God particle" that helped explain how matter formed after the Big Bang, has died at age 94, the University of Edinburgh said Tuesday. The university, where Higgs was emeritus professor, said he died Monday following a short illness. Higgs predicted the existence of a new particle, which came to be known as the Higgs boson, in 1964. He theorized that there must be a sub-atomic particle of certain dimension that would explain how other particles—and therefore all the stars and planets in the universe—acquired mass. Without something like...

    The world’s largest and most powerful particle accelerator is set smash protons together on April 8 to search for invisible particles secretly powering our universe. Theories have suggested there are 17 different particle groups and the European Organization for Nuclear Research, better known as CERN, confirmed the existence of one using its Large Hadron Collider (LHC) in 2012. Now, the team has restarted the LHC with hopes of unraveling more mysteries of the universe - specifically dark matter. Scientists began preliminary tests by sending billions of protons around the LHC's ring of superconducting magnets to boost their energy and ensure...
  • Evidence of Higgs boson contributions to the production of Z boson pairs at high energies

    Since the 1970s, physicists have predicted that when pairs of heavy vector bosons Z or W are produced, typical restrictions at high energies would be violated, unless a Higgs boson was contributing to the production of these pairs. Over the past ten years, theoretical physics calculations showed that the occurrence of these Higgs boson contributions at high energies should be measurable using existing data collected by the LHC. As part of their recent study, the CMS collaboration analyzed some of the data collected between 2015 and 2018, as part of the second data collection run of the LHC. They specifically...

    Europe’s preeminent particle-physics organization will need global help to fund the project, which is expected to cost at least €21 billion and would be a follow-up to the lab’s famed Large Hadron Collider. The new machine would collide electrons with their antimatter partners, positrons, by the middle of the century. The design—to be built in an underground tunnel near CERN’s location in Geneva, Switzerland—will enable physicists to study the properties of the Higgs boson and, later, to host an even more powerful machine that will collide protons well into the second half of the century. The approval is not yet...

    Geneva, 28 August 2018. The ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) has – at long last – observed the Higgs boson decaying into a pair of bottom (b) quarks. This elusive interaction is predicted to make up almost 60% of the Higgs boson decays and is thus primarily responsible for the Higgs natural width. Yet it took over six years after the 2012 discovery of the Higgs boson to accomplish this observation. “ATLAS is proud to announce the observation of this important and challenging Higgs boson decay," says Karl Jakobs, ATLAS Spokesperson. “While the result is certainly a...

    Today, workers at the world’s largest atom smasher are breaking ground on a performance-enhancing upgrade that will allow scientists to conduct even bigger and better physics experiments. The upgrade will turn the Large Hadron Collider in Geneva, Switzerland into the High-Luminosity Large Hadron Collider (HL-LHC). The upgrade will allow the machine to collide even more particles, potentially helping physicists see new stuff. “The HL-LHC will enable us to do many things, opening many unexplored areas of research,” Rebeca Gonzalez Suarez, a postdoc research associate at CERN, told Gizmodo in an email. The Large Hadron Collider is essentially two 16-mile-round rings...

    The Higgs field is like an endless ocean through which all matter swims. Some particles are like sponges and sop up mass as they lumber along, while others are as sprightly as tiny minnows and dart right through. … "We know that the Higgs interacts with massive force-carrying particles, like the W boson, because that's how we originally discovered it," said scientist Patty McBride ... "Now we're trying to understand its relationship with fermions." Fermions are particles that click together to form the invisible scaffolding inside atoms. Bosons, on the other hand, are the physical manifestation of forces and perform...

    [Physics] has a reputation for being extremely complicated, but sometimes the simplest questions that lead to truly profound and obvious insights. When Einstein asked himself, “What would happen if you could ride on a beam of light?” for example, the answer led him to the Special Theory of Relativity.  He concluded that the speed of light was constant. Taylor Momsen was touring with her band The Pretty Reckless and they stopped on the side of the road so some of the band members could relieve themselves.  One of the band members, the drummer Jonathan Burger, was the nephew of  physicist...
  • The Higgs Boson's Twin Could Reveal Our Universe’s Dark Sector

    10/02/2017 4:38:54 PM PDT · by BenLurkin · 8 replies
    The problem in the Standard Model lies in the fact that the measured mass of the Higgs is about 100 million billion times smaller than what quantum mechanics suggests it should be. From the standpoint of the Standard Model, this can be true only as a result of an extremely unlikely coincidence involving the values of some of the universe’s fundamental building blocks. ....Physicists call this situation the “hierarchy problem” and see it as evidence that the Standard Model is only an approximation of a more comprehensive theory that would explain the Higgs mass “naturally”—as the result of some mechanism...

    Eight months after raising hopes that they may have found an intriguing new particle that cannot be explained by the existing main physics theory, disappointed scientists are saying: Never mind. It was just a statistical burp, not a breakthrough, researchers reported Friday. […] Early unconfirmed readings of a new particle in December by physicists at the center, called CERN, set the physics world abuzz. Scientists there had discovered the Higgs boson or “God particle” in 2012, and two new readings from the Large Hadron Collider made it seem as though they may had found a revolutionary new particle. …

    Ten days after the three-year anniversary of CERN’s discovery of the Higgs boson, researchers on the LHCb experiment at CERN have announced that another discovery has been made: They have found a new exotic class of particles. The team has submitted their findings to the journal Physical Review Letters for reviewal. These particles are called “pentaquarks,” and they offer some interesting insights regarding the nature of, well, nature. Typically, we find that composite particles consist of three quarks. The proton, for example, is composed of three valence quarks: Two up quarks and a down quark. But in 1964, American physicist...

    Dark matter has long remained one of the greatest unsolved mysteries of the universe. While its presence can be inferred from the gravitational pull it exerts on visible matter, the fact that it does not emit or absorb any radiation makes it next to impossible to detect. ... The new model put forward by a team headed by Christoffer Petersson, a theoretical particle physicist from Chalmers University of Technology in Sweden, suggests that the Higgs boson, discovered by the LHC in 2012, might be responsible for the birth of dark matter particles.

    At the Large Hadron Collider (LHC) in Europe, faster is better. Faster means more powerful particle collisions and looking deeper into the makeup of matter. However, other researchers are proclaiming not so fast. LHC may not have discovered the Higgs Boson, the boson that imparts mass to everything, the god particle as some have called it. While the Higgs Boson discovery in 2012 culminated with the awarding in December 2013 of the Nobel Prize to Peter Higgs and François Englert, a team of researchers has raised these doubts about the Higgs Boson in their paper published in the journal Physical...

    Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone. Many calculations indicate that the particle discovered last year in the CERN particle accelerator was indeed the famous Higgs particle. Physicists agree that the CERN experiments did find a new particle that had never been seen before, but according to an international research team, there is no conclusive evidence that the particle was indeed the Higgs particle... "The CERN data is generally taken as evidence that the...

    Particle physicists at the European Organization for Nuclear Research announced 2 years ago they had discovered the Higgs particle, considered the foundation particle in the Standard Model of Particle physics, and a Nobel Prize was awarded to Peter Higgs and Francois Englert for their work on the theory of the Higgs boson. Now, though, researchers at the University of Southern Denmark's Center for Cosmology and Particle Physics Phenomenology suggest that while the CERN scientists did discover a unique new particle, there's no conclusive evidence of it being the Higgs boson. The Higgs could explain data obtained by CERN scientists using...

    Wikimedia Commons, ULBPhysics laureates. Peter Higgs (left) and François Englert. The most eagerly anticipated and potentially controversial Nobel Prize for physics in many years was awarded today—following a nail-biting hourlong delay—exactly according to the expected script: The winners are Peter Higgs and his fellow theorist François Englert for, essentially, predicting the Higgs boson. The winners were much heralded following last year’s discovery of the Higgs by physicists at the CERN particle physics lab near Geneva, Switzerland, using its Large Hadron Collider (LHC).That finding put in place the last piece of the puzzle to complete the standard model of fundamental particles...

    Last year’s discovery of the Higgs boson was thought to answer a number of questions regarding how particles derive their mass. Now, however, it seems the discovery of the elusive particle is raising more questions than answers. Physicists at King’s College in London now say they have recreated conditions for the Big Bang now with the information from the discovery of the Higgs boson, and they report that the universe should have expanded too quickly and collapsed.

    Scientists hoping to puzzle out how the Universe began will find a long-sought theoretical particle — or rule out that it exists — by the end of 2012, the director of the world's largest atom smasher predicted Monday. Rolf Heuer, director of the European particle physics laboratory near Geneva, said his confidence was based on the latest findings from the $10 billion proton collider under the Swiss-French border. "I would say we can settle the question, the Shakespearean question — 'to be or not to be' — end of next year," he told reporters at a major physics conference in...
