LHCb discovers three new exotic particles (Large Hadron Collider)

Only time and more studies of exotic hadrons will tell if these particles are one, the other or both.

LOL...No doubt we will also need ever-bigger versions of colliders to keep finding ever-smaller elementary particles. This is beginning to look like a "science fair" funded by a pocket with a deep space. And I blame this guy for starting the whole thing.

They were 26 at the time of that photo. I think part of it is bad 1970s TV studio makeup. “Quark” wasn’t exactly a high-budget show for showcasing the studio’s best talent.

Thanks GOPJ.

Thanks rdl6989!

I don’t think God cares that much of us fumbling in the weeds.

Have any of these Colliders ever paid for themselves?

"The first kind, observed in an analysis of “decays” of negatively charged B mesons, is a pentaquark made up of a charm quark and a charm antiquark and an up, a down and a strange quark. It is the first pentaquark found to contain a strange quark. The finding has a whopping statistical significance of 15 standard deviations, far beyond the 5 standard deviations that are required to claim the observation of a particle in particle physics.

It's difficult to tell whether this is a scientific journal or a Dr. Seuss story.

"Most of the exotic hadrons discovered in the past two decades are tetraquarks or pentaquarks containing a charm quark and a charm antiquark, with the remaining two or three quarks being an up, down or strange quark or their antiquarks. But in the past two years, LHCb has discovered different kinds of exotic hadrons. Two years ago, the collaboration discovered a tetraquark made up of two charm quarks and two charm antiquarks, and two “open-charm” tetraquarks consisting of a charm antiquark, an up quark, a down quark and a strange antiquark. And last year it found the first-ever instance of a “double open-charm” tetraquark with two charm quarks and an up and a down antiquark. Open charm means that the particle contains a charm quark without an equivalent antiquark."

Breakfast time onomastics.

Well...I suppose they will be assigning them genders soon too. (Happy that we have not been sucked into an alternative dimension, at least so far...)

I honestly can’t make heads or tails from it.

What I worry about is scientists who think they know what they are doing making a bad mistake. Or, scientists who are so driven to push the boundries that they do not care about putting other people at risk. Or, some hidden agenda behind the scientific facade with bad consequences. (Q.v. CS Lewis’ “That Hideous Strength”.)

I am glad we have made it through today.
