New York, March 3 : A team of US researchers has detected a new form of elementary particle called the "four-flavoured" tetraquark that can affect scientists' understanding of "quark matter" -- the hot, dense material that existed moments after the Big Bang and may still exist in the super-dense interior of neutron stars.
For most of the history of quarks, it's seemed that all particles were made of either a quark and an antiquark or three quarks,
"This new particle is unique -- a strange, charged beauty. It's the birth of a new paradigm. Particles made of four quarks -- specifically, two quarks and two antiquarks -- is a big change in our view of elementary particles," explained ," said Indiana University physicist Daria Zieminska.
Zieminska is a lead member of the team responsible for the particle's detection by the DZero Collaboration at the US Department of Energy's Fermi National Laboratory.
Quarks are the building blocks that form subatomic particles, the most familiar of which are protons and neutrons - each composed of three quarks.
There are six types, or "flavours," of quarks: up, down, strange, charm, bottom and top. Each of these also has an antimatter counterpart.
A tetraquark is a group of four quarks, the first evidence for which was recorded by scientists on the Belle experiment in Japan in 2008. But the new tetraquark is the first quark quartet to contain four different quark flavors: up, down, strange and bottom.
The DZero experiment is also responsible for other fundamental physics discoveries, including the first observation, with the Collider-Detector at Fermilab experiment, of the elusive Higgs boson particle decaying into bottom quarks.
The discovery of the tetraquark - reported in the journal Physics Review Letters - also comes on the heels of the first observation of a pentaquark -- a five-quark particle -- announced last year by CERN's LHCb experiment at the Large Hadron Collider.
Zieminska is also a member of the ATLAS Experiment at CERN, the European Organisation for Nuclear Research.
Should be called the Trumpetron
This will just keep on going ...what makes up the elements of these things?....As time goes on the more we discover only shows how little we actually know...What an amazing life and its components so complex...
It’s incomprehensible to me how anyone could think this all just happens randomly.
This will just keep on going ...what makes up the elements of these things?
The fingerprints of GOD, me thinks.
Affect? Or effect?
"Affect" implies a negative change, i.e.: cold weather affects my health.
"Affect" can also imply a moving emotional experience, i.e.: that music affects me deeply.
Neither seems to apply here.
"Effect" is a simple, straight-forward change, i.e.: "tetraquarks can effect scientists understanding of 'quark matter' ".
But "effect" is hardly the best choice of words.
Other words like, "change", "modify" or "increase" are clearer, less nebulous.

Amazing. But then this was predicted years ago by the Pointer Sisters: “I’m just burning , doing the neutron dance.”
And followed up by that other brilliant physicist Elmer Fudd in his profound work, “Fiii-wah”
I can make up stuff too. It looks to me like they’re reaching.
Yes it is!
I can vouch for it, there are four quark particles all around where I live. We have had heavy rains recently and after the rain you can hear them going Quark...Quark...Quark...Quark, the cat tries to hunt them down but never seems to catch one. Sometimes there are so many quarking at once that it sounds like a constant buzz.
My dad feels like high-energy particle physics today is akin to ramming sixteen vehicles together at near supersonic speeds, then looking at the broken pieces and trying to figure out how the screws, nuts and sparkplugs that fell out on the highway make the truck work.
But they don’t know if it was two trucks, two 737’s, or two VW bugs that actually collided each time.
I get it!
My TEA (Theory Explaining All) is that someone's Universe Kit exploded. And yet, in some other dimension, kids are still given Universe Kits. They're said to be educational.
That is not correct.
Affect (v) 1: have an effect on; make a difference to:
Well this is a load off!! I’m sure the practically applied advances in technology will be rolling in any week now.
LOL!
“...two quarks and two antiquarks...”
A Quarktette.
