Scientists at CERN have observed an unexpected phenomenon within the world’s largest particle accelerator that suggests that ...
An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider ...
It includes six flavours of quark, their six antimatter counterparts and several other elementary particles, including electrons and photons. The standard model also includes rules for how quarks ...
To find the particle, the team behind the D0 detector reasoned that the particle would decay into a pair of two-quark particles, a pion and a B-meson. The B-meson, in turn, would decay into two ...
Both teams were looking at a particle called Y(4260) that had been discovered in 2005 but whose nature has mystified researchers since. By smashing together electrons and their antiparticle ...
The new particle mass will allow scientists to test the mathematics of quantum connections among the top quark, the Higgs particle the particle detected by the LHC in 2012, which explains how ...
On the other hand, Eichten notes, the large mass of the new particle closely matches that expected if two quark-antiquark D-mesons got hitched. Science News sponsorship position.
Several recent findings have suggested particles with greater quark numbers (SN: 12/13/03, p. 381: Available to subscribers at Hints emerge of a four-quark particle), but other data haven’t ...
A new type of particle may have shown up independently at two particle accelerators, physicists say. The particle, made of four quarks (the ingredients of protons and neutrons), appears to ...
What the X particle looks like still isn't clear, ... To detect an X particle, make some quark-gluon plasma. By Rahul Rao. Published Jan 28, 2022 4:00 PM EST.
Over the past decade, however, particle-accelerator projects all over the world have gathered some evidence that a few different kinds of four-quark particles might exist. Physicists give such ...
Scientists have determined the mass of the heaviest elementary particle, the top quark. The measurement was made using the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, and the ...
