Michael Riordan surveys the extraordinary year of 1964, which saw the birth of the quark model, the invention of the Higgs ...

But amid oodles of particle collisions, statistical fluctuations are bound to arise, so a 1-in-1,000 deviation doesn’t count as hard proof of a break with the standard model.

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 ...

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

Researchers from the University of Rochester have helped measure the elusive top quark with unparalleled precision, and the surprising results affect everything from the Higgs boson, nicknamed the ...

For the first time, particle physicists have observed the simultaneous production of a photon and a top quark. The milestone was achieved by the ATLAS collaboration, which operates a giant detector at ...

The LHCb experiment at CERN's Large Hadron Collider has reported the observation of Xicc++ -- a new particle containing two charm quarks and one up quark. The existence of this particle from the ...

A quark like no other Date: January 18, 2017 Source: University of Iowa Summary: A physicist is at the forefront of the search to confirm the existence of a particle believed to give mass to all ...

Jonathan L Rosner, a distinguished theoretical physicist and professor emeritus at the University of Chicago, passed away on ...

He decided to see if there were a better way to calculate the mass of the top quark from the measurements already collected at Fermilab’s particle accelerator.
