CHAMPAIGN, Ill. — An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton. Quarks are subatomic ...

Proton probe: the MINERvA experiment at Fermilab has been used to study the structure of the proton using neutrinos. (Courtesy: Reidar Hahn/Fermilab) Following a bold suggestion from a postdoc ...

NEWPORT NEWS, VA – Nuclear physicists have confirmed that the current description of proton structure isn’t all smooth sailing. A new precision measurement of the proton’s electric polarizability ...

Physicists used MINERvA, a Fermilab neutrino experiment, to measure the proton’s size and structure using a neutrino-scattering technique. For the first time, particle physicists have been able to ...

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as ...

Scientists working on CERN’s ALICE experiment have reported the first observation of a distinctive flow pattern among quarks ...

Protons sit in the nuclei of all atoms, but they are not fundamental particles: They are made of three quarks held together by the strong nuclear force. The strength of this interaction is actually ...

Discovered in 1912, cosmic rays have been studied extensively and our current understanding of them is compiled into what is called the Standard Model. Recently, this understanding has been challenged ...

The proton is stretchier than we thought, according to new measurements. But physicists are divided on whether this anomaly will persist in future measurements or if our fundamental understanding of ...
