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 ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

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 ...

A new precision measurement of the proton's electric polarizability has confirmed an unexplained bump in the data. The proton's electric polarizability shows how susceptible the proton is to ...

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 ...

Physicists working with molybdenum-84, a nucleus containing exactly 42 protons and 42 neutrons, have found that this seemingly balanced atom defies one of nuclear physics’ longest-standing ...

Researchers at the University of Waterloo have produced experimental evidence that quantum-level effects can alter the ...

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 ...

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 ...
