The structure of the proton is under the microscope at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia, where a series of ...

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 ...

Nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's ...

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 ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

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 ...

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 ...

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 ...

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 ...
