This frame from "Visualizing the Nucleus" shows animations of four different nuclei, with their protons and neutrons, quarks and gluons visible. NEWPORT NEWS, VA – There has never been a better time ...

The horizontal axis represents the proton scattering angle and the vertical axis represents the ease with which protons are scattered. C-type and S-type are theoretical values assuming cluster and ...

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 ...

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 ...

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 ...
