A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The calculations ...

Protons and neutrons, which are collectively known as nucleons, are the building blocks of atomic nuclei and account for more than 99% of the visible matter in the Universe. They are not themselves ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

UPTON, NY—A collaboration of nuclear theorists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Argonne National Laboratory, Temple University, Adam Mickiewicz University of ...

If you buy something using links in our stories, we may earn a commission. Learn more. It often goes unmentioned that protons, the positively charged matter particles at the center of atoms, are part ...

The LHCb collaboration is far less famous than CMS or ATLAS, but the particles and antiparticles they produce, containing charm and bottom quarks, holds new physics hints that the other detectors ...

In late 2023, Wojciech Brylinski was analyzing data from the NA61/SHINE collaboration at CERN for his thesis when he noticed an unexpected anomaly—a strikingly large imbalance between charged and ...
