Neutrinos are notoriously antisocial, nearly always slipping past atoms of matter without so much as a “how do you do.” But new research indicates that on the rare occasion a neutrino and an atomic ...

The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured ...

Protons in neutron-rich nuclei have a higher average energy than previously thought, according to a new analysis of electron scattering data that was first collected in 2004. The research appears to ...

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 ...

Neutrinos are noted for being extremely reluctant to interact with other matter. While it’s possible to build hardware that will detect them, these detectors tend to be enormous in order to provide ...

Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom. A new study comes closer than ever to ...

Thousands of meters underground, in the chthonic depths of Earth's crust, scientists have at long last caught solar neutrinos in the act of transforming carbon-13 into nitrogen-13. It's the first time ...

WE have generalized a theory put forward by Yukawa 1 showing that nuclear forces can be explained by assuming the existence of new particles of mass about two hundred times that of the electron. Our ...

Neutrino detectors, like the one used in the BOREXINO collaboration here, generally have an enormous tank that serves as the target for the experiment, where a neutrino interaction will produce ...

Physicists make a lot of statements about stuff they hope will happen, but might not happen in their lifetimes. One physicist, for example, thought that in certain cases, the incredibly common but ...
