The first speaker was Billy Loo from Stanford University, who argued the case for photon-based FLASH. Loo is part of a multidisciplinary research group that’s developing a range of novel linear ...

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly understood. These massless particles mediate the strong nuclear force, ...

OLYMPUS experiment sheds light on structure of protons Seven-year study indicates two photons, not one, are exchanged in electron-proton interactions.

When you fire an electron lightly at a proton, it usually delivers a photon to one of the quarks and glances off. But in fewer than one in a billion events, something special happens. The incoming ...

Last, the method used in the latest set of experiments, involves muonic hydrogen, which is a proton with a muon, rather than an electron, orbiting around it. Like electrons, muons are negatively ...

Ji’s and Polyakov’s calculations showed that if experimentalists could collect the resulting electron, proton and photon, they could infer from the energies and momentums of these particles what ...

In February, the proton, photon, electron and neutron threw their hats into the ring for the Subatomic Smackdown. This month, they sparred at the open house for the National High Magnetic Field ...

Previous experiments at Jefferson Lab used a photon beam to measure J/ψ production of a solitary proton in the GlueX detector. To produce J/ψ, which is a heavy particle, the energy of the photon ...

When a high-energy photon strikes a proton, secondary particles diverge in a way that indicates that the inside of the proton is maximally entangled. An international team of physicists with the ...

In this study, the research team discovered that these photon sensors could potentially also function as highly accurate particle detectors, specifically for high-energy protons used as ...
