S cientists can determine the mass of subatomic particles that are built from quarks by looking at the particles' energy and momentum in four-dimensional spacetime. One of the quantities that ...
Dirac fermions have mass and aren’t their own anti-particles ... in table-top experiments — whereas to discover subatomic particles we often need huge colliders,” Agarwala said.
Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...
