The muon is a subatomic particle that resembles an electron but is 200 times heavier. It interacts with nuclei through the weak force, one of the four fundamental forces in the Universe. When a muon ...

The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds ...

A pictorial rendition of the proton-proton fusion chain in the Sun. The fusion of a proton with beryllium-7 produces a boron-8 nucleus that later decays emitting neutrinos that can be detected on ...
