It's a twenty-year-old question: how much do the constituent quarks and gluons contribute to the spin of a nucleon? New results from the COMPASS experiment add to the picture. Naively, the proton ...
I took Proton Mail for a spin and came away impressed. Here, I'll discuss specific features that make me love Proton Mail, highlighting what sets it apart from Gmail. If you are curious about a ...
Physicists turn to supercomputers to help build a 3D picture of the structures of protons and neutrons. A team of scientists has made exciting advances in mapping the internal components of hadrons. T ...
Protons and neutrons consist of distinct combinations of up and down quarks ... The team believes their findings could help address the longstanding “spin crisis“. This is the large body of ...
