Nuclear theorists uncover the mass distribution within the pion and the proton through groundbreaking first-principle ...

Hairs on the toes of Mexican free-tailed bats light up under ultraviolet light, but the reason is unknown, Jason Bittel reported in “Mexican free-tailed bats’ ...

Seventy-six new particles have been discovered at the Large Hadron Collider (LHC) so far: the Higgs boson, 52 conventional ...

Hadrons are made of even smaller particles called quarks, which are held together ... One exciting discovery is the role of the pion, a particle that connects two important ideas in the Standard ...

Researchers believe that the trace anomaly is crucial for keeping quarks bonded in subatomic particles. In a study published ...

Are these predictions naive, or is this the first glimpse of why there is more matter than antimatter in the universe? Previously, only the three light quarks (up, down and strange) were known.

Scientists also want to understand how the mass from quarks and gluons is distributed ... how mass is spread out within particles like the pion and the nucleon. The results suggest that the ...

arise from the distributions of their constituent quarks and gluons," said Brookhaven Lab theorist Swagato Mukherjee, who led the research. The lightest meson, the pion, plays an essential role in ...
