Scientists Gain New Insights into How Mass Is Distributed in Hadrons

Department of Energy, Office of Science — Thu, 14 Nov 2024 17:20:32 EST

The trace anomaly is one of the quantities that encodes the energy and momentum of particles built from quarks. Scientists believe the trace anomaly is crucial for keeping quarks bonded in subatomic particles. In this study, scientists calculated the trace anomaly for nucleons and pions. The calculations show that in the pion, the mass distribution is similar to the charge distribution of the neutron and in the nucleon, the mass distribution is similar to the charge distribution of the proton.
