A proton’s core consists of three valence quarks, but they contribute only a small fraction of the proton's mass. Most of the mass emerges from intricate quark dynamics and is primarily ...

The first precise mass measurements of an extremely short-lived and proton-rich nucleus, silicon-22, have revealed the “magic” – that is, unusually tightly bound – nature of nuclei containing 14 ...

A research group at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) presented an analysis of the proton mass radius in Physical Review D on May 11. The proton mass ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...

Only 1% of the mass of the proton comes from the Higgs field. ALICE scientists examine a process that could help explain the rest.

Scientists measure proton's mass with record precision Researchers measured the proton's mass at 1.007276466583 atomic mass units -- three times more precise than the currently accepted value.

The calculations suggest that the mass of the nucleon (the calculation cannot distinguish between protons and neutrons) to be 936 MeV/C 2 with statistical and systematic uncertainties of ±25 and ±22 ...

The resulting mass of the proton, determined to be 1.007276466583 (15) (29) atomic mass units, is three times more precise than the presently accepted value. The numbers in parentheses refer to the ...
