A team of researchers has calculated the mass of a proton to be approximately 30 billionths of a percent less than previously thought. The researchers fired an electron beam at an atom held in a chilled vacuum chamber, releasing a proton. The released proton was then isolated in a Penning trap where its velocity could be accurately measured. By analyzing the proton’s velocity the team was able to calculate its mass as 1.007 276 466 583(15)(29) AMU.

The LHCb experiment at CERN's Large Hadron Collider has reported the observation of Xicc++ -- a new particle containing two charm quarks and one up quark. The existence of this particle from the baryon family was expected by current theories, but physicists have been looking for such baryons with two heavy quarks for many years. The mass of the newly identified particle is about 3621 MeV, which is almost four times heavier than the most familiar baryon, the proton, a property that arises ...

The proton is a subatomic particle with the symbol p or p+ and a positive electric charge of 1 elementary charge. One or more protons are present in the nucleus of each atom, along with neutrons. The number of protons in each atom is its atomic number. In the standard model of particle physics, the proton is a hadron, composed of quarks. A proton is composed of two up quarks and one down quark, with the rest mass of the quarks thought to contribute only about 1% of the proton's mass.
