The never observed decay of this particle is one test for proposed GUTs. Most cosmic rays consist of high energy examples of this particle. Along with a slightly heavier particle, this particle's interior composition is predicted by QCD. The major nuclear reaction in the sun is named for this particle, four of which are converted into a heavier particle in on turn of the cycle. This baryon is formed from two up quarks and a down quark, giving it a positive charge. One of these particles and an electron are the products of beta decay. For 10 points, name this particle found in the atomic nucleus along with the neutron.
