Evidence for Non-Baryonic Dark Matter in High Energy Regions above 10 GeV

Abstract

At an infinite sublayer level, there exists an infinite number of quarks u(\(\infty\)) with the flavors f=u,d,s,c,b and anti-quarks u(\(\infty\)) having all one-half electric charge Q=±1/2. These particles are considered as the ultimate building blocks of the universe, since they are structure-less and absolutely stable. These particles are also regarded as the non-baryonic dark matter, since the baryon number is zero and the R_p-parity is -1. It is emphasized that supersymmetric particle, neutralino has also the R_p-parity of -1 and well known good cold dark matter candidate. In modern particle physics, all ordinary particles have the R_p-parity of+1, while both the ultimate quarks and u(\(\infty\)) neutralino have the -parity of R_p-1 This means that these particles can only be created or annihilated in pairs in reactions of ordinary particles. From electron-positron annihilation experiments at high energies, it is shown that the prediction value from the ultimate quark u(\(\infty\)) is in good agreement with many ring-storage collider experiments.
