Dark matter, cosmic positrons in alpha magnetic spectrometer experiment and particle-cosmology with Yang–Mills gravity

We discuss a model of dark matter consisting high energy anti-electron-neutrinos with leptonic force, which is produced by the conserved charge gℓ associated Lee–Yang’s U1 gauge symmetry. Based on particle-cosmology for early universe, neutrino (HEN) assumes that neutron decay processes, n→p++e−+ν¯e, dominate epoch after creation, collision and confinement processes quarks antiquarks in beginning. The HEN implies following results: There are almost equal numbers electrons, protons dominated cosmos. unobservable ubiquitous ν¯e universe. Although total mass anti-electron-neutrino negligible its enhanced gravitational forces could lead to observed flat rotation curves due relativistic ν¯e, whose static force involves factor Eν/mν≈106. estimate be gℓ≈7×10−21. predicts can interact cosmic-ray produce positrons, i.e. ν¯e+p+→e++n, through weak interaction unified electroweak theory. sheds light Alpha Magnetic Spectrometer (AMS) experiment, has detected intriguing excess positrons over what expected. suggests an experimental test new Lee–Yang between electrons using modern precision Cavendish experiment.
