leptonic การใช้

• However, neutrino oscillations are known to violate the conservation of the individual leptonic numbers.
• His important estimates of the light and heavy quark masses and leptonic heavy-light mesons decay constants are compiled in the Particle Data Group ( PDG ).
• Also, it allowed the study of the leptonic decay of ? + and ?  " particles, and confirmed the validity of the ?Q / ?S = + 1 rule.
• Farida Tahir, M . Anwar Mughal, M Sadiq and K . Ahmed,  Bounds on R-parity violating SUSY Yukawa couplings from semi-leptonic decays of baryons, Phys.
• When Sugawara was still a graduate student at the University of Tokyo, he derived a relation for non-leptonic hyperon decay amplitudes called " Lee-Sugawara relation " while studying the symmetry of weak interactions.
• Several results for neutral kaons were obtained and published in the early 1970s, including the observation of the rare decay of the neutral kaon to a muon pair, the time-dependence of the asymmetry for semi-leptonic decays, and a more precise measurement of the neutral kaon mass difference.
• The B-factories yielded a rich harvest of results, including the first observation of CP violation outside of the kaon system, measurements of the CKM parameters | " V " ub | and | " V " cb |, measurements of purely leptonic B meson decays and searches for new Physics.
• There is intense research activity involving neutrinos, with goals that include the determination of the three neutrino mass values, the measurement of the degree of CP violation in the leptonic sector, which, if large enough, could provide a long-sought explanation ( leptogenesis ) for the excess of matter over anti-matter in the universe, and searches for evidence of physics beyond the Standard Model of particle physics such as neutrinoless double beta decay, which would be evidence for violation of lepton number conservation.
