Assuming that the conserved currents are sources of the vector meson fields, the vector fields Z's coupled to baryon and lepton number are discussed. 根据守恒流是矢介子场的源的概念,讨论了重子数和轻子数所对应的矢介子场Z。
It is proved that only lepton charge is strictly conserved and the individual conservation of the lepton number of every generation of leptons hold only approximately. 证明了只有轻子荷才是严格守恒的,各代轻子数分别守恒只能近似成立。
Double beta decay in nuclei plays an important role in testing lepton number conservation and neutrino mass. 原子核双β衰变在检验轻子数守恒律和中微子质量等问题上都起了重要的作用。
The possible appearance of the R-parity violating ( RPV) couplings, which will violate the lepton and baryon number conservation, has gained full attention in searching for the SUSY. 在寻找超对称时,可能存在的破坏轻子数和重子数的R宇称破缺耦合受到了充分关注。
