WebConserved' means that the sum of the baryon number of all incoming particles is the same as the sum of the baryon numbers of all particles resulting from the reaction. The one exception is the hypothesized Adler–Bell–Jackiw anomaly in electroweak interactions ; [4] however, sphalerons are not all that common and could occur at high energy and … WebBaryon number is conserved, since all particles have B = 0. Mass-energy is conserved in the sense that the K+ has a greater mass than the products, so that the decay can be spontaneous. Lepton family numbers are conserved at 0 for the electron and tau family for all particles. The muon family number is Lμ = 0 before and Lμ = −1+1 = 0 after. Web30 mei 2024 · 1. I was wondering how neutrino oscillations are possible and lepton number is conserved, as for example in the decay of an anti-muon: μ + = e + ν e ν μ ¯. all lepton numbers are conserved, but let’s now imagine the anti-muon neutrino oscillate to an anti-tau neutriono, then we finally have: μ + = e + ν e ν τ ¯. reading log printable with books
