How baryon number is conserved in alpha/beta decay?

WebThere is a well-defined number to be associated with the electron field, corresponding to a globally conserved U (1) symmetry of the free electron Lagrangian density, as well as the weak and electromagnetic interactions, and that means that electron number is conserved. WebVideo Transcript. In this video, our topic is the conservation of baryon number. Baryon number is a property that’s possessed by all subatomic particles. In this lesson, we’ll learn how to figure out that number for a given particle and we’ll also see how it’s conserved in nuclear interactions. c# string to byte array utf-8WebThere are two possibilities of the violation of the law of conservation of the lepton number. 1. The lepton numbers Le, Lμ, and Lτ are violated separately, but the total lepton number L = Le + Lμ + Lτ is conserved. In this case the neutrinos ν i are the Dirac particles that possess the lepton number L = 1. c string to boolean

"WebAll lepton numbers add up to zero after the decay, and they are zero before the decay, since the Xi-minus is a baryon. The decay process conserves the three lepton numbers. The Xi-minus particle has spin quantum number s = 1/2, charge q = -e, and strangeness quantum number S = -2. " - How is baryon number conserved in alpha decay
