R-parity
|
|
R-parity is a concept in particle physics. In the extension of the Standard Model to include supersymmetry, baryon and lepton numbers of particles are no longer assumed to be conserved. Instead R-parity may be conserved, where the R-parity is
- R = (-1)2j+3B+L.
With spin j, baryons B, and leptons L. All Standard Model particles have R-parity of 1 while supersymmetric particles have R-parity -1. R-parity violations may point towards new physics.
