A Reexamination of Proton Decay in Supersymmetric Grand Unified Theories
We reconsider dimension–five proton decay operators, making semiquantitative remarks which apply to a large class of supersymmetric GUTs in which the short-distance operators are correlated with the fermion Yukawa couplings. In these GUTs, which include minimal SU(5), the operators (udi ) (djντ ), induced by charged Higgsino dressing, completely dominate for moderate to large tan β. The rate fo...

متن کاملSUPPRESSION OF d = 5 OPERATOR INDUCED PROTON DECAY IN SUPERSYMMETRIC GRAND UNIFIED THEORIES
The proton decay in supersymmetric (SUSY) Grand Unified Theories (GUTs), where the special mechanism provides the natural suppression of the dimension 5 (d = 5) operators, was studied. Due to this mechanism, d = 5 operator induced proton decay takes place only through the mixing of light generation fermions with those from third generation and crucially depends on the structure of fermion mass ...
متن کاملGrand Unified Theories
In spite of all the successes of the Standard Model [SM] it is unlikely to be the final theory. It leaves many unanswered questions. Why the local gauge interactions SU(3)C × SU(2)L × U(1)Y and why 3 families of quarks and leptons? Moreover why does one family consist of the states [Q, u, d; L, e] transforming as [(3, 2, 1/3), (3̄, 1,−4/3), (3̄, 1, 2/3); (1, 2,−1), (1, 1, 2)], where Q = (u, d) an...
متن کاملµ → eγ AND µ → 3e PROCESSES WITH POLARIZED MUON AND SUPERSYMMETRIC GRAND UNIFIED THEORIES a
Lepton flavor violating processes μ → eγ and μ → 3e with polarized muons are studied in the supersymmetric grand unified theory (SUSY GUT). As a result of a detailed numerical calculation, it is shown that the Pand T-odd asymmetries defined with the help of the muon polarization and the ratio of two branching fractions make a good contrast between the SU(5) and SO(10) SUSY GUT. These observable...
