Setting Limits on Supersymmetry Using Simplified Models

Higgs-mediated B0 --> &mgr;(+)&mgr;(-) in minimal supersymmetry
Abstract:
We demonstrate a new source for flavor-changing neutral currents within the minimal supersymmetric standard model. At moderate to large tanbeta, it is no longer possible to diagonalize the masses of the quarks in the same basis as their Yukawa couplings. This generates flavor-violating couplings of the form &bmacr;(R)d(L)straight phi and &bmacr;(R)s(L)straight phi where straight phi is any of the three neutral, physical Higgs bosons. These new couplings lead to rare processes in the B system such as B0-->&mgr;(+)&mgr;(-) and B0-&Bmacr;(0) mixing. We show that the latter are anomalously suppressed, while the former is in the experimentally interesting range, with an observable signal possible at Run II of the Tevatron if m(A) less, similar400-700 GeV.

Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
