Natural flavour mixing in the MSSM and $μ - - > e, γ$

B. de Carlos, J. A. Casas, J. M. Moreno

In the absence of any additional assumption it is natural to conjecture that sizeable flavour-mixing mass entries, $Δ m^{2}$ , may appear in the mass matrices of the scalars of the MSS…

New and Strong Constraints on the Parameter Space of the MSSM from Charge and Color Breaking Directions

J. A. Casas

Although the possible existence of dangerous charge and color breaking (CCB) directions in the MSSM has been known since the early 80's, only particular directions in the field-spa…

Supergravity and the $b \to s, γ$ decay

B. de Carlos, J. A. Casas

We evaluate the branching ratio BR( $b \to s, γ$ ) in the minimal supersymmetric standard model (MSSM), determining the corresponding phenomenological restrictions on two attra…
