We investigate the experimentally allowed parameter space of an extension of the standard model (SM3) by one additional family of fermions. Therefore we extend our previous study of the Cabibbo-Kobayashi-Maskawa (CKM)-like mixing constraints of a fourth generation of quarks. In addition to the bounds from tree-level determinations of the 3x3 CKM elements and flavor-changing neutral currents processes (K, D, B{sub d}, B{sub s} mixing and the decay b{yields}s{gamma}) we also investigate the… Expand

The generalization of the MSSM to the case of four chiral fermion generations (4GMSSM) can lead to significant changes in the phenomenology of the otherwise familiar Higgs sector. In most of theExpand

Like-sign dimuon charge asymmetry in the Randall-Sundrum model

We confirm that in order to account for the recent D0 result of large like-sign dimuon charge asymmetry, a considerable large new physics effect in {Gamma}{sub 12}{sup s} is required in addition to aExpand

Muon g-2 and lepton flavor violation in a two Higgs doublets model for the fourth generation
• Physics

Abstract In the minimal Standard Model (SM) with four generations (the so-called SM4) and in “standard” two Higgs doublets model (2HDM) setups, e.g., the type II 2HDM with four fermion generations,Expand
Z-mediated charge and CP asymmetries and FCNCs in Bd,s processes

Implications of large dimuon CP asymmetry in Bd,s decays on minimal flavor violation with low tan β
• Physics
• 2010
The D0 collaboration has recently announced evidence for a dimuon CP asymmetry in Bd,s decays of order one percent. If confirmed, this asymmetry requires new physics. We argue that for minimallyExpand
