We discuss the observability of the lightest neutral Higgs boson in the constrained MSSM (CMSSM), with universal soft supersymmetry-breaking parameters, at hadron colliders such as the Tevatron and the LHC. We take account of the constraints on parameter space provided by LEP, the measured rate of b → sγ decay, the cosmological relic density Ωχh , and the recent measurement of gμ − 2. We normal...

A new scenario of hybrid-like inflation is considered for sneutrino and MSSM fields. Contrary to the usual hybrid inflation model, the direct coupling between a trigger field and the sneutrino/MSSM inflaton field is not necessary for the scenario. The dissipation and the radiation from the sneutrino/MSSM inflaton can be written explicitly by using the Yukawa couplings. Remote inflation does not...

We apply the effective field theory definition of Minimal Flavour Violation (MFV) to the MSSM. We explicitly show how, by this definition, the new sources of flavour and CP violation present in the MSSM become functions of the SM Yukawa couplings, and cannot be simply set to zero, as is common wisdom in phenomenological MSSM studies that assume MFV. We apply our approach to the MSSM ∆B = 2 Hami...

In the study of mechanics and optimal control, one often encounters what is called a two-point boundary-value problem (TPBVP). A couple of methods exist for solving these problems, such as the Simple Shooting Method (SSM) and its variation, the Multiple Shooting Method (MSM). In this paper a new method is proposed that was designed from the favorable aspects of both the SSM and the MSM. The Mod...

We describe the implementation of the MSSM in the diagram generator FeynArts and the calculational tool FormCalc. This extension allows to perform loop calculations of MSSM processes almost fully automatically. The actual implementation has two aspects: The MSSM Feynman rules are specified in a new model file for FeynArts. The computation of the parameters in the MSSM Lagrangian from the input ...

We present a MSSM study of the b → sγ decay in a Minimal Flavor Violating (MFV) framework, where the form of the soft SUSY breaking terms is determined by the Standard Model Yukawa couplings. In particular, we address the role of gluino contributions, which are set to zero in most studies of the MFV MSSM. Gluino contributions can play an important role in the MFV MSSM whenever μ × tanβ is large...

In the Minimal Supersymmetric Standard Model (MSSM) it is assumed that R-parity (Rp) is conserved . While the particles of the Standard Model are even under Rp, their supersymmetric partners are odd, thus the latter can only be produced in pairs and they always decay into final states involving an odd number of supersymmetric particles. Although it considerably simplifies the structure of the M...

In the MSSM, the CP parities of the neutral Higgs bosons may be mixed by radiative effects induced by explicit CP violation in the third generation of squarks. To allow for this possibility, we argue that the charged Higgs-boson mass and tan β should be used to parametrize the MSSM Higgs sector. We introduce a new benchmark scenario of maximal CP violation appropriate for direct searches of CP-...

Common to many classes of three family SU(3)C × SU(2)L ×U(1)Y string models are an additional anomalous U(1)A and numerous, often fractionally charged, exotic particles beyond the minimal supersymmetric standard model (MSSM). I present one string model with both of these properties. Using this model as an example, I show how sometimes (near) string scale vacuum expectation values that are both ...

A bstract In the NonHolomorphic Supersymmetric Standard Model (NHSSM), Yukawa couplings of bottom quark ( y b ) and tau lepton ? might receive substantial supersymmetric (SUSY) radiative corrections which have prominent dependencies on NHSSM-specific trilinear soft parameters, $$ {A}_b^{\prime } A b...
