Running Into New Territory in SUSY Parameter Space

چکیده
The LEP-II bound on the light Higgs mass rules out the vast majority of parameter space left to the Minimal Supersymmetric Standard Model (MSSM) with weakscale soft-masses. This suggests the importance of exploring extensions of the MSSM with non-minimal Higgs physics. In this article, we explore a theory with an additional singlet superfield and an extended gauge sector. The theory has a number of novel features compared to both the MSSM and Next-to-MSSM, including easily realizing a light CP-even Higgs mass consistent with LEP-II limits, tan β . 1, and a lightest Higgs which is charged. These features are achieved while remaining consistent with perturbative unification and without large stop-masses. Discovery modes at the Tevatron and LHC are discussed.

Constraints on Supersymmetric Flavor Changing Parameters Using B → PP Decays
We study contributions of quark-squark-gluino interactions in Minimal Supersymmetric Standard Model (MSSM) to B → PP (PP = Kπ, ππ,KK) decays using QCD improved factorization method for the evaluation of the hadronic matrix elements and taking into account renormalization group running of the Wilson coefficients from SUSY scale (≈ mq̃) to the low energy scale (= mb) applicable to B decays. Using ...
متن کاملA Bottom-Up Approach to SUSY Analyses
This paper proposes a new way to do event generation and analysis in searches for new physics at the LHC. An abstract notation is used to describe the new particles on a level which better corresponds to detector resolution of LHC experiments. In this way the SUSY discovery space can be decomposed into a small number of eigenmodes each with only a few parameters, which allows to investigate the...
متن کاملDark Matter in the MSSM
We have recently examined a large number of points in the parameter space of the phenomenological MSSM, the 19-dimensional parameter space of the CPconserving MSSM with Minimal Flavor Violation. We determined whether each of these points satisfied existing experimental and theoretical constraints. This analysis provides insight into general features of the MSSM without reference to a particular...
متن کاملThe Relationship between the Enclosed Space and the Sense of Territory in Residential Neighborhoods (Case Study: Comparison between Haft-Hoz and Shahrake-Gharb)
Organization of living environment is possible through a clear definition of private and public arenas and determinationof a spatial hierarchy. Such defined arenas increase the sense of belonging to the environment which personalizesresidential environments. Enclosure is among the quantities that play a significant role in defining the spaces. In fact,enclosure is the factor that defines a spac...
متن کاملSUSY effects in Penguin dominated modes B → φK and B → φK ∗
Recent measurement of time dependent asymmetries in B → φK are indicative of a new source of CP violation. We examine squark mixing in SUSY as this new source, and using QCD improved factorization method to describe B → φK decay, find the allowed range of parameter space for ρ and ψ, the magnitude and phase of the down type LR(RL) squark mixing parameter δbs LR(RL). We then studyB → φK∗ and cal...
