R-Parity violating minimal supergravity at the LHC
نویسنده
چکیده
We consider the case where supersymmetry with broken R-parity is embedded in the minimal supergravity model (mSUGRA). This alters the standard mSUGRA spectrum and opens a wide range in parameter space, where the scalar tau is the lightest supersymmetric particle, instead of the lightest neutralino. We study the resulting LHC phenomenology. Promising signatures would be detached vertices from long-lived staus, multi lepton final states and multi-tau final states. We investigate in detail the corresponding cross sections and decay rates in characteristic benchmark scenarios.

→ μ + μ − decay in the R - parity violating minimal supergravity
We study Bs → μ+μ− in the context of the R-parity violating minimal supergravity in the high tan β regime. We find that the lowest value of the branching ratio can go well below the present LHCb sensitivity and hence Bs → μ+μ− can even be invisible to the LHC. We also find that the present upper bound on Br(Bs → μ+μ−) puts strong constraint on the minimal supergravity parameter space. The const...
متن کاملAll Possible Lightest Supersymmetric Particles in R-Parity Violating mSUGRA Models and their Signals at the LHC
We consider minimal supergravity (mSUGRA) models with an additional R-parity violating operator at the grand unification scale. This can change the supersymmetric spectrum leading on the one hand to a sneutrino, smuon or squark as the lightest supersymmetric particle (LSP). On the other hand, a wide parameter region is reopened, where the scalar tau is the LSP. It is vital to know the nature of...

We investigate in detail the effects of the R-parity lepton number violation in the minimal supersymmetric standard model (MSSM) on the parent process pp → ee+X at the CERN Large Hadron Collider (LHC). The numerical comparisons between the contributions of the R-parity violating effects to the parent process via the Drell-Yan subprocess and the gluongluon fusion are made. We find that the R-vio...
متن کاملStop production in R-parity violating supersymmetry at Tevatron
Constraints for stop production in R-parity violating supersymmetry at Tevatron have been evaluated using the D0 limits for first generation leptoquarks. Such limits have been converted in constraints for the λ′131 R-parity violating coupling as a function of the stop mass for different Minimal Supersymmetric Standard Model (MSSM) scenarios and compared with Atomic Parity Violation and HERA res...
متن کاملB s → μ + μ − decay in the R - parity violating minimal supergravity
We study Bs → μ+μ− in the context of the R-parity violating minimal supergravity in the high tanβ regime. We find that the present upper bound on Br(Bs → μ+μ−) puts strong constraint on the minimal supergravity parameter space. The constraints become more severe if the upper bound is close to its standard model prediction. We also find that the minimum value of the branching ratio can go well b...
