چکیده

In this analysis, we present a search for Beyond Standard Model physics in 9.2 fb−1 of √ s=8 TeV pp collision data from the Compact Muon Solenoid at the Large Hadron Collider. In particular, we consider leptonic R-Parity violations with λ122 = 0.005 in the mSUGRA parameter space characterized by m0=1000 GeV/c2, m 1 2 =900-1400 GeV/c2, A0=0, tan β=40, μ > 0, and mtop=172 GeV/c2. This study is carried out using Monte Carlo simulations and CLs statistical data analysis methods. We present an exclusion curve showing σ as a function of m 1 2 , indicating excluded regions of the parameter space, and suggest further study of an identified region of interest.

Supersymmetric theories with explicit R-parity violation∗

WMSSM = h u ijQi ·HiUj + hijQi ·HdD̄j + hijLi ·HdĒj + μHu ·Hd. (1) (1) has been constructed so as to conserve R-parity (even for particles, odd for sparticles) Rp ≡ (−1), B, L and s being baryon no., lepton no. and spin. This is equivalent to the conservation of matter parity which transforms the superfields as (Li, Ēi, Qi, Ūi, D̄i) → −(Li, Ēi, Qi, Ūi, D̄i), (Hu, Hd, Vγ, VZ , V + W , V − W ) → (Hu...

See-Saw Induced CMSSM Lepton-Flavour Violation Post-WMAP

The see-saw mechanism of neutrino mass generation, when incorporated in supersymmetric theories with supergravity mediated supersymmetry breaking, results in low-energy leptonflavour violation arising from the soft supersymmetry breaking slepton masses. The parameter space of supergravity theories with conserved R-parity is severely constrained by the requirement that the LSP provide cold dark ...

R-Parity violating minimal supergravity at the LHC

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 lo...

Single chargino production with R - parity lepton number violation in electron - electron and muon -

We examine single chargino production in conjunction with R-parity lepton number violation in future lepton-lepton collisions. Present bounds on R-parity violating couplings allow for a production cross section of the order of O(10 fb) for a wide range of sneutrino and chargino masses. Scenarios of chargino decay which lead to purely leptonic signals in the final state and without missing energ...
