Three-body decays of χ̃1 in R/p models with dominant λ and λ′ couplings

چکیده

Decays of the lightest neutralino are studied in Rp-violating models, with operators λ′LQDc and λLLEc involving third-generation matter fields and with dominant λ′ and λ couplings. Decays with the top-quark among the particles produced are considered, in addition to those with an almost massless final state. Phenomenological analyses for examples of both classes of decays are presented. No specific assumption on the composition of the lightest neutralino is made. Our formulae can easily be generalized to study decays of heavier neutralinos. We also discuss effects of the R/p decays of the χ̃1 on the possible faking of the H ± signal at the LHC by the recently pointed out τ̃ b̄t production through λ′333 coupling.

Measuring Supersymmetric Particle Masses at the LHC in Scenarios with Baryon–Number R-Parity Violating Couplings

The measurement of sparticle masses in the Minimal Supersymmetric Standard Model at the LHC is analysed, in the scenario where the lightest neutralino, the χ̃1, decays into three quarks. Such decays, occurring through the baryon-number violating coupling λ ijk, pose a severe challenge to the capability of the LHC detectors since the final state has no missing energy signature and a high jet mult...

Lightest - Neutralino Decays in R p - violating Models with Dominant λ ′ and λ Couplings

Decays of the lightest neutralino are studied in R p-violating models with operators λ ′ LQD c and λLLE c involving third-generation matter fields, and with couplings λ ′ and λ of O(1). Generalizations to decays of the lightest neutralino obtained when other subdominant λ ′ and λ couplings are present are straightforward. Both types of decays are considered: those with an almost massless final ...

Exotic SUSY scenarios

In this talk I discuss some scenarios which involve small extensions of the ideas usually considered in the Minimal Supersymmetric Standard Model (MSSM). I present results of a study of the implication of non-universal gaugino masses (NGM) for the invisible decays of the lightest scalar and the correlation of the same with the relic density of the lightest supersymmetric particle (LSP) in the U...

R-parity Violation and Semileptonic Decays of B-meson

We investigate the effects of R-parity violation on the semileptonic decays of B-meson in the minimal supersymmetric standard model with explicit R-parity violation and discuss its physical implications. We find that the semileptonic decays of B-meson can be largely affected by R-parity violation. PACS Number: 11.30.Fs, 13.25.Hw Typeset using REVTEX E-mail: [email protected] E-mail: ygki...
