چکیده

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, Hd, Vγ, VZ , V + W , V − W ). Three spectacular consequences ensue from Rp-conservation. First, each vertex involving sparticles has them in a pair. Second, the lightest supersymmetric particle (LSP χ̃1: a weakly interacting neutralino, escaping through detectors, being neutral on cosmological grounds) Plenary talk at the Pacific Particle Physics Phenomenology Workshop, Seoul, 31 Oct. – 2 Nov., 1997

Supersymmetric Theories with R–parity Violation

In these Lectures we review the Minimal Supersymmetric Standard Model as well as some of its extensions that include R–Parity violation. The cases of spontaneous breaking of R–Parity as well as that of explicit violation through bilinear terms in the superpotential are studied in detail. The signals at LEP and the prospects for LHC are discussed. 1 Lectures given at the V Gleb Wataghin School, ...

Theoretical and phenomenological implications of R-parity violation in supersymmetric theories are discussed in the context of particle physics and cosmology. Fundamental aspects include the relation with continuous and discrete symmetries and the various allowed patterns of R-parity breaking. Recent developments on the generation of neutrino masses and mixings within different scenarios of R-p...

The possible appearance of R-parity violating couplings, and hence implicitly the question of lepton and baryon number conservation, has been emphasised since the early development of supersymmetric theories. The rich phenomenology implied by R-parity violation has now gained full attention in the search for supersymmetry. In this review, theoretical and phenomenological implications of R-parit...

Lepton Number Violation in Decays of Supersymmetric Particles

We discuss lepton flavour violating signals at the LHC in the framework of supersymmetric theories. We consider R-parity conserving as well as R-parity violating scenarios. In the case of R-parity conservation we show that in decays of supersymmetric particles large regions in parameter exist where lepton flavour violating decay modes have large branching ratios despite the stringent constraint...

Bilinear R-parity Violation in Rare Meson Decays

Abstract. We discuss rare meson decays K → πll and D → Kll (l, l = e, μ) in a supersymmetric extension of the standard model with explicit breaking of R-parity by bilinear Yukawa couplings in the superpotential. Estimates of the branching ratios for these decays are given. We also compare our numerical results with analogous ones previously obtained for two other mechanisms of lepton number vio...
