V − A Constraint on a Product of R - parity Violating Couplings
نویسندگان
چکیده
We study in the framework of R-parity violating supersymmetric theories the effect of R-parity violation due to the operator L i L j E k on the (V − A) structure of the muon decay. The precisely measured muon decay parameters can constrain a product of R-parity violating couplings: |λ 232 λ 131 | < 0.022 at the 90% CL, which is complementary to the previous limits obtained by the e-µ universality in τ decay.

Constraints on the R - parity Violating Couplings from B ± → l ± ν Decays
We derive the upper bounds on certain products of R-parityand leptonflavor-violating couplings from B → lν decays. These modes of B-meson decays can constrain the product combinations of the couplings with one or more heavy generation indices which are comparable with or stronger than the present bounds. And we investigate the possible effects of R-parity violating interactions on Bc → lν decay...
متن کاملUpper bound on all products of R - parity violating couplings λ ′ and λ ′ ′ from proton decay
We prove that any product of R-parity violating couplings λ (L-violating) and λ (B-violating) can be strongly restricted by proton decay data. For any pair λ and λ the decay exists at least at one loop level. For squark masses below 1 TeV we find the conservative bounds |λ′ · λ′′| < 10 in absence of squark flavor mixing, and |λ′ · λ′′| < 10 when this mixing is taken into account. We study the d...
متن کاملNew Bounds on R-parity Violating Couplings
We use information from rare nonleptonic decays of heavy-quark mesons to put new bounds on the magnitudes of certain product combinations of baryon nonconserving Rparity violating couplings in supersymmetric models. Product combinations of lepton and baryon nonconserving R-parity violating couplings are also considered in the light of existing bounds on nucleon decay. Contrary to popular impres...

We derive the upper bounds on certain products of R-parityand leptonflavor-violating couplings from B → Xsli lj − decays. These modes of Bmeson decays can constrain the product combinations of the couplings with one or more heavy generation indices which are comparable with or stronger than the present bounds. From the studies of the invariant dilepton mass spectrum and the forward backward asy...

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...
