Description

With just two R-parity violating couplings, λ223' and λ323', we correlate several channels, namely, Ds→lν (l=μ,τ), (g-2)μ, and some lepton flavor violating τ decays. For λ223'=λ323'∼0.3 and for a common superpartner mass of 300 GeV, which explain the recently observed excesses in the above Ds decay channels, we predict the following R-parity violating contributions: Br(τ→μγ)∼4.5.10-8, Br(τ→μμμ)∼1.2.10-8, Br(τ→μη/η')∼4.10-10, and (gμ-2)/2∼4.10-11. We exhibit our results through observable versus observable correlation plots.
