Search for D+(s)→π+μ+μ− and D+(s)→π−μ+μ+ decays

Article history: Received 24 April 2013 Received in revised form 3 June 2013 Accepted 4 June 2013 Available online 7 June 2013 Editor: L. Rolandi A search for non-resonant D(s) → π+μ+μ− and D(s) → π−μ+μ+ decays is performed using proton– proton collision data, corresponding to an integrated luminosity of 1.0 fb−1, at √ s = 7 TeV recorded by the LHCb experiment in 2011. No signals are observed a...

The angular distribution of B → K ̄ ( = e, μ, τ ) depends on two parameters, the lepton forward– backward asymmetry, A FB, and the flat term, F H . Both are strongly suppressed in the standard model and constitute sensitive probes of tensor and scalar contributions. We use the latest experimental results for = μ in combination with the branching ratio of Bs → μ̄μ to derive the strongest modelind...

Shedding Light on the “ Dark Side ” of B 0 d – B 0 d Mixing through B d → π + π − , K → πνν and B d , s → μ + μ −

In a wide class of new-physics models, which can be motivated through generic arguments and within supersymmetry, we obtain large contributions to B0 d–B 0 d mixing, but not to ∆B = 1 processes. If we assume such a scenario, the solutions φd ∼ 47 ∨ 133 for the B0 d–B d mixing phase implied by Amix CP (Bd → J/ψKS) cannot be converted directly into a constraint in the ρ–η plane. However, we may c...
