Non-leptonic charmless Bc decays (and their search at LHCb)
نویسنده
چکیده
We discuss the decay of Bc mesons into two light mesons (π,K (∗), η(′), ρ, ω, φ). All these decay channels come from a single type of diagram, namely tree annihilation. This allows us to derive extremely simple SU(3) relations among these processes. The size of annihilation contributions is an important issue in B physics, and we provide two different estimates in the case of non-leptonic charmless Bc decays, either a comparison with annihilation decays of heavy-light mesons or a perturbative model inspired by QCD factorisation. We finally discuss a possible search for these channels at LHCb.

Towards a Theory of Charmless Non-leptonic Two-body B Decays
We address a number of theoretical and phenomenological issues in two-body charmless non-leptonic B decays in the context of a factorization model. A classification of the exclusive decays involving tree and penguin amplitudes is reviewed. The role of QCD anomaly in exclusive decays involving an η or η ′ is elucidated and comparison is made with the existing data. We argue that the factorizatio...
متن کاملRare leptonic and semileptonic b-hadron decays and tests of lepton flavour universality at LHCb
Rare decays of heavy-flavoured particles provide an ideal laboratory to look for deviations from the Standard Model, and explore energy regimes beyond the LHC reach. Decays proceeding via electroweak penguin diagrams are excellent probes to search for New Physics, and b→ s`+`− processes are particularly interesting since they give access to many observables such as branching fractions, asymmetr...
متن کاملA Novel PQCD Approach in Charmless B - meson Decays
We discuss a novel pertubative QCD approach on the exclusive non-leptonic two body B-meson decays. We briefly review its ingredients and some important theoretical issues on the factorization approaches. We show numerical results which is compatible with recent experimantal data for the charmless B-meson decays.

The semileptonic decays of meson Bc to a P-wave charmonium state χc( PJ) or hc( P1) are computed. The results show that the decays are sizable so they are accessible in Tevatron and in LHC, especially, with the detectors LHCB and BTeV in the foreseeable future, and of them, the one to the P1 charmonium state potentially offers us a novel window to see the unconfirmed hc particle. In addition, i...
