Experimental Review of Exclusive Semileptonic B Meson Decays and Measurements of |Vub|
نویسنده
چکیده
The Standard Model (SM) of particle physics contains a number of parameters whose values are not predicted by theory and must therefore be measured by experiment. In the quark sector, the elements of the 3 × 3 Cabibbo-Kobayashi-Maskawa (CKM) matrix [1] govern the weak transitions between quark flavours, and precision measurements of their values are desirable. In particular, much experimental and theoretical effort is currently being employed to test the consistency of one of the six “Unitarity Triangles” arising from the CKM formalism, the one most relevant to the decays of B mesons.

New Results on Flavor Physics
Recent progress in flavor physics is discussed. In particular, I review theoretical and experimental developments relevant for semileptonic B decays and the determination of |Vcb| and |Vub|, for exclusive rare decays, for nonleptonic b → c decays and tests of factorization, and for D meson mixing.

متن کاملSemileptonic B Decays at BABAR∗
We present results on semileptonic B decays obtained with the BABAR detector. The large data set accumulated at the PEP-II asymmetric-energy B-Factory allows a new measurement technique, where the hadronic decay of one B meson is fully reconstructed and the semileptonic decay of the recoiling B meson is studied. Traditional analysis techniques of inclusive and exclusive B decays complement this...
متن کاملIsospin corrections to charmless semileptonic B-->V transitions.
We compute isospin corrections to the charmless semileptonic B → V transitions arising from ρ− ω mixing and discuss its relevance in the determination of Vub. PACS numbers: 13.20.He, 12.15.Hh, 12.40.Vv. 11.30.Hv The first measurement of an exclusive charmless semileptonic B decay has been reported recently by the CLEO Collaboration [1,4]. The yields for B → πlνl reported in Refs. [1,4] turn out...
متن کاملSemileptonic Decays of B Mesons
In this section, we discuss some of the key questions related to semileptonic decays of B mesons: the inclusive semileptonic branching fraction, the determination of jV cb j and jV ub j from inclusive and exclusive measurements, recent progress in exclusive semileptonic decays, and form factor measurements and tests of heavy-quark eeective theory. We emphasize the uncertainties that arise in ex...
متن کاملSemileptonic B Decays at the B Factories
Semileptonic B decays provide direct access to the CKM matrix elements Vub and Vcb, whose ratio gives a measurement of the side of the Unitarity Triangle opposite the angle β. The underlying theory of semileptonic B decays is at an advanced stage. The weak currents factorize in leptonic and hadronic parts which do not interact between each other. Moreover, the b quark mass is considerably large...
