SLAC - PUB - 7734 Review of Coherent Effects in B and Φ Factories

SLAC-PUB-11888 Rare hadronic B decays.

The study of rare hadronic B-meson decays with branching fractions O(10) enable us to probe a wide range of phenomena. Such decays can be used to probe our understanding of the CKM [1] description of quark mixing and CP violation (CPV ) in the Standard Model of Particle Physics (SM) by measuring all three of the Unitarity Triangle angles α, β and γ, as well as charge asymmetries in direct CPV ∆...

In this article I report on new and updated measurements of the CP-violating parameter β (φ1), which is related to the phase of the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing matrix of the electroweak interaction. Over the past few years, β has become the most precisely known parameter of the CKM unitarity triangle that governs the B system. The results presented here were produced by the two...

Semileptonic 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...

Size of Penguin Pollution of the CKM CP Violating

We use the perturbative QCD methods of Lepage and Brodsky to calculate the rate for ¯ B s → ρK S , with an eye toward the CP violating unitarity triangle angle γ. We show that , although the penguins are large, there are regions of the allowed parameter space of the Cabibbo-Kobayashi-Maskawa mixing matrix wherein γ is measurable in the sense that penguins change the value of sin(2γ) one would e...
