Penguins and Mixing Dependent CP Violation
نویسنده
چکیده
Constraints on angles of Unitarity triangle are reviewed, and in particular constraint on γ from limit on ∆m s is emphasized. Effects of penguin diagram on measurement of β and α are then reviewed. New measurements on B → π + π − in QCD improved factorization approximation suggest large penguin effects. It is possible to estimate the error in measurement of α as a function of γ for different |V ub /V cb | values.

Mixing - induced CP Violation in the Decay B d → K 0 K̄ 0 within the Standard Model
Recently, flavour SU(3) symmetry of strong interactions has been combined with certain dynamical assumptions to derive triangle relations among B-meson decay-amplitudes. We show that these relations allow a prediction of the mixinginduced CP asymmetry Amix-ind CP (Bd → KK̄). Contrary to statements made in several previous papers, this asymmetry should be non-vanishing in the Standard Model due t...
متن کاملSize 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...

متن کاملQuark Mixing, CP Violation and Rare Decays After the Top Quark Discovery
We review the highlights of quark mixing, particle–antiparticle mixing, CP violation and rare Kand B-decays in the Standard Model. The top quark discovery, the precise measurement of its mass, the improved knowledge of the couplings Vcb and Vub, and the calculations of NLO short distance QCD corrections improved considerably the predictions for various decay rates, the determination of the coup...
متن کاملExperimental Prospects for Cp Violation in Charm
Experimental sensitivity to CP violation in charm decay is beginning to approach the interesting regime (∼ 10) in which new physics may be manifest. In the early years of the 21st century, if the technical challenges can be met, the proposed BTeV experiment should have the best sensitivity for rare effects both in charm and in beauty. 1 Charm CP Violation in the Standard Model and Beyond The St...
