چکیده

The recent observation of B d → ππ and B̄ d → ππ decay modes allows us to make a fresh isospin analysis of B → ππ transitions. We find that current experimental data can impose some model-independent constraints on the parameter space of direct CP violation in Bd → ππ and Bd → ππ. Furthermore, we establish a direct relationship between the weak phase α and the charge-averaged branching fractions and CP-violating asymmetries of B → ππ decays.

Direct CP Violation in B Decays

We discuss several aspects of direct CP asymmetries in B decays, which are very useful in spite of hadronic uncertainties in asymmetry calculations. 1) Asymmetries in decays to D(∗)K(∗), π+π−, ρ+ρ−, providing precision tests for the CKM phase γ. 2) Null tests in B+ → J/ψK+, π+π0, where a nonzero asymmetry provides evidence for New Physics. 3) Isospin and broken flavor SU(3) relations among CP a...

Improving Bounds on Penguin Pollution in B → ππ

In the presence of penguin contributions, the indirect CP asymmetry in B(t) → ππ measures sin(2α + 2θ), where 2θ parametrizes the size of the penguin “pollution.” We present a new upper bound on |2θ|, involving also the measurement of B → ππ, along with an upper bound on or a measurement of BR(B → ππ)+BR(B0 → ππ). The new bound is stronger than those previously discussed in the literature. Inde...

Searching for New Physics via CP Violation in B → ππ

It is well known that one can use B → ππ decays to probe the CP-violating phase α. In this paper we show that these same decays can be used to search for new physics. This is done by comparing two weak phases which are equal in the standard model: the phase of the t-quark contribution to the b → d penguin amplitude, and the phase of B d–B 0 d mixing. In order to make such a comparison, we requi...

The Impact of |∆I | = 5/2 Transitions in K → ππ Decays

We consider the impact of isospin violation on the analysis of K → ππ decays. We scrutinize , in particular, the phenomenological role played by the additional weak amplitude, of |∆I| = 5/2 in character, incurred by the presence of isospin violation. We show that Watson's theorem is appropriate in O(m d − m u), so that the inferred π − π phase shift at √ s = m K determines the strong phase diff...

Isospin Breaking in K → ππ Decays ∗

We perform a complete analysis of isospin breaking in K → 2π amplitudes in chiral perturbation theory, including both strong isospin violation (m u = m d) and electromagnetic corrections to next-to-leading order in the low-energy expansion. The unknown chiral couplings are estimated at leading order in the 1/N c expansion. We study the impact of isospin breaking on CP conserving amplitudes and ...
