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...

A precise sum rule among four B → Kπ CP asymmetries

A sum rule relation is proposed for direct CP asymmetries in B → Kπ decays. Leading terms are identical in the isospin symmetry limit, while subleading terms are equal in the flavor SU(3) and heavy quark limits. The sum rule predicts ACP(B 0 → Kπ) = −0.17±0.06 using current asymmetry measurements for the other three B → Kπ decays. A violation of the sum rule would be evidence for New Physics in...

Purely Flavored Leptogenesis

We study a model for leptogenesis in which the total CP asymmetries in the decays and scatterings involving the SU(2) singlet seesaw neutrinos Nα vanish (ǫNα = 0). Leptogenesis is possible due to non-vanishing CP violating lepton flavor asymmetries, realizing a situation in which the baryon asymmetry is due exclusively to flavor effects. We study the production of a net lepton asymmetry by solv...

Beyond the Standard Model

We analyze the decay KL → π0νν̄ in a model independent way. If lepton flavor is conserved the final state is (to a good approximation) purely CP even. In that case this decay mode goes mainly through CP violating interference between mixing and decay. Consequently, a theoretically clean relation between the measured rate and electroweak parameters holds in any given model. Specifically, Γ(KL → π...

Maximal Neutrino Mixing and Maximal CP Violation

We propose a phenomenological model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flavor mixing pattern, which is favored by current data on atmospheric and solar neutrino oscillations, emerges naturally from this model after explicit symmetry breaking. The rephasing-invariant strength of CP or T viola...
