Abstract
We present a novel dynamics for generating sizable CP-violating asymmetries in the decays of charged B∓→π∓ω,π∓ρ0,π0ρ∓, and in B0(B0)→π∓ρ±. The dynamics for the necessary final-state interactions involves the mixing of G-parity eigenstates of the system (D∗D,D∗D) with the G=±1 states of πω and πρ, respectively. The dynamical effect is enhanced by the empirically large branching ratio for decays to (D∗D,D∗D). A correlated result is a markedly enhanced branching ratio for B0(B0)→π0ρ0, which has now been observed in two experiments.
Highlights
Direct CP violation in the decays of charged and neutral B mesons is the central theme in current experiments [1, 2, 3] at the two B-meson factories
One experiment [2] has given a large direct CP violation in B0(B0) → π−π+.[8]. This group has given an indication [3] of a sizable asymmetry in B∓ → π∓ω
We show how sizable asymmetries can occur in π∓ω, π∓ρ0, π0ρ∓, due to small, strong-interaction mixings with states of D∗D and D∗D
Summary
Direct CP violation in the decays of charged and neutral B mesons is the central theme in current experiments [1, 2, 3] at the two B-meson factories. In order to have direct CP violation observable, there must be (strong) interactions among particles in the final states.[6] It is physically clear that if there exists a decay channel with an empirically large branching ratio
