Observing Direct CP Violation in Untagged B-Meson Decays
Abstract Direct CP violation can exist in untagged B-meson decays to self-conjugate, three-particle final states; it would be realized as a population asymmetry in the untagged decay rate across the mirror line of the Dalitz plot of the three-body decay. We explore the numerical size of this direct CP-violating effect in a variety of B-meson decays to three pseudoscalar mesons; we show that the...
متن کاملDirect CP Violation in Untagged B-Meson Decays
Direct CP violation can exist in untagged, neutral B-meson decays to certain self-conjugate, hadronic final states. As a necessary condition, the resonances which appear therein must permit the identification of distinct, CP-conjugate states — in analogy to stereochemistry, we term such states “CP-enantiomers.” These states permit the construction of CP-even and CP-odd amplitude combinations an...

متن کاملCP violation in B-meson decays
The pattern of CP violation in the bottom sector is discussed. We introduce general techniques to expose new CPviolating effects in the cascade decays of B mesons. In the Kobayashi-Maskawa (KMj model, the CP asymmetries so obtained range from 2—20% for plausible values of the model parameters. This is to be compared with the small effects, of order 10 '-10 ', previously exhibited within this mo...
متن کاملDirect 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...
