On the role of the final state interactions in rare B-decays | | A.B. Kaidalov

14 Jul 2008 | | Abstract: | The effects of final state interactions (FSI) in hadronic B-decays are
investigated. The model for FSI, based on Regge phenomenology of high-energy
hadronic interactions is proposed. It is shown that this model explains the
pattern of phases in matrix elements of $B opipi$ and $B o
ho
ho$ decays.
These phases play an important role for CP-violation in B-decays. The most
precise determination of the unitarity triangle angle $alpha$ from $B_d o
hopi$ decays is performed. The relation between CP-asymmetries in $B o
Kpi$ decays is discussed. It is emphasized that the large distance FSI can
explain the structure of polarizations of the vector mesons in B-decays and
other puzzles like a very large branching ratio of the B-decay to
$arXi_cLambda_c$. | | Source: | arXiv, 0807.2126 | | Services: | Forum | Review | PDF | Favorites | |
