6 Feb 2019 | Abstract: | A short review of our recent work on amplitude parametrizations of three-body
hadronic weak $B$ and $D$ decays is presented. The final states are here
composed of three light mesons, namely the various charge $pipipi$,
$Kpipi$ and $KKar K$ states. These parametrizations are derived from
previous calculations based on a quasi-two-body factorization approach where
the two-body hadronic final state interactions are fully taken into account in
terms of unitary $S$- and $P$-wave $pipi$, $pi K$ and $K ar K$ form
factors. They are an alternative to the isobar-model description and can be
useful in the interpretation of CP asymmetries. | Source: | arXiv, 1902.2138 | Services: | Forum | Review | PDF | Favorites |
