Probing new physics in [Formula Presented] decays

Research output: Contribution to journalArticle

Abstract

We study the exclusive decays of (Formula presented) by results in perturbative QCD with the heavy quark effective theory and lattice calculations. We obtain the form factors for the (Formula presented) transitions in the whole allowed region. Our predictions for the branching ratios of (Formula presented) (Formula presented) and (Formula presented) are (Formula presented) (Formula presented) and (Formula presented) where the errors are from the quark mixing elements and hadronic effects, respectively. We also find that our definitions of the T-odd observable and the up-down asymmetry of the K meson in (Formula presented) can be used to probe new physics.
