Abstract
We study the exclusive decays of by results in perturbative QCD with the heavy quark effective theory and lattice calculations. We obtain the form factors for the transitions in the whole allowed region. Our predictions for the branching ratios of and are and 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 can be used to probe new physics.
