Title: Exclusive charmless nonleptonic decays of the B sub d sup 0 meson in the standard model

Abstract

We have studied the charmless nonleptonic decay such as the {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup +}{pi}{sup {minus}}, {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup +}{rho}{sup {minus}}, {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup *+}{pi}{sup {minus}} decays, which include contributions from both Born process and penguin process, in the standard model. The branching ratios of these three decays are predicted to be {similar to}10{sup {minus}5}, {similar to}10{sup {minus}5}--10{sup {minus}6}, and {similar to}10{sup {minus}5}, respectively. For the {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup +}{pi}{sup {minus}} decay, the amplitude is dominated by the timelike penguin process. For the {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup +}{rho}{sup {minus}} decay, the dominant amplitude follows from the spacelike penguin process, which is ambiguous due to the annihilation form factor. For the {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup *+}{pi}{sup {minus}} decay, the contributions of the three processes are comparable to each other. The precise determination of the annihilation form factor is necessary to predict reliably the branching ratios of the {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup +}{rho}{sup {minus}} and {ital B}{sub {ital d}}{sup 0}{r arrow}{ital K}{sup *+}{pi}{sup {minus}} decays.
