Abstract
We present results of searches for B-meson decays to K(+)pi(-)pi(+) with the BABAR detector. With a data sample of 61.6x10(6) B (B) over bar pairs, we measure the branching fractions and 90% confidence-level upper limits averaged over charge-conjugate states (the first error is statistical and the second is systematic): B[B+-->K-*0(892)pi(+)]=(15.5+/-1.8(-4.0)(+1.5))x10(-6), B[B+-->f(0)(980)K+,f(0)-->pi(+)pi(-)]=(9.2+/-1.2(-2.6)(+2.1))x10(-6), B[B+-->(D) over bar (0)pi(+),(D) over bar (0)-->K(+)pi(-)]=(184.6+/-3.2+/-9.7)x10(-6), B[B+-->rho(0)(770)K+]<6.2x10(-6) and B[B+-->K(+)pi(-)pi(+)nonresonant]<17x10(-6).File in questo prodotto:
