Abstract
We present a measurement of the partial branching fractions and mass spectra of the exclusive radiative penguin processes B -> K pi pi gamma in the range m(K pi pi)< 1.8 GeV/c(2). We reconstruct four final states: K+pi(-)pi(+)gamma, K+pi(-)pi(0)gamma, K-S(0)pi(-)pi(+)gamma, and K-S(0)pi(+)pi(0)gamma, where K-S(0)->pi(+)pi(-). Using 232x10(6) e(+)e(-)-> B (B) over bar events recorded by the BABAR experiment at the SLAC PEP-II asymmetric-energy storage ring, we measure the branching fractions B(B+-> K+pi(-)pi(+)gamma)=[2.95 +/- 0.13(stat)+/- 0.20(syst)]x10(-5), B(B-0 -> K+pi(-)pi(0)gamma)=[4.07 +/- 0.22(stat)+/- 0.31(syst)]x10(-5), B(B-0 -> K-0 pi(+)pi(-)gamma)=[1.85 +/- 0.21(stat)+/- 0.12(syst)]x10(-5), and B(B+-> K-0 pi(+)pi(0)gamma)=[4.56 +/- 0.42(stat)+/- 0.31(syst)]x10(-5).
