Available in PDF, EPUB and Kindle. Book excerpt: The authors present results of searches for B-meson decays to K[sup+][pi][sup -][pi][sup+] with the BABAR detector. With a data sample of 61.6 million B[bar B] pairs, they 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):[Beta](B[sup+][yields] K*[sup 0](892)[pi][sup+])= (15.5[+-] 1.8[sub -4.0][sup+1.5]) x 10[sup -6], [Beta](B[sup+][yields] f[sub 0](980)K[sup+], f[sub 0][yields][pi][sup+][pi][sup -])= (9.2[+-] 1.2[sub -2.6][sup+2.1]) x 10[sup -6], [Beta](B[sup+][yields][bar D][sup 0][yields] K[sup+][pi][sup -])= (184.6[+-] 3.2[+-] 9.7) x 10[sup -6], [Beta](B[sup+][yields][rho][sup 0](770)K[sup+])
