This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A search for the decays B --> [rho](770)[gamma] and B[sup 0] --> [omega](782)[gamma] is performed on a sample of 211 million [Upsilon](4S) --> B[bar B] events collected by the BABAR detector at the PEP-II asymmetric-energy e[sup +]e[sup -] storage ring. No evidence for the decays is seen. The authors set the following limits on the individual branching fractions B(B[sup +] --> [rho][sup +][gamma]) 1.8 x 10[sup -6], B(B[sup 0] -- [rho][sup 0][gamma]) 0.4 x 10[sup -6], and B(B[sup 0] -- [omega][gamma]) 1.0 x 10[sup -6] at the 90% confidence level (C.L.). They use the quark model to limit the combined branching fraction [bar B]B -- ([rho]/[omega])[gamma]
