Book Description
A search for the exclusive radiative decays B[yields][rho](770)[gamma] and B[sup 0][yields][omega](782)[gamma] is performed on a sample of about 84 million B[bar B] events collected by the BABAR detector at the PEP-II asymmetric-energy e[sup+]e[sup -] storage ring. No significant signal is seen in any of the channels. We set upper limits on the branching fractions[Beta] of[Beta](B[sup 0][yields][rho][sup 0][gamma])

Book Description
Results from the BABAR experiment are presented for searches for several rare FCNC B and D meson decays, including the modes B{sup 0} {yields} {ell}{sup +}{ell}{sup -} and D{sup 0} {yields} {ell}{sup +}{ell}{sup -}, B {yields} ({rho}, {omega}){gamma} and B{sup +} {yields} (K, {pi}){sup +}{nu}{bar {nu}}. Limits on lepton flavor violation in neutrino-less {tau} decays are also discussed. Finally, results of BABAR searches for the strange pentaquark states {Theta}{sup +}(1540), {Xi}{sup --}(1860) and {Xi}{sup 0}(1860) are summarized.

Book Description
Measurements and searches for rare B decays have been performed with the BaBar detector at the PEP-II e[sup +]e[sup -] asymmetric B Factory, operating at the [Upsilon](4S) resonance. The authors report some recent branching fraction measurements on hadronic and radiative B decays, occurring from b --> s/d and b --> u transitions. Most of the results presented here are based on a data sample corresponding to a luminosity of 81.9 fb[sup -1].

Book Description
Observational evidence and theoretical motivation have led us to the conclusion that our current understanding of the universe is incomplete. While new physics is expected to exist above the electroweak scale, its influence can be detected by experiments that operate below this scale. The Babar experiment has recorded approximately 432 fb-1 of data at the center of mass energy of 10.58 GeV, which corresponds to the Y(4S) mass. One of the physics programs is studying radiative decays of the B meson. These decays primarily proceed through loop diagrams, and thus influences of new particles may be detectable. In this thesis, I present results of the measurements of the branching fractions, CP asymmetry, and isospin asymmetry of B -> K* gamma. Results are also presented for the measurements of the branching fractions of B -> rho(omega) gamma. Finally, a search for the decay of B -> phi gamma is given.

Book Description
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]
