Book Synopsis Measurements of B -] V Gamma Decays by : Aaron Kevin Yarritu
Download or read book Measurements of B -] V Gamma Decays written by Aaron Kevin Yarritu and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2006 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present measurements of the B {yields} {eta}K{gamma} branching fractions and upper limits for the B {yields} {eta}'K{gamma} branching fractions. For B{sup +} {yields} {eta}K{sup +}{gamma} they also measure the time-integrated charge asymmetry. The data sample, collected with the BABAR detector at the Stanford Linear Accelerator Center, represents 232 x 10{sup 6} produced B{bar B} pairs. The results for branching fractions and upper limits at 90% C.L. in units of 10{sup -6} are: {Beta}(B{sup 0} {yields} {eta}K{sup 0}{gamma}) = 11.3{sub -2.6}{sup +2.8} {+-} 0.6, {Beta}(B{sup +} {yields} {eta}K{sup +}{gamma}) = 10.0 {+-} 1.3 {+-} 0.5, {Beta}(B{sup 0} {yields} {eta}'K{sup 0}{gamma})
