This book was released on 2009 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Standard Model is the best current description of fundamental interactions and particles; however, the Standard Model has certain shortcomings which have driven particle physicists for the last 30 years to search for phenomena which provide evidence for the next theory beyond the Standard Model. To this end, using the BaBar detector, we search for evidence of the rare decay D* -> D0[pi];D0->[gamma][gamma]. The branching fraction of this decay is enhanced up to 200 times the standard model prediction in certain beyond-the-Standard-Model theories. A measurement of a significant branching fraction would provide evidence for a new theory of particle physics. We describe our search for this rare decay and an improved measurement of the associated decay, B(D0-> [pi]0 [pi]0) using an integrated luminosity corresponding to 470.5 fb−1 of e e− data collected by the BaBar detector at the PEP-II asymmetric ee− collider at SLAC from 1999-2007. We place an upper limit of B(D0->[gamma][gamma]) 2.51 X 10−6 at 90% confidence level and find B(D0-[pi]0[pi]0) = (8.4 " 0.1 " 0.4 " 0.3) X 10−4.

Book Synopsis Search for B0 Decays to Invisible Final States and to Nu Nubar Gamma by :
Download or read book Search for B0 Decays to Invisible Final States and to Nu Nubar Gamma written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We establish upper limits on branching fractions for B[sup 0] decays to final states where the decay products are purely invisible (i.e., no observable final state particles) and for B[sup 0] decays to [nu][bar [nu]][gamma]. Within the Standard Model, these decays have branching fractions that are below current experimental sensitivity, but various models of physics beyond the Standard Model predict significant contributions from these channels. Using 88.5 million B[bar B] pairs collected at the [Upsilon](4S) resonance by the BABAR experiment at the PEP-II e[sup +]e[sup -] storage ring at the Stanford Linear Accelerator Center, we establish upper limits at the 90% confidence level of 22 x 10[sup -5] for the branching fraction of B[sup 0] [yields] invisible and 4.7 x 10[sup -5] for the branching fraction of B[sup 0] [yields] [nu][bar [nu]][gamma].

Download or read book A Search for the Rare Decay $B\rightarrow\gamma\gamma$ written by and published by . This book was released on 2011 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the result of a search for the rare decay B° 2![gamma][gamma] in 426 fb−1 of data, corresponding to 226 million B°{bar B}° pairs, collected on the [Upsilon](4S) resonance at the PEP-II asymmetric-energy ee− collider using the BABAR detector. We use a maximum likelihood fit to extract the signal yield and observe 2112{sup +13} signal events with a statistical signficance of 1.9 [sigma]. This corresponds to a branching fraction [Beta](B° 2![gamma][gamma]) = (1.7 ± 1.1(stat.) ± 0.2(syst.)) x 10−7. Based on this result, we set a 90% confidence level upper limit of [Beta](B° 2![gamma][gamma])
