Book excerpt: An experimental search for the lepton-family number nonconserving decay, .mu. .-->. e.gamma gamma., has been conducted at the Clinton P. Anderson Meson Physics Facility (LAMPF) using the Crystal Box detector. The detector consists of a modular NaI(Tl) calorimeter, scintillator hodoscope, and a high-resolution, cylindrical drift chamber. It provides a large solid-angle for detecting three-body decays and has good resolutions in the time, position, and energy measurements to eliminate unwanted backgrounds. No evidence for .mu.+ .-->. e+.gamma gamma. is found, giving an upper limit for the branching ratio of GAMMA(.mu. .-->. e.gamma gamma.)/GAMMA(.mu. .-->. e nu anti nu) less than or equal to 7.2 x 10−11 (90% C.L.). This result is an improvement of more than two orders of magnitude in the existing limit. 109 refs., 39 figs.

Data- taking is complete, with 450 million events on tape taken over approximately 10[sup 7] seconds. A small portion of the data sample has been processed through the complete event reconstruction codes to search for the [mu] [yields] [ital e][gamma] process. No evidence for the [mu] [yields] [ital e][gamma] decay is observed at a sensitivity of [approximately]7 x 10[sup -11] (90% confidence).

This book was released on 2012 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The MEG experiment is the latest in a series of progressively more precise rare decay searches designed to exploit an observation of [mu]+[superscript] [arrow right] e+[superscript] [gamma] or lack thereof as a sensitive low energy probe of new physics. A search for [mu]+[superscript] [arrow right] e+[superscript] [gamma] is performed using the 43 days worth of data acquired by the MEG experiment during 2009. To best estimate the number of signal events in the data, a maximum likelihood fit is performed. A 90% confidence interval is then constructed using the Feldman-Cousins technique. The analysis is done blind by hiding signal-like events until the selection cuts and likelihood function are settled upon. The result is consistent with the null hypothesis and an upper limit is set: BR([mu]+[superscript] [arrow right] e+[superscript] [gamma]

Book excerpt: An innovative and state of the art pair spectrometer system to measure the photon component of [mu][sup +] decay to obtain an improved branching ratio limit for the decay [mu] [yields] e[gamma] is investigated. Analysis algorithms are developed and an experimental inner bremsstrahlung spectrum is obtained and agrees well with Monte Carlo simulations. Background sources are investigated and found to be highly suppressed at various stages of acquisition and analysis.

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])

Book excerpt: This thesis describes a search for the rare radiative decay B0 → [gamma][gamma], where the charged congugate mode is implied throughout. These decays are highly suppressed in the Standard Model where the branching fraction is expected to be of order 10-8. In some new physics scenarios this could be enhanced by up to an order of magnitude to 10-7. Therefore an observation of a significant signal above the Standard Model prediction could be a sign of new physics.

Available in PDF, EPUB and Kindle. Book excerpt: Using the Stopped Muon Channel at LAMPF to produce a surface muon beam, 2.3 x 1012 muons were stopped in a 50 mg/cm2 target. The solid angle-efficiency product of the detector for the rare decay .mu. .-->. e.gamma. was 1.2%. Hence, 3 x 101° .mu./sup +/ decays were examined. There is no indication of any signal, the data being consistent with a small background of random electron and gamma coincidences. The new upper limit on the branching ratio is GAMMA(.mu./sup +/ .-->. e/sup +/.gamma.)/GAMMA(.mu./sup +/ .-->. e/sup +/.nu./sub e/.nu.−/sub mu/)
