Book excerpt: We present a search for the rare radiative decay W{sup {+-}} →?{sup {+-}}? using data corresponding to an integrated luminosity of 4.3 fb−1 of proton-antiproton collisions at a center of mass energy of 1.96 TeV collected by the CDF experiment at Fermilab. As no statistically significant signal is observed, we set a 95% confidence level upper limit on the relative branching fraction?(W{sup {+-}} →?{sup {+-}}?)/?(W{sup {+-}} → e{sup {+-}}?) at 6.4 x 10−5, a factor of 10 improvement over the previous limit.

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: The authors study on the rare decay K{sub L} 2![pi]°[gamma][gamma], measure a{sub V}, and branching ratio by analyzing 96, 97 and 99 data. The measurements were taken by KTeV at Fermi National Accelerator Laboratory. After all cuts, they have 1982 K{sub L} 2![pi]°[gamma][gamma] candidate. The background level is estimated as 30%. K{sub L} 2![pi]°[gamma][gamma] branching ratio is measured as (1.29 ± 0.03(stat) ± 0.04(sys)) x 10−6. By using D'Ambrosio's theory to fit a{sub V}, a{sub V} = -( -0.31 ± 0.05(stat) ± 0.07(sys)).

Available in PDF, EPUB and Kindle. Book excerpt: This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

Available in PDF, EPUB and Kindle. Book excerpt: The radiative pion decay .pi. .-->. ee−e+.nu. has been observed for the first time with a branching ratio of (3.4 +- 0.5) x 10−9. From the kinematical distribution of 79 events information on the form factors was extracted. The vector form factor F/sub V/ was found to have the same sign as the pion decay constant f/sub .pi./. For the axial-vector form factors the following values have been measured: .gamma. = F/sub A//F/sub V/ = 0.7 +- 0.5 and xi = R/F/sub V/ = 2.3 +- 0.6. This value of .gamma. agrees well with the small positive value of (0.53 +- 0.06) and excludes the large negative value obtained in .pi.+ .-->. e+.nu gamma. experiments. 8 refs. 8 refs.
