Available in PDF, EPUB and Kindle. Book excerpt: The KTeV E799 experiment has conducted a search for the rare decays KL2!0?0æ+æ- and KL2!0?0X02!?0?0æ+æ-, where the X0 is a possible new neutral boson that was reported by the HyperCP experiment with a mass of (214.3 ± 0.5) MeV/c2. We find no evidence for either decay. We obtain upper limits of Br(KL2!0?0X0 2!?0?0æ+æ-) 1.0 x 10sup-10/sup and Br(KsubL/sub2!?sup0/sup?sup0/supæsup+/supæsup-/sup) 9.2 x 10sup-11/sup at the 90% confidence level. This result rules out the pseudoscalar Xsup0/sup as an explanation of the HyperCP result under the scenario that the ds̄X

Book excerpt: We present a search for the rare decays B → K+?{bar?} and B° → K°?{bar?} using 459 million B{bar B} pairs collected with the BABAR detector at the SLAC National Accelerator Laboratory. Flavor-changing neutral-current decays such as these are forbidden at tree level but can occur through one-loop diagrams in the Standard Model (SM), with possible contributions from new physics at the same order. The presence of two neutrinos in the final state makes identification of signal events challenging, so reconstruction in the semileptonic decay channels B → D{sup (*)}l? of the B meson recoiling from the signal B is used to suppress backgrounds. We set an upper limit at the 90% confidence level of 1.3 x 10−5 on the total branching fraction for B+ → K+?{bar {nu}}, and 5.6 x 10−5 for B° → K°{nu}{bar {nu}}. We additionally report partial branching fractions in two ranges of di-neutrino mass squared for B+ → K+{nu}{bar {nu}}.

Book excerpt: This thesis describes a search for the rare radiative decay B0 → ??, 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.
