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: The authors report evidence for the decays B° → D{sub s}?− and B° → D{sub s}− K+ and the results of a search for B° → D{sub s}+?− and B° → D{sub s}− K+ in a sample of 84 million?(4S) decays into B{bar B} pairs collected with the BABAR detector at the PEP II asymmetric-energy e+e− storage ring. The authors measure the branching fractions?(B° → D{sub s}+?−) = (3.2 ± 0.9(stat.) ± 1.0(syst.)) x 10−5 and?(B° → D{sub s}− K+) = (3.2 ± 1.0(stat.) ± 1.0(syst.)) x 10−5.

Book excerpt: The high cross-section for the production of b quarks at the Tevatron hadron collider make it an ideal place to search for rare B meson species and very low branching fraction decay modes of the more common B mesons. This paper reports the recent discovery of the Bc meson by the CDF collaboration. It also discusses the observation of rare B meson final states involving?(2S) mesons and searches for ultra-rare decays such as B 2!??−

Book excerpt: I review the status and future prospects of searches for forbidden and highly kaon suppressed decays. This workshop comes as we are poised at the threshold of a new generation of rare K decay experiments. There are new experiments running or about to run at KEK, BNL, FNAL, and CERN. In another year or so these will be joined by the KLOE experiment at DA[Phi]NE. The good news is that it's a very exciting time. The bad news, at least for a reviewer, is that there aren't too many new results. Thus I'll be giving a little more attention than usual to what the experimenters expect to do. My discussion of rare K decays covers processes that are forbidden in the Standard Model, those that highly suppressed and to a smaller extent, those that are merely discouraged.
