Book excerpt: The D/sub s/ is the lowest-lying pseudoscalar meson containing charm and anti-strange quarks. Evidence for this state was first reported in 1977, although more recent observations disagree with some of the early results. Since 1983 the weakly decaying D/sub s/+ has been observed in many experiments. Relative branching fractions have been measured for many non-leptonic decay modes, including D/sub s/+ 2!??+,??+?+?/sup /minus//, /bar K/*°K+, and f0(975)?+. The absolute branching fractions are estimated in high energy e+e/sup /minus// annihilation from the observed numbers of reconstructed D/sub s/+ decays and the expected D/sub s/+ production cross section. The lowest-lying vector c/bar s/ meson, the D/sub s/*+, has also been seen in its decay to?D/sub s/+. Weak decays of the heavy quark and lepton flavors are relevant to the development of the Standard Model of both the electroweak and the strong interactions. Measurements of charmed particle weak decay are useful for determining the parameter of the Standard Model and for testing phenomenological models which include strong effects. 83 refs., 56 figs., 12 tabs.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During the running periods of the years 1992, 1993, 1994 the BES experiment at the Beijing Electron Positron Collider (BEPC) collected 22.9[plus-minus] 0.7 pb[sup[minus]1] of data at an energy of 4.03 GeV, which corresponds to a local peak for e[sup+]e[sup[minus]][yields] D[sub s][sup+]D[sub s][sup[minus]] production. Four D[sub s] hadronic decay modes were tagged: D[sub s][yields][phi][pi];[phi][yields] K[sup+]K[sup[minus]]; D[sub s][yields][bar K]*(892)[sup o]K;[bar K]*[sup o](892)[yields] K[sup[minus]][pi][sup+]; D[sub s][bar K][sup o]K;[bar K][sub s][sup o][yields][pi][sup+][pi][sup[minus]]; D[sub s][yields][bar K]*(892)[sup o]K*;[bar K]*[sup o](892)[yields] K[sup[minus]][pi][sup+]; K*(892)[yields] K[sup o][pi][sup+]; K[sub s][sup o][yields][pi][sup+][pi][sup[minus]]. Using the method of double-tagging, BES performed the first model-independent measurement of BrD[sub s[yields][phi][pi]]. Our result was Br[sub D[sub s][yields][phi][pi]]= 3.4[sub[minus]1.7-0.7][sup+4.8+1.3].

Book excerpt: The recent CLEO-c results on hadronic decays of D and D{sub s} mesons are presented. First the absolute branching fractions for D and D{sub s} mesons using a double tag technique are discussed, then are the Cabibbo suppressed decays and doubly Cabibbo suppressed decays. Finally, I present the inclusive and rare decay modes and other measurements from CLEO-c. These decays illuminate a wide range of physics. A brief theoretical introduction is given before the corresponding discussion on measurement.

Book excerpt: This paper describes several outstanding problems in the study of hadronic decays of charmed mesons where further experimental work and theoretical understanding is needed. Four topics are stressed: double Cabibbo suppressed decays (DCSD) of D mesons, hadronic D/sub s/ decays, weak hadronic quasi-two-body decays to pairs of vector mesons, and penguin decays of D mesons. 24 refs., 10 figs., 5 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The e[sup+]e[sup -] annihilation data recorded with the BABAR detector has been used to study B decays to D[sub s][sup (*)[+-]] and D*[sup+-] mesons. The production fraction of inclusive D[sub s][sup (*)[+-]] and the corresponding momentum spectra have been determined. Exclusive decays B[sup 0][yields] D*[sup -] D[sub s][sup (*)+] have been identified with a partial reconstruction technique and their branching fractions have been measured. We also report branching fraction measurements for the exclusive hadronic modes B[sup 0][yields] D*[sup -][pi][sup+] and B[sup 0][yields] D*[sup -][rho][sup+].

Book excerpt: We present preliminary results on hadronic decays of B mesons, based on data recorded at the?(4S) resonance with the BABAR detector at the PEP-II B-factory at SLAC. We measure branching fractions of many B decay modes, including decays to J/??K, J/???− and?{sub c}K final states. We report the observation of the decay B → D{sub s}+?− and the first measurement of the flavor-tagged D meson production in B° decays. Since their preliminary nature, the results presented in this paper are based on different data samples.
