Available in PDF, EPUB and Kindle. Book excerpt: Using 8.5M BB events recorded by the BABAR detector the yield of inclusive J[psi], the branching ratios of [psi](2S) and x{sub c} are presented. Combining the charmonium state with either a K{sup +-}, K{sub s}°, K*{sup +-} exclusive B decays are reconstructed and their branching ratios determined. Using the fully reconstructed decays, both the B° B{sup +-} masses and their difference is measured. Finally the contributions of CP even and odd amplitudes in the decay B → J/[psi] K* are determined from an angular analysis.

Book excerpt: A wealth of new measurements of hadronic B decays to open charm and charmonium have been performed on the data sample collected by the BaBar experiment at the PEP-II e{sup +}e{sup -} B-factory. We report the first measurement of the rates for inclusive charm production separately for charged and neutral B mesons. Combining measurements of the decay rate of B{sup 0} {yields} D*{sub s}{sup +}D*{sup -} obtained with a partial reconstruction technique and the complete reconstruction of B{sup 0} {yields} D*{sub s}{sup +}D*{sup -} with D{sub s}{sup +} {yields} {phi}{pi}{sup +}, we obtain the most precise measurement of {Beta}(D{sub s}{sup +} {yields} {phi}{pi}{sup +}). We present an update of the measurements of the branching fractions of exclusive B decays to J/{psi}, {psi}(2S), {chi}{sub c1}, {chi}{sub c2} and a kaon or a K*. In addition, we show preliminary results on exclusive decay rates to final states with baryons, or newly-discovered particles, such as D*{sub sJ}(2317), D{sub sJ}(2460){sup +}, and the X(3872).

Book Synopsis Measurements of the X c and X b Quarkonium States in pp Collisions with the ATLAS Experiment by : Andrew Chisholm
Download or read book Measurements of the X c and X b Quarkonium States in pp Collisions with the ATLAS Experiment written by Andrew Chisholm and published by Springer. This book was released on 2015-09-14 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis, which won one of the six 2015 ATLAS Thesis Awards, concerns the study of the charmonium and bottomonium bound heavy quark bound states. The first section of the thesis describes the observation of a candidate for the chi_b(3P) bottomonium states. This represented the first observation of a new particle at the LHC and its existence was subsequently confirmed by D0 and LHCb experiments. The second part of the thesis presents measurements of the prompt and non-prompt production of the chi_c1 and chi_c2 charmonium states in proton-proton collisions. These measurements are compared to several theoretical predictions and can be used to inform the development of theoretical models of quarkonium production.

Book Synopsis Inclusive Semileptonic B Decays at BABAR. by :
Download or read book Inclusive Semileptonic B Decays at BABAR. written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report updates on two analyses of inclusive semileptonic B decays based on a dataset of 89 million B[bar B] events recorded with the BABAR detector at the [Upsilon](4S) resonance. Events are selected by fully reconstructing the decay of one B meson and identifying a charged lepton from the decay of the other [bar B] meson. IN the first analysis, the measurement of the first and second moment of the hadronic mass distribution in Cabibbo-favored [bar B] [yields] X[sub c][ell][bar [nu]] decays allows for the determination of the nonperturbative parameters [bar [Lambda]] and [lambda][sub 1] of Heavy Quark Effective Theory (HQET) and V[sub cb]. In the second analysis, the hadronic mass distribution is used to measure the inclusive charmless semileptonic branching fraction and to determine V[sub ub].
Book Synopsis Flavor Physics, Proceedings Of Icfp2001 by : Yue-liang Wu
Download or read book Flavor Physics, Proceedings Of Icfp2001 written by Yue-liang Wu and published by World Scientific. This book was released on 2002-05-14 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains many excellent articles presenting the most recent progress in high energy physics and the current interesting problems concerning flavor physics. The reader will see how flavor physics has become a central area of particle physics, with the Standard Model (SM) being subjected to increasingly precise experiments, and why the remaining puzzles in the SM, such as the mechanisms of symmetry breaking and CP violation, as well as fermion mass and mixing generation, all are mysteries hidden in the physics of flavor. The book also shows that flavor physics is likely to be a window for probing new physics beyond the SM for many years to come.
