Available in PDF, EPUB and Kindle. Book excerpt: The decay width and mass of the D{sub s1}(2536) meson are measured via the decay channel D{sub s1}+ 2!D*+ K{sub S}° using 385 fb−1 of data recorded with the BABAR detector in the vicinity of the [Upsilon](4S) resonance at the PEP-II asymmetric-energy electron-positron collider. The result for the decay width is [Gamma](D{sub s1}+) = 0.92 ± 0.03 (stat.) ± 0.04 (syst.)MeV. For the mass, a value of m(D{sub s1}+) = 2535.08 ± 0.01 (stat.) ± 0.15 (syst.)MeV/c2 is obtained. The mass difference between the D{sub s1}+ and the D*+ is measured to be m(D{sub s1}+)-m(D*+) = 524.83 ± 0.01 (stat.) ± 0.04 (syst.)MeV/c2, representing a significant improvement compared to the current world average. The unnatural spin-parity assignment for the D{sub s1}+ meson is confirmed.

Available in PDF, EPUB and Kindle. Book excerpt: The decay width and the mass of the D{sub s1}(2536){sup {+-}} have been measured via the decay channel D{sub s1}{sup {+-}} {yields} D*{sup {+-}}K{sub S}{sup 0} using 232 fb{sup -1} of data collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage ring. The result for the decay width is {Lambda}(D{sub s1}{sup {+-}}) = (1.03 {+-} 0.05 {+-} 0.12) MeV/c{sup 2}, with the first error denoting the statistical uncertainty and the second one the systematic uncertainty. For the mass, a value of m(D{sub s1}{sup {+-}}) = (2534.85 {+-} 0.02 {+-} 0.40) MeV/c{sup 2} has been obtained. The systematic error is dominated by the uncertainty on the D*{sup {+-}} mass. The mass difference between the D{sub s1}{sup {+-}} and D*{sup {+-}} has been measured to be {Delta}m = (524.85 {+-} 0.02 {+-} 0.04) MeV/c{sup 2}.

Book excerpt: The mass m[sub [eta][sub c]] and total width [Lambda][sub tot][sup [eta][sub c]] of the [eta][sub c] meson have been measured in two-photon interactions at the SLAC e[sup +]e[sup -] asymmetric B-Factory with the BABAR detector. With a sample of approximately 2500 reconstructed [eta][sub c] [yields] K[sub S][sup 0]K[sup [+-]] [pi][sup [-+]] decays in 88 fb[sup -1] of data, the results are m[sup [eta][sub c]] = 2982.5 [+-] 1.1 (stat) [+-] 0.9 (syst) MeV/c[sup 2] and [Lambda][sub tot][sup [eta][sub c]] = 34.3 [+-] 2.3 (stat) [+-] 0.9 (syst) MeV/c[sup 2]. Using the same decay mode, a second resonance with 112 [+-] 24 events is observed with a mass of 3630.8 [+-] 3.4 (stat) [+-] 1.0 (syst) MeV/c[sup 2] and width of 17.0 [+-] 8.3 (stat) [+-] 2.5 (syst) MeV/c[sup 2]. This observation is consistent with expectations for the [eta][sub c](2S) state.

Ten other sections have been substantially revised, with some, such as the Table of the Isotopes and Thermal Conductivity of Liquids, significantly expanded. The Fundamental Physical Constants section has been updated with the latest CODATA/NIST values, and the Mathematical Tables appendix now features several new sections covering topics that include orthogonal polynomials Clebsch-Gordan coefficients, and statistics.

Available in PDF, EPUB and Kindle. Book excerpt: In a sample of 58 million J/[psi] events collected with the BES II detector, the process J/[psi][yields][gamma][eta][sub c] is observed in five different decay channels:[gamma] K[sup+] K[sup -][pi][sup+][pi][sup -][pi][sup+][pi][sup -], [gamma]K[sup[+-]] K[sub S][sup 0][pi][sup[-+]] (with K[sub S][sup 0][yields][pi][sup+][pi][sup -]), [gamma][phi][phi] (with[phi][yields] K[sup+]K[sup -]) and[gamma]p[bar p]. From a combined fit of all five channels, they determine the mass and full-width of[eta][sub c] to be m[sub[eta][sub c]]= 2977.5[+-] 1.0 (stat.)[+-] 1.2 (syst.) MeV/c[sup 2] and[Lambda][sub[eta][sub c]]= 17.0[+-] 3.7 (stat.)[+-] 7.4 (syst.) MeV/c[sup 2].

Book Synopsis A Personal History of CESR and CLEO by : Karl Berkelman
Download or read book A Personal History of CESR and CLEO written by Karl Berkelman and published by World Scientific. This book was released on 2004 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book is a historical account of the Cornell Electron Storage Ring and its main detector facility, CLEO, from their beginnings in the late 1970's until the end of data collection at particle energies above the threshold for B meson production in June 2001. The CESR electron-positron collider was the culmination of a series of electron accelerators constructed at the Cornell Laboratory of Nuclear Studies, starting in 1945. Measurement of the products of the e+e- collisions was performed with the multipurpose CLEO apparatus, built and operated by the CLEO collaboration, which consisted of about 200 faculty, staff and graduate students from over 20 universities. This account is based mainly on the author's recollections as a participant.
Download or read book SCADRON70 written by G. Rupp and published by American Institute of Physics. This book was released on 2008-07-22 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The light scalar mesons have been posing serious problems to both theorists and experimentalists. Even nowadays there is no consensus whatsoever on the quark structure of these hadronic resonances, some of which are very broad. Nevertheless, the light scalars are of tremendous importance for a better understanding of QCD and strong interactions, with far-reaching implications for nuclear physics as well. The SCADRON70 Workshop managed to bring together many of the leading experts in the field, with invited talks of spokespersons of practically all major experimental collaborations in particle and hadronic physics, besides invited talks given by some renowned theorists. Simultaneously, the Workshop allowed to honor one of the pioneers of scalar mesons, viz. Prof. Michael D. Scadron, at the occasion of his 70th birthday.

Book Synopsis Hadron Spectroscopy by : Eberhard Klempt
Download or read book Hadron Spectroscopy written by Eberhard Klempt and published by American Institute of Physics. This book was released on 2004-09-13 with total page 1006 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main topic of the conference was the physics of strong interaction and the understanding of how quarks form hadrons, which are part of the atomic nucleus. The proceedings give a comprehensive overview of the present status of the physics of hadrons. Topics include: mesons, baryons, scalars, exotics, heavy quarks, theoretical concepts, hadrons in matter, and reactions. The timing of the conference was very fortunate as many new and surprising results appeared in the months before its start. The highlights were the discussions about the nature of the recently discovered arrow states.
