This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the process ee− 2!?+?−?+?−?, with a hard photon radiated from the initial state. About 60,000 fully reconstructed events have been selected from 89 fb−1 of BABAR data. The invariant mass of the hadronic final state defines the effective e+e− center-of-mass energy, so that these data can be compared with the corresponding direct e+e− measurements. From the 4?-mass spectrum, the cross section for the process e+e− 2!?+?−?+?− is measured for center-of-mass energies from 0.6 to 4.5 GeV. The uncertainty in the cross section measurement is typically 5%. We also measure the cross sections for the final states K+K−?+− and K+K−K+K−. We observe the J/? in all three final states and measure the corresponding branching fractions. We search for X(3872) in J/?(2!?+?−)?+?− and obtain an upper limit on the product of the e+e− width of the X(3872) and the branching fraction for X(3872) 2!J/??+?−.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: First results of a study of the ee− → ?+?−?+?−? process with hard photon emitted from initial state are presented. About 60000 fully reconstructed events have been selected based on 89.3 fb−1 of BABAR data. The invariant mass of the hadronic final state defines the effective collision c.m. energy, and so BABAR ISR data can be compared to the relevant direct e+e− measurements. From obtained 4? mass spectrum we evaluate e+e− → ?+?−?+?− cross section for the range of c.m.s. energy from 0.6 to 4.5 GeV. The systematic error of the cross section measurement is 5% and comparable with the best e+e− data. The cross sections for identified 2K2? and 4K final states also have been presented.

Aubert and published by . This book was released on 2006 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the processes e{sup +}e{sup -} {yields} 3({pi}{sup +}{pi}{sup -}){gamma}, 2({pi}{sup +}{pi}{sup -}{pi}{sup 0}){gamma} and K{sup +}K{sup -} 2({pi}{sup +} {sup -}){gamma}, with the photon radiated from the initial state. About 20,000, 33,000 and 4,000 fully reconstructed events, respectively, have been selected from 232 fb{sup -1} of BABAR data. The invariant mass of the hadronic final state defines the effective e{sup +}e{sup -} center-of-mass energy, so that these data can be compared with the corresponding direct e{sup +}e{sup -} measurements. From the 3({pi}{sup +}{pi}{sup -}), 2({pi}{sup +}{pi}{sup -}{pi}{sup 0}) and K{sup +}K{sup -} 2({pi}{sup +}{pi}{sup -}) mass spectra, the cross sections for the processes e{sup +}e{sup -} {yields} 3({pi}{sup +}{sup -}), e{sup +}e{sup -} {yields} 2({pi}{sup +}{pi}{sup -}{pi}{sup 0}) and e{sup +}e{sup -} {yields} K{sup +}K{sup -} 2({pi}{sup +}{pi}{sup -}) are measured for center-of-mass energies from production threshold to 4.5 GeV. The uncertainty in the cross section measurement is typically 6-15%. We observe the J/{psi} in all these final states and measure the corresponding branching fractions.

This book was released on 2011 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the processes ee− 2!K+K−?+?-?, K+K−?°?°?, and K+K−K+K−?, where the photon is radiated from the initial state. About 84000, 8000, and 4200 fully reconstructed events, respectively, are selected from 454 fb−1 of BABAR data. The invariant mass of the hadronic final state defines the e+e− center-of-mass energy, so that the K+K−?+?−? data can be compared with direct measurements of the e+e− 2!K+K−?+?− reaction. No direct measurements exist for the e+e− 2!K+K−?°?° or e+e− 2!K+K−K+K− reactions, and we present an update of our previous result with doubled statistics. Studying the structure of these events, we find contributions from a number of intermediate states, and extract their cross sections. In particular, we perform a more detailed study of the e+e− 2!?(1020)??? reaction, and confirm the presence of the Y (2175) resonance in the?(1020)f0(980) and K+K− f0(980) modes. In the charmonium region, we observe the J/? in all three final states and in several intermediate states, as well as the?(2S) in some modes, and measure the corresponding branching fractions.

This book was released on 2007 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the processes e+e− → K+K−?+?−?, K+K−?°?°? and K+K−K+K−?, where the photon is radiated from the initial state. About 34600, 4400 and 2300 fully reconstructed events respectively, are selected from 232 fb−1 of BABAR data. The invariant mass of the hadronic final state defines the effective e+e− center-of-mass energy, so that the K+K−?+?−? data can be compared with direct measurements of the e+e− → K+K−?+?−? reaction; no direct measurements exist for the e+e− → K+K−?°?°? or e+e− → K+K−K+K− reactions. Studying the structure of these events, we find contributions from a number of intermediate states, and we extract their cross sections where possible. In particular, we isolate the contribution from e+e− → ?(1020)f0(980) and study its structure near threshold. In the charmonium region, we observe the J/? in all three final states and several intermediate states, as well as the ?/(2S) in some modes, and measure the corresponding branching fractions. We see no signal for the Y(4260) and obtain an upper limit of ?{sub Y(4260)→??+?−} · ?{sub ee}{sup Y}

Download or read book Comparison of the Differential Cross-sections For. Pi. −p. --]. Eta 'n And. Pi. −p. --]. Eta N at 8. 45 GeV/c written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The ratio R of the differential cross sections for .pi.−p eta'n and .pi.−p eta n was measured with high statistics and small systematic errors at 8.45 GeV/c. R is generally interpreted as the relative content of nonstrange, ground-state quarks in eta' and eta. It is found that R decreases with increasing t; however, extrapolation to t = 0 gives R(0) = 0.672 +- 0.032 (statistical) +- 0.047 (systematic) for the dominant spin flip cross sections, and R(0) = 0.500 +- 0.085 +- 0.035 for the spin nonflip, in excellent agreement with results at higher energy.
