This book was released on 2011 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This article reports a measurement of the cross section of prompt isolated photon pair production in p{bar p} collisions at a total energy √s = 1.96 TeV using data of 5.36 fb−1 integrated luminosity collected with the CDF II detector at the Fermilab Tevatron. The measured cross section, differential in basic kinematic variables, is compared with three perturbative QCD predictions, a leading order (LO) parton shower calculation and two next-to-leading order (NLO) calculations. The NLO calculations reproduce most aspects of the data. By including photon radiation from quarks before and after hard scattering, the parton shower prediction becomes competitive with the NLO predictions.

Available in PDF, EPUB and Kindle. Book excerpt: Here, we describe a measurement of the ratio of the cross sections times branching fractions of the Bc+ meson in the decay mode Bc+ → J/[psi][mu]+[nu] to the B+ meson in the decay mode B+ → J/[psi]K+ in proton-antiproton collisions at center-of-mass energy √s = 1.96 TeV. The measurement is based on the complete CDF Run II data set, which comes from an integrated luminosity of 8.7 fb-1. The ratio of the production cross sections times branching fractions for Bc+ and B+ mesons with momentum transverse to the beam greater than 6 GeV/c and rapidity magnitude smaller than 0.6 is 0.211 ± 0.012(stat)-0.020+0.021(syst). Using the known B+ → J/[psi]K+ branching fraction, the known B+ production cross section, and a selection of the predicted Bc+ → J/[psi][mu]+[nu] branching fractions, the range for the total Bc+ production cross section is estimated.

Download or read book The Diphoton Production Rate in {bar P}p Collisions at (square Root)s written by and published by . This book was released on 1994 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A measurement of the rate of prompt diphoton production in {bar p}p collisions at (square root)s = 1800 GeV using the CDF detector is presented. The background from non-prompt sources is estimated using a sample of single photon candidate events. The results are compared to a next-to-leading order calculation by Bailey, et al. Both background and signal take on particular significance as an indicator of our ability to estimate the backgrounds affecting LHC low mass Higgs to diphoton searches.

This book was released on 2004 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the measurement of prompt diphoton production rate in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV using the upgraded Collider Detector at Fermilab (CDF II). This process deserves some attention for the following reasons. The H → ?? decay mode is an important channel for the Standard Model (SM) Higgs boson searches in the low mass region (MH 130 GeV) at the forth coming LHC. In many models involving physics beyond the SM, cascade decays of heavy new particles generate a ?? signature. Some examples are supersymmetry with a light gravitino, radiative decays to a higgsino-LSP and models with large symmetry groups. The QCD production of prompt photon pairs with large invariant mass is the irreducible background to these searches. The rate is huge and requires to be quantitatively evaluated prior to any of the possible discoveries. In a hadronic collider environment such as LHC, prompt photon signals are contaminated by the production of neutral mesons which decay to multiple collinear photons. The experience of classifying background of neutral meson is very important. The process can be used to test the Next-to-Leading Order (NLO) calculation of Quantum Chromodynamics (QCD). The 4-momentum of particles in the di-photon final state can be precisely determined due to the fine energy resolution of the electromagnetic calorimeters. The imbalance in the transverse momentum of the two photons reflects the transverse motion of the colliding partons. At collider energies, most of the transverse momentum of the incoming partons can be attributed to multiple soft gluon emissions prior to the collision, of which the effect to di-photon production can be resummed by Collins-Soper-Sterman (CSS) formalism. The Tevatron data can be used to test the resummation formalisms. They have used 207 pbsup-1
