Book Synopsis A Search for New Physics in Photon-lepton Events in Proton-antiproton Collisions At[radical] S by :
Download or read book A Search for New Physics in Photon-lepton Events in Proton-antiproton Collisions At[radical] S written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the results of a search in p[bar p] collisions at[radical]s= 1.8 TeV for anomalous production of events containing a photon with large transverse energy and a lepton (e or[mu]) with large transverse energy, using 86 pb[sup -1] of data collected at the Collider Detector at Fermilab during the 1994-95 collider run at the Fermilab Tevatron. The presence of large missing transverse energy (E[sub T]), additional photons, or additional leptons in these events is also analyzed. The results are consistent with standard model expectations, with the possible exception of photon-lepton events with large E[sub T], for which the probability of a statistical fluctuation of the standard model expectation up to and above the observed level is 0.7%.

Book Synopsis A Study of Four-jet Events and Search for Double Parton Interactions at [radical] by :
Download or read book A Study of Four-jet Events and Search for Double Parton Interactions at [radical] written by and published by . This book was released on 1992 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinematic properties of four-jet events in p[bar p] collisions at [radical]s = 1.8 TeV are compared with the predictions of leading order quantum chromodynamics. We place an upper limit on the double parton scattering cross of [sigma][sub DP] 120 nb (95% C.L.) for partons with transverse momenta greater than 18 GeV/c. Defining the effective cross section [sigma][sub eff] through the equation of [sigma][sub eff] = [sigma][sub DP] = [sigma][sub dijet]/([sup 2]/[sigma][sub eff]), where [sigma][sub dijet] is the cross section for two-jets events, the limit [sigma][sub eff] 3.9 mb (95% C.L.) is also placed. Implications for physics at the SSC ([radical]s = 40 TeV) are discussed.
Book Synopsis Search for Anomalous Production of Photon + Jets + Missing Transverse Energy in $p\bar{p}$ Collisions at $\sqrt{s} by :
Download or read book Search for Anomalous Production of Photon + Jets + Missing Transverse Energy in $p\bar{p}$ Collisions at $\sqrt{s} written by and published by . This book was released on 2011 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: A model-independent signature-based search for physics beyond the Standard Model is performed in the photon~+ jets~+ missing transverse energy channel in \ppbar collisions at a center of mass energy of 1.96 TeV using the CDF II detector. Events with a photon + jets are predicted by the Standard Model and also by many theoretical models beyond the Standard Model. In the Standard Model, the main mechanisms for photon~+ jets production include quark-antiquark annihilation and quark-gluon scattering. No intrinsic missing transverse energy is present in any of these Standard Model processes. In this search, photon~+ $\geq$1 jet and photon~+ $\geq$2 jet events are analyzed with and without a minimum requirement on the missing transverse energy. Numerous mass distributions and kinematic distributions are studied and no significant excess over the background prediction is found. All results indicate good agreement with expectations of the Standard Model.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Samples of inclusive [gamma] + 2 jet and [gamma] + 3 jet events collected by the D0 experiment with an integrated luminosity of about 1 fb−1 in p{bar p} collisions at √s = 1.96 TeV are used to measure cross sections as a function of the angle in the plane transverse to the beam direction between the transverse momentum (p{sub T}) of the [gamma] + leading jet system (jets are ordered in p{sub T}) and p{sub T} of the other jet for [gamma] + 2 jet, or p{sub T} sum of the two other jets for [gamma] + 3 jet events. The results are compared to different models of multiple parton interactions (MPI) in the pythia and sherpa Monte Carlo (MC) generators. The data indicate a contribution from events with double parton (DP) interactions and are well described by predictions provided by the pythia MPI models with p{sub T}-ordered showers and by sherpa with the default MPI model. The [gamma] + 2 jet data are also used to determine the fraction of events with DP interactions as a function of the azimuthal angle and as a function of the second jet p{sub T}.

Download or read book Diphoton Production in P[bar P] Collisions At[radical] written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the inclusive[gamma][gamma] cross section (as a function of invariant mass and photon[epsilon][sub[tau]]), in p[bar p] collisions at[radical]s= 1.8 TeV, made using the D0 detector at the Fermilab Tevatron collider. The next is leading order (NLO) QCD prediction is found to be in good agreement with the data. The effects of invariant mass and diphoton balance cuts, which test the next-to-leading order contributions to the cross section, are investigated. We also compare the distribution of[kappa][sub[tau]] between samples of diphotons and highly electromagnetic jets, and find that the NLO QCD prediction models the shape of the[gamma][gamma][kappa][sub[tau]] distribution quite well.
