Book Measurement of the Inclusive Jet Cross Section in Pp Collisions at Sqrt s

Download or read book Measurement of the Inclusive Jet Cross Section in Pp Collisions at Sqrt s written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 inverse picobarns. The measurement is made for jet transverse momenta in the range 18-1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.

Book Measurement of the Inclusive Jet Cross Section in Proton antiproton Collisions at the Center of mass Energy of 1 96 TeV

Download or read book Measurement of the Inclusive Jet Cross Section in Proton antiproton Collisions at the Center of mass Energy of 1 96 TeV written by and published by . This book was released on 2008 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studies the high-energy collisions of protons and antiprotons. The data used in the measurement were collected during 2004-2005 with the D0 detector at the Tevatron Collider of the Fermi National Accelerator Laboratory and correspond to 0.7 fb−1 of integrated luminosity. High energy hadron collisions usually produce collimated sprays of particles called jets. The energy of the jets is measured using a liquid Argon-Uranium calorimeter and the production angle is determined with the help of silicon microstrip and scintillating fiber trackers. The inclusive jet cross section in proton-antiproton collisions is measured as a function of jet transverse momentum p{sub T} in six bins of jet rapidity at the center-of-mass energy √s = 1.96 TeV. The measurement covers jet transerve momenta from 50 GeV up to 600 GeV and jet rapidities up to.

Book Measurement of the Inclusive 3 jet Production Differential Cross Section in Proton proton Collisions at 7 TeV and Determination of the Strong Coupling Constant in the TeV Range

Download or read book Measurement of the Inclusive 3 jet Production Differential Cross Section in Proton proton Collisions at 7 TeV and Determination of the Strong Coupling Constant in the TeV Range written by and published by . This book was released on 2015 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a measurement of the inclusive 3-jet production differential cross section at a proton-proton centre-of-mass energy of 7 TeV using data corresponding to an integrated luminosity of 5 fb$^{-1}$ collected with the CMS detector. The analysis is based on the three jets with the highest transverse momenta. The cross section is measured as a function of the invariant mass of the three jets in a range of 445-3270 GeV and in two bins of the maximum rapidity of the jets up to a value of 2. A comparison between the measurement and the prediction from perturbative QCD at next-to-leading order is performed. Within uncertainties, data and theory are in agreement. The sensitivity of the observable to parameters of the theory such as the parton distribution functions of the proton and the strong coupling constant $\alpha_S$ is studied. A fit to all data points with 3-jet masses larger than 664 GeV gives a value of the strong coupling constant of $\alpha_S(M_\mathrm{Z})$ = 0.1171 $\pm$ 0.0013 (exp) $^{+0.0073}_{-0.0047}$ (theo).

Download or read book Measurement of the Ratio of Inclusive Cross Sections p p Z b jet p p Z jet in the Dilepton Final States written by and published by . This book was released on 2010 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inclusive production of b-jets with a Z boson is an important background to searches for the Higgs boson in associated ZH → llb{bar b} production at the Fermilab Tevatron collider. This thesis describes the most precise measurement to date of the ratio of inclusive cross sections [sigma](p{bar p} → Z + b-jet)/[sigma](p{bar p} → Z + jet) when a Z boson decays into two electrons or muons. The measurement uses a data sample from p{bar p} collisions at the center of mass energy √s = 1.96 TeV corresponding to an integrated luminosity of 4.2 fb−1 collected by the D0 detector. The measured ratio [sigma](Z + b-jet)/[sigma](Z + jet) is 0.0187 ± 0.0021(stat) ± 0.0015(syst) for jets with transverse momentum p{sub T} > 20 GeV and pseudorapidity.

Book Measurement of Mid rapidity Inclusive Jet Cross Section in Pp Collisions at    s

Download or read book Measurement of Mid rapidity Inclusive Jet Cross Section in Pp Collisions at s written by Dmitrii Kalinkin and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cross section for inclusive jet production in high-energy pp collisions is well described by pQCD in the collinear factorization framework, which, together with its high rate and clear signal, makes it a key observable to study the proton structure. For pp collisions at RHIC at a center-of-mass energy of √s = 200 GeV, the STAR detector provides jet measurements at 0.07 ≲ xT ≡ 2pT:jet/√s ≲ 0.5. At these kinematics, the direct scattering on gluons inside the colliding protons contributes at least half of the total jet production cross section. Measurements of the inclusive jet cross section at RHIC, together with the past Deep Inelastic Scattering measurements, can provide improved constraints on the gluon Parton Distribution Function at high x.

Book Measurement of the T T bar Production Cross Section in Pp Collisions at 7 TeV in Lepton   Jets Events Using B quark Jet Identification

Download or read book Measurement of the T T bar Production Cross Section in Pp Collisions at 7 TeV in Lepton Jets Events Using B quark Jet Identification written by and published by . This book was released on 2011 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new measurement of the inclusive production cross section for pp to t t-bar is performed at a center-of-mass energy of 7 TeV using data collected by the CMS experiment at the LHC. The analysis uses a data sample corresponding to an integrated luminosity of 36 inverse picobarns, and is based on the final state with one isolated, high transverse momentum muon or electron, missing transverse energy, and hadronic jets. The ttbar content of the selected events is enhanced by requiring the presence of at least one jet consistent with b-quark hadronization. The measured cross section is 150 +/- 9 (stat.) +/- 17 syst.) +/- 6 (lumi.) pb and is in agreement with higher-order QCD calculations. The combination of this measurement with a previous CMS result based on dileptons gives 154 +/- 17 (stat.+syst.) +/- 6 (lumi.) pb.
