Measurement of the Inclusive Isolated Photon Cross Section at CDF
We present preliminary results on inclusive direct photon production in pp̄ collisions at √ s=1.96 TeV, using data collected with the upgraded Collider Detector at Fermilab in Run II, corresponding to an integrated luminosity of 451 pb. Measurements are performed as a function of the photon transverse momentum for photons with pT >30 GeV and |η| <1.0. Photons are required to be isolated in the c...
متن کاملInclusive Jet Cross Section at CDF
This contribution reports on preliminary measurements of the inclusive jet production cross section in p ¯ p collisions at √ s = 1.96 TeV using data collected with CDF corresponding to an integrated luminosity of 385 pb −1. Two analyzes are presented: one uses the longitudinally invariant k T algorithm to reconstruct the jets, the other uses the midpoint algorithm. Both are limited to jets with...
متن کاملInclusive Jet Cross-section Measurements at Cdf
The measurement of the inclusive jet cross section at the Tevatron is an important test of perturbative QCD (pQCD) predictions over more than 8 orders of magnitude, probing distances down to 10m. The increased center-of-mass energy in Run II (from 1.8 TeV to 1.96 TeV), the highly upgraded CDF detector1, and the amount of data collected allow jet measurements in an extended region of jet transve...
متن کاملTop Cross Section and Standard Model Properties at CDF
We present recent results on top quark pair production cross section in several final states as well as a spin correlations measurement and two W-helicity measurements from the CDF detector at the Tevatron pp̄ collider operating at √ s = 1.96 TeV. The most precise single tt̄ cross section measurement, in the lepton+jets final state, using a Neural Network kinematic fit, yields a value of 6.8 ± 0....
متن کاملTotal Hadronic Cross-Section of Photon-Photon Interactions at LEP
The total hadronic cross-section σγγ(W ) for the interaction of real photons, γγ → hadrons, is measured for γγ centre-of-mass energies 10 ≤ W ≤ 110 GeV. The cross-section is extracted from a measurement of the process ee → eeγγ → ee + hadrons, using a luminosity function for the photon flux together with form factors for extrapolating to real photons (Q = 0 GeV). The data were taken with the OP...
