Abstract

In this contribution, some of the recent QCD results on jet production from the CDF and D0 experiments in Run II of the Tevatron are discussed. In particular, results include cross section measurements for dijet and trijet production, study of jet substructure and measurements of W/Z+jets cross sections. The measurements are compared with the theoretical predictions. The QCD program at the Tevatron proton-antiproton collider revolves around the jet physics. Jets are collimated sprays of hadrons generated by the fragmentation of partons originating from the hard scattering. The measurements of jets production cross section at the Tevatron provide stringent test of perturbative QCD predictions, information on the strong coupling constant, {alpha}s, and constraints on proton parton distribution functions, PDFs. The deviations from the pQCD predictions could translate into a hint of new physics. In addition, these processes form sizable backgrounds to both, the Standard Model (SM) and beyond SM physics processes. Therefore, good understanding of jets production is essential to perform precise physics measurements or searches for new physics phenomena. In this contribution, a review of some recent QCD results from the CDF [1] and D0 [2] experiments is presented. Various analyses use proton-antiproton collision data from the Fermilab Tevatron atmore »« less

Measurement of the inclusive isolated prompt photon production cross section at the Tevatron using the CDF detector

Thesis/Dissertation Deluca Silberberg, Carolina

In this thesis we present the measurement of the inclusive isolated prompt photon cross section with a total integrated luminosity of 2.5 fb^-1 of data collected with the CDF Run II detector at the Fermilab Tevatron Collider. The prompt photon cross section is a classic measurement to test perturbative QCD (pQCD) with potential to provide information on the parton distribution function (PDF), and sensitive to the presence of new physics at large photon transverse momentum. Prompt photons also constitute an irreducible background for important searches such as H → γγ, or SUSY and extra-dimensions with energetic photons in the finalmore »« less

Measurement of $$Z/\gamma^* + b$$-jet Production Cross section in $$p\bar{p}$$ collisions at $$\sqrt{s}= 1.96$$ TeV with the CDF detector

Thesis/Dissertation Ortolan, Lorenzo

Processes at hadron colliders, such as the production of jets, are described by the Quantum Chromodynamics theory (QCD). Precise descriptions of processes involving jets in association with a vector boson have nowadays large relevance as they represent irreducible background to other Standard Model (SM) processes and searches for new physics. The experimental study and understanding of the b-jet production in association with a Z boson are crucial for many reasons. For one side, it is the most important background for a light Higgs boson decaying into a bottom-antibottom quark pair and produced in the ZH mode.This is one of themore »« less

QCD at DOe: A Review of Recent Results

Journal Article Sawyer, Lee - AIP Conference Proceedings

We report a variety of measurements of hadronic final states, ranging from elastic scattering of protons to events with highly energetic jets, based on data taken with the DOe experiment at the Fermilab Tevatron proton-antiproton collider.Starting with the non-perturbative regime, we report measurement of the pp-bar elastic differential scattering cross section, using DOe's Forward Proton Detectors (FPD). We present a new way to describe minimum bias events based on angular distributions in {approx_equal}5 million minimum bias pp-bar collisions collected between April 2002 and February 2006 with the DOe detector. We demonstrate that the distribution of {Delta}{phi} in the detector transversemore »« less

Measurement of the inclusive jet cross section in proton-antiproton collisions at the center-of-mass energy of 1.96 TeV

Thesis/Dissertation Voutilainen, Mikko

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_Tmore »« less

Measurement of the electroweak top quark production cross section and the CKM matrix element Vtb with the D0 experiment

Thesis/Dissertation Kirsch, Matthias

At particle accelerators the Standard Model has been tested and will be tested further to a great precision. The data analyzed in this thesis have been collected at the world's highest energetic-collider, the Tevatron, located at the Fermi National Accelerator Laboratory (FNAL) in the vicinity of Chicago, IL, USA. There, protons and antiprotons are collided at a center-of-mass energy of {radical}s = 1.96 TeV. The discovery of the top quark was one of the remarkable results not only for the CDF and D0 experiments at the Tevatron collider, but also for the Standard Model, which had predicted the existence ofmore »« less
