The Top Cross Section in Hadronic Collisions
We reexamine the top quark production cross section at the Tevatron and LHC, in the light of recent progress on the resummation of logarithmic soft gluon corrections. We find that resummation effects are much smaller than previously thought. We also compute Coulombic threshold effects, and find them negligible. We update the discussion of uncertainties due to scale dependence, the value of the ...
متن کاملHATHOR - HAdronic Top and Heavy quarks crOss section calculatoR
Required libraries: The code uses the FF library [3] to calculate scalar one-loop integrals and the dilogarithm. Random numbers for the Monte Carlo integration are generated using the Ranlux library written by Martin Lüscher [4]. Monte Carlo integration is done using an adapted version of Vegas [5, 6]. For convenience Ranlux and the FF library are included in the package. Please cite the aforem...
متن کاملTop Quark Distributions in Hadronic Collisions
We present kinematical distributions for top quark pairs produced at the Tevatron pp̄ Collider, as predicted within Next-to-Leading-Order QCD. We consider single and double-inclusive distributions, and compare our results to those obtained with the shower Monte Carlo HERWIG. We discuss the implications of our findings for experimental issues such as the measurement of the top quark mass. CERN-TH...
متن کاملThreshold Resummation of the Total Cross Section for Heavy Quark Production in Hadronic Collisions
We discuss calculations of the inclusive total cross section for heavy quark production at hadron collider energies within the context of perturbative quantum chromodynamics, including resummation of the effects of initial-state soft gluon radiation to all orders in the strong coupling strength. We resum the universal leading-logarithm contributions, and we restrict our integrations to the regi...
متن کاملTop Pair Production Cross-section Measurement in the All-hadronic Channel at Cdf and Dø
Measurements of the tt̄ production cross-section at √ s = 1.96 TeV in proton-antiproton collisions were performed by the CDF and DØ collaborations using tt̄ final states where both W ’s decay hadronically. Each experiment uses luminosity of about 160 pb of data collected during Run II of the Fermilab Tevatron collider. Beside kinematical observables both experiments take advantage of identifying ...
