Heavy-quark pair production at two loops in QCD
نویسندگان
چکیده
We present updated predictions for the total cross section of top-quark pair production at Tevatron and LHC. For the LHC we also provide results at √ s = 10 TeV, in view of the anticipated run in 2008 and quote numbers for the production of new heavy-quark pairs with mass in the range 0.5 – 2 TeV. Our two-loop results incorporate all logarithmically enhanced terms near threshold including Coulomb corrections as well as the exact dependence on the renormalization and factorization scale through next-to-next-to-leading order in QCD.

Production of two Z-bosons in gluon fusion in the heavy top quark approximation
We compute QCD radiative corrections to the continuum production of a pair of Z-bosons in the annihilation of two gluons. We only consider the contribution of the top quark loops and we treat them assuming that mt is much larger than any other kinematic invariant in the problem. We estimate the QCD corrections to pp → ZZ using the first non-trivial term in the expansion in the inverse top quark...
متن کاملTops from Light Quarks: Full Mass Dependence at Two-Loops in QCD
I present the two-loop QCD corrections to the production of a massive quarkanti-quark pair in the massless quark-anti-quark annihilation channel. The result is obtained as a combination of a deep expansion in the mass around the high energy limit and of a numerical integration of a system of differential equations. The primary application of the outcome and developed methods is top quark pair p...
متن کاملTwo-loop fermionic corrections to heavy-quark pair production: the quark-antiquark channel
We evaluate the fermionic two-loop QCD corrections to the heavy-quark pair production process in the quark-antiquark channel. We obtain analytic results which are valid for any value of the Mandelstam invariants s and t, and of the heavy quark mass m. Our findings confirm previous results for the analytic evaluation in the small-mass limit and numerical results for the exact amplitude. We furth...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملHeavy quark production at HERA and the LHC
Measurements of heavy quark production, particularly from HERA, their theoretical understanding and their relevance for the LHC are reviewed1. The status of beauty and charm production is discussed in the context of the different components of the production process: the parton density function of the colliding hadrons; the hard scatter; and the fragmentation of the quarks into hadrons. The the...
