We study the applicability of the Z-Sum approach to multi-loop calculations with massive particles in perturbative quantum field theory. We systematically analyze the case of one-loop scalar integrals, which represent the building blocks...
ABSTRACT We calculate the associated production of a pseudoscalar (A) with a pair of heavy quarks at hadonic colliders, namely p pbar, pp →QQA + X for Q = b, t and X the remaining partonic interactions, including one-loop QCD corrections...
We present the calculation of heavy-quark associated production with a hard photon at hadron colliders, namely pp(p pbar) -> Q Qbar gamma +X (for Q = t, b), at Next-to-Leading Order (NLO) in Quantum Chromodynamics (QCD). We study the...
