    • A Master formula for NNLO soft and virtual QCD corrections. 

      Kidonakis, Nikolaos (HEP, Cavendish Laboratory, University of Cambridge, 2003-06)
      I present a master formula for the next-to-next-to-leading order (NNLO) soft and virtual QCD corrections for any process in hadron-hadron and lepton-hadron colliders. The formula is derived from a unified threshold resummation ...
    • Next-to-next-to-leading order soft and virtual corrections for QCD, Higgs and SUSY processes. 

      Kidonakis, Nikolaos (HEP, Cavendish Laboratory, University of Cambridge, 2004-01)
      I review recent advances in the calculation of higher-order soft-gluon corrections for a variety of QCD, Higgs, and SUSY processes in hadron colliders. A unified approach and master formulas for next-to-next-to-leading ...
    • Next-to-next-to-leading order soft gluon corrections in direct photon production. 

      Kidonakis, Nikolaos; Owens, J. F. (HEP, Cavendish Laboratory, University of Cambridge, 2003-07)
      Previous work on soft-gluon resummation for direct photon production is extended to include additional subleading logarithmic terms through O( 3s ) and some representative comparisons are made to experimental results ...
    • Next-to-next-to-leading order soft gluon corrections in top quark hadroproduction. 

      Kidonakis, Nikolaos; Vogt, Ramona (HEP, Cavendish Laboratory, University of Cambridge, 2003-08)
      We calculate next-to-next-to-leading order soft-gluon corrections to top quark total and differential cross sections in hadron colliders. We increase the accuracy of our previous estimates by including additional subleading ...
    • NNLO soft and virtual corrections for electroweak, Higgs, and SUSY processes. 

      Kidonakis, Nikolaos (HEP, Cavendish Laboratory, University of Cambridge, 2003-07)
      I present applications of a master formula for next-to-next-to-leading order soft and virtual QCD corrections to various electroweak, Higgs, and supersymmetric processes. They include Drell-Yan and charged Higgs production, ...
    • Resummation of transverse momentum and mass logarithms in DIS heavy quark production. 

      Nadolsky, Pavel M.; Kidonakis, Nikolaos; Olness, Frederick I.; Yuan, C. P. (HEP, Cavendish Laboratory, University of Cambridge, 2002-10)
    • Threshold corrections in bottom and charm quark hadroproduction at next-to-next-to-leading order. 

      Kidonakis, Nikolaos; Vogt, Ramona (HEP, Cavendish Laboratory, University of Cambridge, 2004-01)
      We calculate threshold soft-gluon corrections to total cross sections and transverse momentum distributions for bottom and charm quark production in fixed-target experiments, considering both pp and −p interactions. We ...
    • Threshold effects in charm hadroproduction. 

      Kidonakis, Nikolaos; Laenen, Eric; Moch, Sven; Vogt, Ramona (HEP, Cavendish Laboratory, University of Cambridge, 2002-12)
      We describe calculations of cc production to next-to-next-to-leading order (NNLO) and next-to-next-to-leading logarithm (NNLL) near threshold in pp and −p interactions. We study the relevance of these calculations for ...
    • Top quark production at the Tevatron at NNLO. 

      Kidonakis, Nikolaos; Vogt, Ramona (HEP, Cavendish Laboratory, University of Cambridge, 2003-09)
      We present results for top quark production at the Tevatron including next-to-nextto- leading order (NNLO) soft-gluon corrections. We show the stability of the cross section with respect to kinematics choice and scale ...
    • Two loop and N loop eikonal vertex corrections. 

      Kidonakis, Nikolaos (HEP, Cavendish Laboratory, University of Cambridge, 2003-07)
      I present calculations of two-loop vertex corrections with massive and massless partons in the eikonal approximation. I show that the n-loop result for the UV poles can be given in terms of the one-loop calculation.
    • A Unified approach to NNLO soft and virtual corrections in electroweak, Higgs, QCD, and SUSY processes. 

      Kidonakis, Nikolaos (HEP, Cavendish Laboratory, University of Cambridge, 2003-03)
      I present a unified approach to calculating the next-to-next-to-leading order (NNLO) soft and virtual QCD corrections to cross sections for electroweak, Higgs, QCD, and SUSY processes. I derive master formulas that can ...
    • W Boson production at large transverse momentum. 

      Kidonakis, Nikolaos; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 2004-05)
      The production of W bosons at large transverse momentum in p¯p collisions is studied. The next-to-leading order cross section in this region is dominated by threshold soft-gluon corrections. The transverse momentum ...
    • W hadroproduction at large transverse momentum beyond next-to-leading order. 

      Kidonakis, Nikolaos; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 2003-11)
      We study the production of W bosons at large transverse momentum in p¯p collisions. We show that the next-to-leading order cross section at large transverse momentum is dominated by threshold soft-gluon corrections. We ...
