Transverse-momentum resummation for the signal-background interference in the H →γγ channel at the LHC
(American Physical Society, 2017-09)
We present an upgraded calculation of the effects of resonance-continuum interference for the Higgs boson decaying to two photons at the Large Hadron Collider, at next-to-leading order in the strong coupling αS, O(αS3), ...
Universality of transverse-momentum resummation and hard factors at the NNLO
(Elsevier Science, 2014-04)
We consider QCD radiative corrections to the production of colorless high-mass systems in hadron collisions. The logarithmically-enhanced contributions at small transverse momentum are treated to all perturbative orders ...
Transverse-momentum resummation: Higgs boson production at the Tevatron and the LHC
We consider the transverse-momentum (qT ) distribution of Standard Model Higgs bosons produced by gluon fusion in hadron collisions. At small qT (qT < mH, mH being the mass of the Higgs boson), we resum the logarithmical ...
Single-inclusive jet production in polarized pp collisions at RHIC to next-to-leading logarithmic accuracy
We perform the resummation of large logarithmic corrections to the partonic cross sections for single-inclusive jet production in polarized pp collisions. We reach the next-to-leading logarithmic accuracy for this observable ...
Resummation of infrared divergences in the free energy of spin-two fields
(AMER PHYSICAL SOC, 2009)
We derive a closed form expression for the sum of all the infrared divergent contributions to the free energy of a gas of gravitons. An important ingredient of our calculation is the use of a gauge fixing procedure such ...
Scalar coupling evolution in a non-perturbative QCD resummation scheme
We compute the Standard Model scalar coupling (λ) evolution in a particular QCD resummation scheme, where the QCD coupling becomes infrared finite due to the presence of a dynamically generated gluon mass, leading to the ...
Threshold resummation at N3LL accuracy and soft-virtual cross sections at N3LO
(Elsevier Science, 2014-11)
We consider QCD radiative corrections to the production of colorless high-mass systems in hadron collisions. We show that the recent computation of the soft-virtual corrections to Higgs boson production at N3LO together ...
Higgs boson production at the LHC: Transverse-momentum resummation and rapidity dependence
(Elsevier Science, 2008-03)
We consider Higgs boson production by gluon fusion in hadron collisions. We study the doubly-differential transverse-momentum (qT) and rapidity (y) distribution of the Higgs boson in perturbative QCD. In the region of small ...
Higgs pair production at next-to-next-to-leading logarithmic accuracy at the LHC
We perform the threshold resummation for Higgs pair production in the dominant gluon fusion channel to next-to-next-to-leading logarithmic (NNLL) accuracy. The calculation includes the matching to the next-to-next-to-leading ...
