RPA treatment of a motivated QCD Hamiltonian in the SO(4) (2 + 1) -flavor limit: Light and strange mesons
(World Scientific, 2017-04)
The SO(4) symmetry of a sector of the quantum chromodynamics (QCD) Hamiltonian was analyzed in a previous work. The numerical calculations were then restricted to a particle-hole (ph) space and the comparison with experimental ...
Diphoton production at the LHC: a QCD study up to NNLO
(Springer, 2018-04)
We consider the production of prompt-photon pairs at the LHC and we report on a study of QCD radiative corrections up to the next-to-next-to-leading order (NNLO). We present a detailed comparison of next-to-leading order ...
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 ...
Production of Drell-Yan lepton pairs in hadron collisions: Transverse-momentum resummation at next-to-next-to-leading logarithmic accuracy
(Elsevier Science, 2011-01)
We consider the transverse-momentum (qT) distribution of Drell-Yan lepton pairs produced in hadron collisions. At small values of qT, we resum the logarithmically-enhanced perturbative QCD contributions up to next-to-nex ...
Deconfinement and chiral restoration within the SU(3) Polyakov-Nambu-Jona- Lasinio and entangled Polyakov-Nambu-Jona-Lasinio models in an external magnetic field
(American Physical Society, 2014-01)
The behavior of the quark condensates at zero chemical potential and finite temperature subject to an external magnetic field is studied within the three flavor Nambu-Jona-Lasinio model with Polyakov loop (PNJL) and its ...
Precision studies of observables in pp → W → lνl and pp → γ , Z → l +l − processes at the LHC
(Springer, 2017-05)
This report was prepared in the context of the LPCC "Electroweak Precision Measurements at the LHC WG" and summarizes the activity of a subgroup dedicated to the systematic comparison of public Monte Carlo codes, which ...
Generalized Ginzburg-Landau approach to inhomogeneous phases in nonlocal chiral quark models
(Elsevier Science, 2015-05)
We analyze the presence of inhomogeneous phases in the QCD phase diagram within the framework of nonlocal chiral quark models. We concentrate in particular in the positions of the tricritical (TCP) and Lifshitz (LP) points, ...
Triple collinear splitting functions at NLO for scattering processes with photons
(Springer, 2014-10)
Abstract: We present splitting functions in the triple collinear limit at next-to-leading order. The computation was performed in the context of massless QCD+QED, considering only processes which include at least one photon. ...
The back-to-back region in e+e- energy-energy correlation
(Elsevier Science, 2005-01)
We consider the back-to-back region in the energy-energy correlation in e+e- collisions. We present the explicit expression of the O (αS2) logarithmically enhanced contributions up to next-to-next-to-leading logarithmic ...
