Linearly-polarized small-x gluons in forward heavy-quark pair production
Cyrille Marquet, Claude Roiesnel, Pieter Taels
We use the Color Glass Condensate (CGC) framework to study the production of forward heavy quark-antiquark pairs in unpolarized proton-nucleus or proton-proton collisions in the sm…
Transverse-momentum-dependent gluon distributions from JIMWLK evolution
C. Marquet, E. Petreska, C. Roiesnel
Transverse-momentum-dependent (TMD) gluon distributions have different operator definitions, depending on the process under consideration. We study that aspect of TMD factorization…
The Infrared Behaviour of the Pure Yang-Mills Green Functions
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We review the infrared properties of the pure Yang-Mills correlators and discuss recent results concerning the two classes of low-momentum solutions for them reported in literature…
Virtual Compton Scattering off a Spinless Target in the AdS/QCD correspondence
C. Marquet, C. Roiesnel, S. Wallon
We perform a study of the doubly virtual Compton scattering off a spinless target gamma* P -> gamma* P' within the Anti-de Sitter(AdS)/QCD formalism. We find that the general struc…
Virtual Compton Scattering off a Spinless Target in AdS/QCD
Cyrille Marquet, Claude Roiesnel, Samuel Wallon
We study the doubly virtual Compton scattering off a spinless target within the Anti-de Sitter(AdS)/QCD formalism. We find that the general structure allowed by the…
On AdS/QCD correspondence and the partonic picture of deep inelastic scattering
B. Pire, C. Roiesnel, L. Szymanowski +1
We critically examine the question of scaling of the Deep Inelastic Scattering process in the medium Bjorken x region on a scalar boson in the framework of the AdS/QCD corresponden…
Divergent IR gluon propagator from Ward-Slavnov-Taylor identities?
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +5
We exploit the Ward-Slavnov-Taylor identity relating the 3-gluons to the ghost-gluon vertices to conclude either that the ghost dressing function is finite and non vanishing at zer…
Constraints on the IR behaviour of gluon and ghost propagator from Ward-Slavnov-Taylor identities
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +5
We consider the constraints of the Slavnov-Taylor identity of the IR behaviour of gluon and ghost propagators and their compatibility with solutions of the ghost Dyson-Schwinger eq…
Power Corrections to Perturbative QCD and OPE in Gluon Green Functions
D. Becirevic, Ph. Boucaud, F. De Soto +6
We show that QCD Green functions in Landau Gauge exhibit sizable corrections to the expected perturbative behavior at energies as high as 10 GeV. We argue that these are…
Unquenched calculation of alpha_s from Green functions: progress report
Ph. Boucaud, J. P. Leroy, J. Micheli +4
We present preliminary results on the computation of the QCD running coupling constant in the MOM_tilde scheme and Landau gauge with two flavours of dynamical Wilson quarks. Gluon…
Preliminary Calculation of from Green Functions with Dynamical Quarks
Ph. Boucaud, J. P. Leroy, H. Moutarde +4
We present preliminary results on the computation of the QCD running coupling constant in the scheme and Landau gauge with two flavours of dynamical Wilson quarks…
Lattice calculation of corrections to and of in the scheme
Ph. Boucaud, G. Burgio, F. Di Renzo +8
We report on very strong evidence of the occurrence of power terms in $\as(p)$, the QCD running coupling constant in the scheme, by analyzing non-perturbative mea…
Asymptotic scaling of the gluon propagtor on the lattice
D. Becirevic, Ph. Boucaud, J. P. Leroy +4
We pursue the study of the high energy behaviour of the gluon propagator on the lattice in the Landau gauge in the flavorless case (n_f=0). It was shown in a precedin g paper that…
Asymptotic behaviour of the gluon propagator from lattice QCD
D. Becirevic, Ph. Boucaud, J. P. Leroy +4
We study the flavorless gluon propagator in the Landau gauge from high statistics lattice calculations. Hypercubic artifacts are efficiently eliminated by taking the $\sum p_μ^4 \t…
Lattice calculation of in momentum scheme
Ph. Boucaud, J. P. Leroy, J. Micheli +2
We compute the flavorless running coupling constant of QCD from the three gluon vertex in the (regularisation independent) momentum subtraction renormalisation scheme. This is perf…
Three-loop beta function and non-perturbative in asymmetric momentum scheme
Ph. Boucaud, J. P. Leroy, J. Micheli +2
We determine the three-loop coefficient of the beta function in the asymmetric momentum subtraction scheme in Landau gauge. This scheme is convenient for lattice studies of α_s, th…
Study of the Strongly Interacting Higgs Physics Model with Heavy Fermions
L. V. Dung, G. Jikia, C. Roiesnel +1
We study the effect of a possible fourth heavy generation of fermions on the Higgs sector of the standard model. We show, from the violation of elastic unitarity, that the scale of…
