Probing Spin Dependent Quark and Gluon Distributions Through Azimuthal and Polarization Asymmetries

EPJ Web of Conferences, 2016
Spin and transverse momentum dependent parton distributions - Generalized Parton Distributions, Transverse Momentum Distributions and related distributions - are at the interface between the QCD structure of the hadrons and observable quantities.

Top-quark pole mass extraction at NNLO accuracy, from total, single- and double-differential cross sections for t t ¯ $$ t\overline{t} $$ + X production at the LHC

Journal of High Energy Physics
We extract the top-quark mass value in the on-shell renormalization scheme from the comparison of theoretical predictions for pp → t t ¯ $$ t\overline{t} $$ + X at next-to-next-to-leading order (NNLO) QCD accuracy with experimental data collected by the ...

Evolution of colour correlated double parton distributions: a quantitative study

Journal of High Energy Physics
Double parton distributions satisfy the same evolution equations as ordinary single-parton densities, provided that the colours of the two partons are uncorrelated.

Longitudinal and transverse parton momentum distributions for pion and nucleon within relativistic constituent quark models

EPJ Web of Conferences, 2010
Longitudinal and transverse quark momentum distributions for the pion and the nucleon are calculated from quark-hadron vertexes obtained by an investigat ion of electromagnetic form factors within relativistic constituent quark models. The no-helicity

Exploring twist-4 chiral-even GPDs in the light-front quark-diquark model

Nuclear Physics B
In this work, we delve into the realm of quantum chromodynamics (QCD) by calculating twist-4 chiral-even generalized parton distributions (GPDs), within the context of the light-front quark-diquark model (LFQDM), focusing specifically on the intriguing ...
