Kinematic distributions of the η c leptoproduction in association with light hadrons
Journal of High Energy Physics, 2021 The η c meson leptoproduction is calculated within the nonrelativistic QCD framework for the first time. It is found that the colour-singlet channel, although suppressed by a factor of α s relative to the colour-octet ones, provides important ...

Wigner distributions and quark orbital angular momentum
, 2012 We discuss the quark phase-space or Wigner distributions of the nucleon which combine in a single picture all the information contained in the generalized parton distributions and the transverse-momentum dependent parton distributions.

Light distribution modulated diffuse reflectance spectroscopy
Biomedical Optics Express, 2016 Typically, a diffuse reflectance spectroscopy (DRS) system employing a continuous wave light source would need to acquire diffuse reflectances measured at multiple source-detector separations for determining the absorption and reduced scattering coefficients of turbid samples.

Heavy-quark mass effects in off-light-cone distributions
European Physical Journal C: Particles and FieldsWe compute the one-loop correction to the forward matrix element of an off-light-cone bi-local quark correlator characterised by a space-like separation $$z^2$$ z 2 in the presence of heavy quarks with mass m.

The gluon structure of hadrons and nuclei from lattice QCD
EPJ Web of Conferences, 2018 I discuss recent lattice QCD studies of the gluon structure of hadrons and light nuclei. After very briefly highlighting new determinations of the gluon contributions to the nucleon’s momentum and spin, presented by several collaborations over the last ...

Factorization Theorem Relating Euclidean and Light-Cone Parton Distributions
, 2018 In a large-momentum nucleon state, the matrix element of a gauge-invariant Euclidean Wilson line operator accessible from lattice QCD can be related to the standard light-cone parton distribution function through the large-momentum effective theory ...

Light-front quark model consistent with Drell-Yan-West duality and quark counting rules
, 2013 We propose a phenomenological light-front wave function for hadrons with arbitrary twist-dimension (mesons, baryons and multiquark states), which gives the correct scaling behavior of structure functions (parton distributions) and form factors for pions ...

Quark distrbutions in the nucleon based on a relativistic 3-body approach to the NJL model [PDF]
, 1999 Quark light cone momentum distributions in the nucleon are calculated in a relativistic 3-body approach to the NJL model by using a simple 'static approximation' for the Faddeev kernel.

Light Meson Distribution Amplitudes
, 2010 We calculated the first two moments of the light-cone distribution amplitudes for the pseudoscalar mesons ($ $ and $K$) and the longitudinally polarised vector mesons ($ $, $K^*$ and $ $) as part of the UKQCD and RBC collaborations' $N_f=2+1$ domain-wall fermion phenomenology programme.
