Parton Distribution Functions and their Generalizations
Cédric Lorcé, A. Metz, B. Pasquini +1
This article is an introduction to parton distribution functions and their generalizations which describe the quark and gluon structure of hadrons, and can be measured in various h…
Perturbative results for the matrix elements of the vector current and the role of different infrared regulators
Alessio Carmelo Alvaro, Ignacio Castelli, Cédric Lorcé +3
We investigate the twist-2 unpolarized generalized parton distributions (GPDs) of quarks for an on-shell gluon target in quantum chromodynamics. These GPDs parametrize the leading-…
Mapping the transverse spin sum rule in position space
Cédric Lorcé, Asmita Mukherjee, Ravi Singh +1
We discuss in detail the relativistic spatial distribution of transverse angular momentum, including both orbital and intrinsic spin contributions. Using the quantum phase-space fo…
Pressure inside hadrons: criticism, conjectures, and all that
Cédric Lorcé, Peter Schweitzer
The interpretation of the energy-momentum tensor form factor of hadrons in terms of pressure and shear force distributions is discussed, concerns raised in the literature ar…
