Higher-order structure of Hamiltonian truncation effective theory
Andrea Maestri, Simone Rodini, Barbara Pasquini
We study the Hamiltonian truncation for the two-dimensional theory within the framework of Hamiltonian truncation effective theory, where truncation artifacts are mitigate…
Collinear matching for leading power gluon transverse momentum distributions
Alessio Carmelo Alvaro, Nanako Kato, Barbara Pasquini +2
We compute the tree-level and one-loop matching relations for leading power gluon transverse momentum dependent parton distribution functions. At tree-level, working within the spi…
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-…
