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…
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-…
Determination of quark-gluon-quark interference within the proton
Alexey Vladimirov, Guillermo Portela, Simone Rodini
Quarks and gluon, as quantum particles, are subjects to various effects that go beyond the naive parton picture and are not captured by ordinary parton densities. In this work, we…
Transverse momentum dependent factorization for SIDIS at next-to-leading power
Simone Rodini, Alexey Vladimirov
The semi-inclusive deep-inelastic scattering (SIDIS) is the golden process for investigating the nucleon's transverse momentum-dependent (TMD) structure. We present the complete ex…
Sivers, Boer-Mulders and worm-gear distributions at next-to-leading order
Felix Rein, Simone Rodini, Andreas Schäfer +1
We compute the Sivers, Boer-Mulders, worm-gear (T and L) transverse momentum dependent distributions in terms of twist-two and twist-three collinear distributions in the small-b li…
