Matching relations for gluon TMDs up to one-loop accuracy
Alessio Carmelo Alvaro, Nanako Kato, Barbara Pasquini +2
We present new results on the matching relations for gluon transverse momentum dependent parton distribution functions up to one-loop accuracy. At tree-level, employing the spinor…
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-…
Collinear matching for next-to-leading power transverse-momentum distributions
Simone Rodini, Alessio Carmelo Alvaro, Barbara Pasquini
Phenomenological studies of transverse momentum dependent (TMD) parton distributions rely on the expansion in small values of the transverse separation of fields, where TMD parton…
