Symbolic Extraction of Non-Perturbative Transverse-Momentum-Dependent Distributions from Drell-Yan Data
Cole Granger, Alessandro Bacchetta, Valerio Bertone +6
We present an analytical parametrization of the non-perturbative transverse-momentum-dependent (TMD) parton distribution function of unpolarized quarks, extracted from Drell-Yan da…
A first extraction of gluon TMDs from Higgs data at the LHC
Simone Anedda, Valerio Bertone, Giuseppe Bozzi +1
We present the first extraction of the unpolarised gluon transverse-momentum-dependent (TMD) parton distribution from Higgs-boson production data at the LHC within the framework of…
An extraction of the Collins-Soper kernel from a joint analysis of experimental and lattice data
Artur Avkhadiev, Valerio Bertone, Chiara Bissolotti +6
We present a first joint extraction of the Collins-Soper kernel (CSK) combining experimental and lattice QCD data in the context of an analysis of transverse-momentum-dependent dis…
Extraction of Dihadron Fragmentation Functions at NNLO with and without Neural Networks
Virgile Mahaut, Luca Polano, Alessandro Bacchetta +4
We present a new extraction of unpolarized Dihadron Fragmentation Functions, which describe the probability density for an unpolarized parton to fragment into a pair. O…
Perturbative RGE systematics in precision observables
Valerio Bertone, Giuseppe Bozzi, Francesco Hautmann
QCD calculations for collider physics make use of perturbative solutions of renormalisation group equations (RGEs). Ambiguities related to these solutions can contribute significan…
One-loop matching for leading-twist generalised transverse-momentum-dependent distributions
Valerio Bertone, Miguel G. Echevarria, Ãscar del Rio +1
We present the one-loop matching coefficients necessary to match all of the leading-twist generalised transverse-momentum-dependent distributions (GTMDs) onto generalised parton di…
