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…
Factorization of the Energy-Energy Correlation in the two-jet limit in the massive case
Ugo Giuseppe Aglietti, Giancarlo Ferrera, Lorenzo Rossi
We consider non-logarithmic heavy-quark mass effects in the factorization and resummation of the Energy-Energy-Correlation (EEC) function, in the two-jet limit. We define a new, "p…
A global analysis of Energy-Energy Correlation data: determination of and non-perturbative QCD parameters
Ugo Giuseppe Aglietti, Giancarlo Ferrera, Lorenzo Rossi
We present a comprehensive global analysis of Energy-Energy Correlation (EEC) data in electron-positron annihilation into hadrons, spanning a wide range of center-of-mass energies…
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…
A Neural-Network Extraction of Unpolarised Transverse-Momentum-Dependent Distributions
Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +4
We present the first extraction of transverse-momentum-dependent distributions of unpolarised quarks from experimental Drell-Yan data using neural networks to parametrise their non…
Numerical implementation of evolution equations for twist-3 collinear PDFs
Simone Rodini, Lorenzo Rossi, Alexey Vladimirov
Twist-3 collinear parton distribution functions (PDFs) are matrix elements of quark-gluon-quark or three-gluons light-cone operators. They depend on three momentum fraction variabl…
