Efficient computation of Fourier-Bessel transforms for transverse-momentum dependent parton distributions and other functions
Markus Diehl, Oskar Grocholski
We present a method for the numerical computation of Fourier-Bessel transforms on a finite or infinite interval. The function to be transformed needs to be evaluated on a grid of p…
Phenomenology of diphoton photoproduction at next-to-leading order
Oskar Grocholski, Bernard Pire, Paweł Sznajder +2
We develop the analysis of diphoton exclusive photoproduction in the kinematics where a collinear QCD factorization framework applies, namely nearly forward large invariant mass di…
Artificial neural network modelling of generalised parton distributions
H. Dutrieux, O. Grocholski, H. Moutarde +1
We discuss the use of machine learning techniques in effectively nonparametric modelling of generalised parton distributions (GPDs) in view of their future extraction from experime…
Collinear factorization of diphoton photoproduction at next to leading order
Oskar Grocholski, Bernard Pire, Paweł Sznajder +2
We calculate in the framework of collinear factorization the amplitude for the photoproduction of a near forward large mass diphoton at leading twist and next to leading order (NLO…
Factorization in hard exclusive processes. Computation of one-loop corrections to the diphoton photoproduction on proton
Oskar Grocholski
Generalized Parton Distributions (GPDs) carry information on the internal structure of hadrons such as the angular momentum of quarks and gluons, or their spacelike distribution. T…
NLO collinear factorization of large mass diphoton photoproduction amplitude
Oskar Grocholski, Bernard Pire, Paweł Sznajder +2
We calculate large mass diphoton exclusive photoproduction in the framework of collinear QCD factorization at next to leading order in αs and at leading twist. Collinear divergence…
What do DVCS data tell us about TCS observables?
O. ~Grocholski, H. ~Moutarde, B. Pire +2
Deeply virtual Compton scattering (DVCS) and timelike Compton scattering (TCS) leading twist amplitudes are intimately related thanks to their analytic properties as a function of…
Data-driven study of timelike Compton scattering
O. Grocholski, H. Moutarde, B. Pire +2
In the framework of collinear QCD factorization, the leading twist scattering amplitudes for deeply virtual Compton scattering (DVCS) and timelike Compton scattering (TCS) are inti…
