Drell-Yan processes in the high-energy limit
Simone Marzani, Richard D. Ball
We present the analytic computation of leading high-energy logarithms of the inclusive Drell-Yan and vector boson production cross-section. We also study the phenomenological relev…
Precision determination of electroweak parameters and the strange content of the proton from neutrino deep-inelastic scattering
The NNPDF Collaboration, Richard D. Ball, Luigi Del Debbio +6
We use recent neutrino dimuon production data combined with a global deep-inelastic parton fit to construct a new parton set, NNPDF1.2, which includes a determination of the strang…
Hybrid Quintessential Inflation
Mar Bastero-Gil, Arjun Berera, Brendan M. Jackson +1
A model is presented in which a single scalar field is responsible for both primordial inflation at early times and then dark energy at late times. This field is coupled to a secon…
Factorization constraints for soft anomalous dimensions in QCD scattering amplitudes
Einan Gardi, Lorenzo Magnea
We study the factorization of soft and collinear singularities in dimensionally-regularized fixed-angle scattering amplitudes in massless gauge theories. Our factorization is based…
Electroproduction of the N*(1535) resonance at large momentum transfer
V. M. Braun, M. Göckeler, R. Horsley +11
We report on the first lattice calculation of light-cone distribution amplitudes of the N*(1535) resonance, which are used to calculate the transition form factors at large momentu…
High Energy Resummation of Drell-Yan Processes
Simone Marzani, Richard D. Ball
We present a computation of the inclusive Drell-Yan production cross-section in perturbative QCD to all orders in the limit of high partonic centre-of-mass energy. We compare our r…
