Charm in Deep-Inelastic Scattering
Richard D. Ball, Marco Bonvini, Luca Rottoli
We show how to extend systematically the FONLL scheme for inclusion of heavy quark mass effects in DIS to account for the possible effects of an intrinsic charm component in the nu…
The prompt atmospheric neutrino flux in the light of LHCb
Rhorry Gauld, Juan Rojo, Luca Rottoli +2
The recent observation of very high energy cosmic neutrinos by IceCube heralds the beginning of neutrino astronomy. At these energies, the dominant background to the astrophysical…
Intrinsic charm in a matched general-mass scheme
Richard D. Ball, Valerio Bertone, Marco Bonvini +4
The FONLL general-mass variable-flavour number scheme provides a framework for the matching of a calculation in which a heavy quark is treated as a massless parton to one in which…
Towards parton distributions with fitted charm
Patrick Groth Merrild, Luca Rottoli
Modern parton distribution function fits require an accurate treatment of heavy quark mass effects. In this contribution, we discuss how the FONLL general-mass variable flavour num…
Parton distributions with threshold resummation
Marco Bonvini, Simone Marzani, Juan Rojo +6
We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNL…
Charm production in the forward region: constraints on the small-x gluon and backgrounds for neutrino astronomy
Rhorry Gauld, Juan Rojo, Luca Rottoli +1
The recent observation by the IceCube experiment of cosmic neutrinos at energies up to a few PeV heralds the beginning of neutrino astronomy. At such high energies, the conventiona…
