Simultaneous production of a boson and a charmed hadron at the LHC in general-mass variable-flavour-number scheme

Ville Alanko, Ilkka Helenius, Hannu Paukkunen

The simultaneous production of a boson and a charmed hadron in proton-proton collisions offers a potential probe for constraining the strange quark parton distribution func…

VALO1.0: New real-photon parton distributions with Monte Carlo uncertainties

Madhav Chithirasreemadam, Vadim Guzey, Felix Hekhorn +2

Performing a global QCD analysis of data on the photon structure function in scattering, we determine new leading order (LO) and next-to-leading (NLO) parton…

Dimuon production in neutrino-nucleus collisions at next-to-next-to-leading order in perturbative QCD

Ilkka Helenius, Hannu Paukkunen, Sami Yrjänheikki

Charm production in charged-current neutrino-nucleus deep-inelastic scattering (DIS), measured through dimuon final states, remains an important constraint of strangeness in global…

Improving the description of dimuon production in neutrino-nucleus collisions using the SACOT- scheme

Hannu Paukkunen, Ilkka Helenius, Sami Yrjänheikki

Dimuon production in deeply inelastic scattering between neutrinos and nuclei plays an important role in constraining the strange-quark parton distribution functions (PDFs). Here,…

Dimuon production in DIS with charm-mass effects

Ilkka Helenius, Hannu Paukkunen, Sami Yrjänheikki

Dimuon production in neutrino-nucleus collisions, an important constraint of strangeness in global parton distribution function analyses, is typically calculated by assuming it to…
