Physical factorisation scheme for PDFs for non-inclusive applications
E. G. de Oliveira, A. D. Martin, M. G. Ryskin
We introduce the physical factorisation scheme, which is necessary to describe observables which are `not completely inclusive'. We derive the formulae for NLO DGLAP evolution in t…
Unintegrated parton distributions in nuclei
E. G. de Oliveira, A. D. Martin, F. S. Navarra +1
We study how unintegrated parton distributions in nuclei can be calculated from the corresponding integrated partons using the EPS09 parametrization. The role of nuclear effects is…
Treatment of heavy quarks in QCD
E. G. de Oliveira, A. D. Martin, M. G. Ryskin +1
We show that to correctly describe the effects of the heavy-quark mass, m_h, in DGLAP evolution, it is necessary to work in the so-called `physical' scheme. In this way, we automat…
Heavy quarkonium production in a strong magnetic field
C. S. Machado, F. S. Navarra, E. G. de Oliveira +2
It is well known that in noncentral heavy-ion collisions a transient strong magnetic field is generated in the direction perpendicular to the reaction plane. The maximal strength o…
Treatment of the infrared contribution: NLO QED evolution as a pedagogic example
E. G. de Oliveira, A. D. Martin, M. G. Ryskin
We show that the conventional prescription used for DGLAP parton evolution at NLO has an inconsistent treatment of the contribution from the infrared (IR) region. We illustrate the…
