Progress on double-logarithmic large-x and small-x resummations for (semi-)inclusive hard processes

Autor: Vogt, A., Kom, C. H., Presti, N. A. Lo, Soar, G., Almasy, A. A., Moch, S., Vermaseren, J. A. M., Yeats, K.

Over the past few years considerable progress has been made on the resummation of double-logarithmically enhanced threshold (large-x) and high-energy (small-x) higher-order contributions to the splitting functions for parton and fragmentation distrib

We discuss the large-x behaviour of the splitting functions P_qg and P_gq and of flavour-singlet coefficient functions, such as the gluon contributions C_2,g and C_L,g to the structure functions F_2,L, in massless perturbative QCD. These quantities a

We present the coefficient functions for deep-inelastic scattering (DIS) via the exchange of a scalar phi directly coupling only to gluons, such as the Higgs boson in the limit of a very heavy top quark and n_f effectively massless light flavours, to
