Description
Semi inclusive deep inelastic scattering (SIDIS) process can provide insight into
the internal structure of hadrons and also the dynamics of fragmentation
of parton into hadrons. Often the perturbative predictions contain large
threshold logarithms that need to be resummed to all orders in order
make the predictions stable. In this work, we develop a formalise
that will allow us to resum not only leading threshold logarithms but also
subleading ones to all orders. We use renormalisation group equations and
sudakov differential equations to obtain the results that are sensitive to these
logarithms. We study their numerical impact at SIDIS experiments by performing
the computations in two dimensional Mellin space. Our results improve the
predictions.
