Threshold resummation for the inclusive-hadron cross section in pp collisions
We study the resummation of large logarithmic perturbative corrections to the partonic cross sections relevant for the process pp→hX at high transverse momentum of the hadron h. These corrections arise near the threshold for the partonic reaction and are associated with soft-gluon emission. We perfo...
