Power up your logarithm: the large impact of 'subleading' terms



Cross-sections in perturbative QCD are plagued by large  corrections from soft and collinear radiation. The most singular  terms are known to be universal, which allows their resummation  to all orders in the coupling, hereby curing the cross-section of  the large uncertainties. In this talk, I will give a broad  introduction as to how these large corrections arise, how  resummation solves the issue, and whether we can expect the same  universal structure for a class of next-to-singular contributions. We also discuss their numerical impact.
