Description
The N-jettiness is a useful resolution variable to distinguish between events
with a different number of jets in the final state. It has
been successfully employed in slicing calculations for colour singlet processes at
NNLO and its resummation forms the basis for the Geneva approach to matching
NNLO calculations to parton showers. I will discuss the extension of the zero-jettiness
resummation for colour-singlet production to include the production of heavy
coloured particles at the LHC. Having derived a factorisation theorem for the observable
in this process, we have resummed large logarithms up to approximate NNLL' accuracy.
I will describe the resummation framework we have developed and outline
future applications to slicing calculations and NNLO+PS event generation.
