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...
Many searches for New Physics and precision measurements in QCD involve the study of jet substructure for final state hadrons. While traditionally the state of the art for studying jets at particle colliders have been event shape observables, recently it has been better understood that measuring correlation functions of energy flow operators inside a jet is in fact a very powerful tool for...
One of the most important goals of the precision collider physics program is to push beyond the sub-percent accuracy of the current top quark mass measurement. This involves looking for observables that are both sensitive to the top mass and can be brought under theoretical control. Satisfying both these criterion at the LHC is a challenging task due to contributions from soft physics and the...
