Practical jet flavour through NNLO

An infrared and collinear (IRC) safe definition of the partonic flavour a jet is vital for precision predictions quantum chromodynamics at colliders. Jet definitions have been presented in literature, but they are typically defined through modification algorithm to be sensitive every stage clustering. While this does ensure that sum flavours IRC safe, flavour-sensitive clustering procedure difficult apply realistic data. We introduce distinct novel approach can applied any collection partons by algorithm. Our all remain after Soft Drop grooming, reclustered with Jade prove prescription next-to-next-to-leading order (NNLO), so interface most precise fixed-order calculations jets available present. validate safety numeric codes further show generalised kT fails NNLO.
