Description

Identifying the flavour of the experimentally reconstructed hadronic jets is critical to pinpoint specific scattering processes and reject background processes. Jet measurements at the LHC are almost universally performed using the anti-$k_T$ algorithm, however no approach exists to define the jet flavour for this algorithm that is infrared and collinear (IRC) safe. In this talk, we propose a new approach that is IRC safe to all orders in perturbation theory and can be combined with any definition of a jet. We test the algorithm in $e^+e^-$ and $pp$ environments, and as an application we compare our approach to other algorithms for the $Z$+$b$-jet/$Z$+$c$-jet production.
