| الوصف: | Identifying the flavour of reconstructed hadronic jets is critical for precision phenomenology and the search for new physics at collider experiments, as it allows to pinpoint specific scattering processes and reject backgrounds. 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. We propose a new approach, a flavour dressing algorithm, 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 $\mathrm{e}^+\mathrm{e}^-$ and $\mathrm{p}\mathrm{p}$ environments, and consider the $\mathrm{p}\mathrm{p} \to \mathrm{Z}+\mathrm{b}\text{-jet}$ process as a practical application. Comment: 6 pages, 2 figures. v2: revision of original algorithm due to infrared and collinear safety issues |
