Understanding wide jet suppression in data through the hybrid strong/weak coupling model

Understand

We explore a set of jet substructure observables that use grooming techniques such as the Soft Drop procedure by performing simulations with the hybrid strong/weak coupling model for jet quenching.

• The results obtained for the observables presented in this proceedings, namely the number of Soft Drop splittings, or $n_{\rm SD}$, and the sharing momentum distribution $z_g$ for different angular cuts between the two main branches in a jet, can be easily understood as arising from the fact that among all the jets with a given jet $p_T$, those jets which are wider in opening angle, meaning that they have a higher jet mass and come from showers featuring more splittings, tend to lose more energy than the narrower jets.
• We comment on the comparison to data from ALICE and CMS, and point out the caveats arising from the consideration of smearing effects due to the presence of a large fluctuating background.
