Tagging boosted hadronic objects with dynamical grooming

Understand

We evaluate the phenomenological applicability of the dynamical grooming technique, introduced in [1], to boosted W and top tagging at LHC conditions.

• An extension of our method intended for multi-prong decays with an internal mass scale, such as the top quark decay, is presented.
• First, we tackle the reconstruction of the mass distribution of W and top jets quantifying the smearing due to pileup.
• When compared to state-of-the-art grooming algorithms like SoftDrop and its recursive version, dynamical grooming shows an enhanced resilience to background fluctuations.
