  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. In addition, we asses the discriminating
power of dynamical grooming to distinguish W (top) jets from QCD ones by
performing a two-step analysis: introduce a cut on the groomed mass around the
W (top) mass peak followed by a restriction on the N-subjettinnes ratio
$\tau_{21}$ ($\tau_{32}$). For W jets, the out-of-the-box version of dynamical
grooming, free of ad-hoc parameters, results into a comparable performance to
SoftDrop. Regarding the top tagger efficiency, 3-prong dynamical grooming, in
spite of its simplicity, presents better performance than SoftDrop and similar
results to Recursive SoftDrop.
