Description
Measurements of jet substructure have augmented substantially the scope
of jet quenching studies by arguably giving experimental access to
single splitting jet properties and possibly allowing for the
identification of QGP response contributions to a jet. We show that jet
substructure observables provide a path to measure how quenched a jet is
without the need for comparison with other states in the event (eg, an
electroweak boson). By exploring the flexibility of the Soft Drop
procedure, we identify cuts (ie, Soft Drop parameters) that act as a,
background insensitive, jet quenching classifier. This, so far elusive,
classification allows for the robust identification of strongly quenched
jets from which stringent constrains on jet quenching mechanisms can be
extracted.
