Description
Strong medium effects seen in the suppression of R_{CP} in RHIC
data are also visible in the recent LHC data. Constructing jets explictly
in heavy ion collisions, similar ratios for jets have also been
constructed, and display suppression as well. The latter are
theoretically more appealing for studies of jet quenching. However, the
corresponding results appear to depend on cone radius, and perhaps
background subtraction. We propose a new observable, called zeal, to
characterize jets for analysis in heavy ion collisions. Zeal measures how
the thermal medium affects the multiplicity and distribution of energetic
particles in a jet, and is designed to be minimally dependent on cone
radii or the underlying background. Toy models are used to illustrate
these properties.
