  We present an extension to the jet area-based pileup subtraction for both jet
kinematics and jet shapes. A particle-level approach is explored whereby the
jet constituents are corrected or removed using an extension of the methods
currently being employed by the LHC experiments. Several jet shapes and nominal
jet radii are used to assess the performance in simulated events with pileup
levels equivalent to approximately 30 and 100 interactions per bunch crossing,
which are characteristic of both the LHC Run I and Run II conditions. An
improved performance in removing the pileup contributions is found when using
the new subtraction method. The performance of the new procedure is also
compared to other existing methods.
