Query: Perspectives in Small Systems : Heavy Quarks and HBT Radii   Recent observations of QGP-like phenomena in small collision systems like p+p
and p+A collisions have questioned our understanding of the basic paradigms of
high energy heavy-ion physics. A brief discussion of these new aspects in small
systems which in turn influence our understanding of hard probes like heavy
quarks has been provided. Furthermore, a closer observation of the two-particle
Hanbury-Brown Twiss (HBT) interferometry measurements provide new insights in
our understanding of medium-like phenomena in small systems. An outlook of
future goals and measurements is also made.
