DESCRIPTION:Speakers: Bithika Karmakar (Institute of Physics Belgrade)\nTy
 pically\, the bulk properties of Quark Gluon Plasma (QGP) are studied usin
 g the low-pt data. However\, the high-pt probes can also serve as powerful
  tomography tools\, since they are sensitive to global QGP features\, such
  as different temperature profiles or initial conditions. In this study\, 
 we try to determine if it is possible to constrain the η/s of the medium 
 formed in the heavy-ion collisions using the high-pt data/theory. We assum
 e three different parametrizations of (η/s)(T) and compute the high-pt RA
 A and flow coefficients v2\, v3\, and v4. Our results demonstrate that the
  high-pt data can not distinguish between different (η/s)(T) assumptions 
 when the evolution is constrained to reproduce the low-pt data. As a secon
 d approach\, we utilize our dynamical energy loss model to compute the que
 nching strength (q̂/T^3) and then transform it into the (η/s)(T) of the 
 evolving medium. The temperature dependence of (η/s) computed in this app
 roach agrees surprisingly well with the (η/s)(T) inferred through state-o
 f-the-art Bayesian analysis of the low-pt data.\n\nhttps://events.saifa.rs
