Calculating Jet Shape Modifications and Jet Energy Loss in Heavy Ion Collisions Using Soft-Collinear Effective Theory

Highly energetic jets as well as a hot, dense medium are produced in ultra-relativistic nucleus-nucleus collisions, and jets provide a unique hard probe of the medium through the study of jet modifications. More specifically, the jet shape gives the transverse energy profile inside jets and it is sensitive to the details of the medium properties. In this talk I will discuss the study of jet shape modifications in lead-lead collisions using soft-collinear effective theory, with Glauber gluon interactions in a realistic hydrodynamic medium. Also, I will discuss the closely related jet energy loss within the same consistent framework. In the end I will compare the calculations with the measurements at the LHC with nucleon-nucleon center of mass energy at 2.76 TeV with good agreement.
