Energy loss by particles inside a medium is an important quantity that helps characterize the medium. In this project, numerical estimates of the energy loss of fast particles inside a plasma medium dominated by quantum chromodynamic interaction will be made.

Tasks

1. Radiative energy loss of gluons inside a gluonic plasma. Review of the Gunion-Bertsch formula and its corrections. 2. A brief discussion of the associated kinematics. 3. A relationship between energy loss and transport coefficients from a transport equation perspective.

Preliminary schedule by topics/tasks

Week 1: There will be several lectures covering the topics; Weeks 2-3: Review of the topics and the tasks given; Weeks 4-5: Preparing a report.

Required skills

The participant must be familiar with calculating the tree-level Feynman diagrams. Familiarity with LaTeX and proficiency in English are necessary. Some familiarity with Mathematica will be an added advantage.

Acquired skills and experience

The participant will be acquainted with various methods to estimate energy loss in a QCD plasma. She/he will learn about the connection between the transport coefficients and energy loss of high energy particles. The participant is also expected to increase skills in performing symbolic and numerical computations using Mathematica.
