Supervisor:

Department of Physics

Synopsis:

The subject introduces the student to the physics of Monte Carlo particle-collision generators, which bridge the gap between pure theory, represented by the Lagrangian of the Standard Model, and experimental reality, in which typically many particles are detected. The student will get acquainted with a wide range of methods of phenomenology of particle interactions, will understand the basic classification of processes from the point of view of the use of perturbation theory or approximate models for obtaining a matrix element, will gain insight into models of parton evolution called shower algorithms and will compare string and cluster hadronization. As part of the exercises, the student will be trained in the use of these software tools and will produce a more detailed report on the features of the chosen model.

Requirements:

Syllabus of lectures:

1. Random numbers and phase space integration

2. Calculation of matrix element (ME), specialized generators

3. Non-perturbative contribution to the collision event

4. Parton shower algorithm, its connection to ME, Sudakov correction

5. String and cluster model of hadronization, color rearrangement

6. Generation of heavy ion collisions
