Modern Methods for Particle Scattering
The purpose of this course is to give the students an insight into various conceptual, theoretical, practical aspects of particle scattering computations.
Various recent developments in such computations as well as in related topics will be discussed and we will see how to employ different modern techniques to simplify calculations maximally. We will also in the course explore hints of a deeper underlying structure governing the structure of amplitudes.
MSc Programme in Physics
The course will begin with an introduction to practical field theory computations, and discuss many related topics, such as numerical methods for computation, recursion techniques, loop amplitudes, unitarity, spinor-helicity techniques, color-ordering formalism, factorization of amplitudes in various limits, also it is the aim to cover different computational settings than standard field theory; for example effective field theory techniques and for example practical uses of string theory results. The course will also give a brief introduction to concepts such as scattering cross-section computation and discuss how such results are used in experiments
At the end of the course the students should
- Have gained a more solid background in field theory and for example have been giving a proper introduction to various aspects of more advanced computations.
- Have gained insight in various numerical methods for computation.
- Have been introduced to spinor-helicity techniques and color-ordering formalisms.
- Know about physical factorization limits.
- Have been introduced to the various modern recursive techniques for amplitudes.
- Have knowledge of how to do cross-section computations using amplitude results.
- Have gained basic knowledge about loop computations and be able to use unitarity techniques.
This course builds on the knowledge from quantum mechanics, quantum field theory, special and general relativity and elementary particle physics. The course will provide the students with a competent background for further studies within this research field, i.e. a M.Sc. project in particle phenomenology and theoretical high-energy physics. It will also provide those that plan to continue into experimental high-energy physics or cosmology the necessary background for various computations. This course will provide the students with some mathematical tools that have application in a range of fields within and beyond physics.
