Scattering Amplitudes in Quantum Field Theory (WS17)
Lecturers
J.Prof. Dr. Harald Ita and Dr. Samuel Abreu
Dates
- Lecture: 2 hours, Tue 12-14, SRII; start: 16.10.2017
- Tutorial: 2 hours, Fr 12-14, SRII; start in second lecture week
Content
- Methods for analytic computation of scattering amplitudes (spinor helicity formalism, recursion relations)
- Properties of scattering amplitudes (IR singularities, cancellation of unphysical singularities)
- Integral relations (algebraic and geometric methods)
- Unitarity method (Landau equations, reduction of integrands of loop amplitudes)
- Extra material: differential equations method
For Bachelor-Students
The lecture is suitable as supplementary or elective course. The class aims at MSc-level, however, we can as well provide a self-contained discussion for motivated BSc students.
Prerequisits
Quantum Mechanics, QFTI
Requirements for Academic Record
- regular participation in the tutorials, including solutions to 75% of the homework problems.
- in case an exam ( "Prüfungsleistung") is required, an oral exam will be offered. Prerequisite is the successful participation in the tutorials.
Further details will be given in the lecture/tutorials.
