Abstract

Feynman integrals are important for nearly every computation in perturbative high-energy physics. They are required in order to extract predictions from the theory beyond the leading perturbative order. As a consequence, they are important in many areas, e.g. collider physics, gravitational waves, the evolution of the universe, lattice gauge theory, string theory, and pure mathematics. In this talk, I will discuss a highly efficient machinery for computing state-of-the-art Feynman integrals. This includes integration-by-parts reduction, (canonical) differential equations, the method of regions, and the Feynman parameter method. All techniques are introduced pedagogically through simple examples.

Bio

Christoph Dlapa received his Bachelor's degree from Graz University of Technology in 2016, his Master's degree from ETH Zurich in 2018, and completed his PhD at the Max Planck Institute for Physics in 2021. Since then, he has been working as a postdoctoral fellow at DESY Hamburg. His research focuses on Feynman integrals, differential equations, and their applications in gravitational wave physics and collider physics.

The seminar will be broadcasted online by Zoom. 

Interested people are free to join, without registration in advance.
