# Integrand reduction techniques at one and higher loops

#### Integrand reduction techniques at one and higher loops

- Event time: 2:00pm
- Event date: 9th May 2014
- Speaker: Tiziano Peraro (Formerly School of Physics & Astronomy, University of Edinburgh)
- Location: Higgs Centre Seminar Room, Room 4305, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

I will talk about recent developments in integrand reduction techniques for the computation of loop integrals. I will present the integrand reduction via Laurent expansion method for one-loop amplitudes, implemented in the public library Ninja. I will show some phenomenological applications to processes relevant for LHC, obtained using an automated framework which combines Ninja and the one-loop package GoSam. I will also present an algebraic framework which can be used to extend integrand reduction techniques to higher loops.

### About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
