 21.02.2019 - Schools and workshops Recently, two TTP PhD students Kirill Kudashkin and Marco Bonetti attended the International School on "Modular forms, periods and scattering amplitudes" at the ETH Zürich. The School took place from 11.02.2019 to 15.02.2019. The goal of the school was to provide a common background to both physicists and mathematicians working in the field of scattering amplitudes and to introduce participants to new powerful tools for the evaluation and study of Feynman integrals. 23.04.2019 - TTP seminar We are pleased to inform you that the famous TTP institute's seminar is back on Wednesdays at 11:30 in 10/1. The first speaker is José Zurita. He will talk about minimal freeze-in and LHC friends, all about Dark Matter. The talk will take a place on 24th of April. More information about the topic of the talk might be found here . 09.02.2019 - TTP seminar Next TTP seminar will be given by Marvin Gerlach.He will give a short overview about non-relativistic QCD (NRQCD) and describe how a matching between QCD and NRQCD for a heavy four-quark vertex can be realized.Time and place of the event you can find in the details
