Two-loop RGEs from geometry / Naterop, Luca (speaker) (University of Zürich and PSI)
RGE calculations in EFTs can carried out efficiently in a geometric picture, where field redefinitions are just coordinate changes. Building on an old method introduced by ’t Hooft in 1973, we extend the geometric formulation for scalar theories to the two-loop order and derive the counterterms which renormalize the theory at two loops.

Exploration with LHCb: from unseen to rare / Shchutska, Lesya (speaker) (EPFL - Ecole Polytechnique Federale Lausanne (CH))
Abstract Large collected dataset by the LHCb experiment, combined with unconventional ideas, allows more and more rare decays mediated by flavour-changing neutral current (FCNC) transitions, possible only at the loop level in the Standard Model of particle physics, to be put under scrutiny. In this seminar we report on the observation of a decay with b->s gamma transition, test FCNC in the up-quark sector, and use FCNC transitions to look for signs of lepton flavour violation [...]

Fixed points of 4D quantum field theories - and what they can do for us / Litim, Daniel (speaker) (University of Sussex)
Fixed points in quantum and statistical field theory are responsible fora large variety of phenomena. Low energy fixed points often entail quantum,thermal, or topological phase transitions, (chiral) symmetry breaking,or the generation of mass, while high energy fixed points are at the root ofa fundamental definition of QFT such as in asymptotic freedom or safety.In this talk, I discuss the prospects for UV and IR fixed points in general4d quantum field theories.
