Probing Heavy New Physics at the Precision Frontier with Effective Field Theory — •Peter Stangl — Johannes Gutenberg-Universität Mainz

The Standard Model of particle physics successfully describes all known elementary particles, yet it leaves fundamental questions unanswered, from the origin of neutrino masses and the Higgs hierarchy problem to the puzzling patterns in particle masses and mixings. With direct searches at the LHC having reached their energy limit without discovering particles beyond the Standard Model, precision measurements offer a powerful complementary approach: heavy new particles, even if beyond direct reach, modify the interactions of known particles in measurable ways. I will discuss how Effective Field Theory methods combined with precision data from flavour physics, electroweak measurements, and collider observables can be used to systematically search for these subtle signatures of physics beyond the Standard Model.
