Felix Yu,Mainz, [HET Seminar] Exploring Effective Theories of Gauged Chiral Symmetries at the LHC and Beyond

Thursday 22 Jan 2026, 11:00 → 13:00 US/Eastern

Small Seminar Room

I discuss theoretical issues with constructing effective theories of gauged chiral symmetries, taking a quark-universal U(1)_B symmetry as an example.  I will review the phenomenology of the Z-Z’-photon vertex and point out novelties regarding a non-renormalization theorem and connections to electroweak loop calculations and dimensional regularization.  I will also present the collider signatures from the exotic scalar sector and the characteristic nature of non-decoupling chiral matter.  I also comment on the phenomenological impact of kinetic mixing and an improvement in the theoretical treatment of nearly mass-degenerate decaying states.
