19. New Fermions and the One-Loop Effective Action

Andrei Angelescu (University of Nebraska-Lincoln)

Recently, there has been a growing interest in developing functional methods for calculating the Wilson coefficients of dimension-6 operators arising from integrating out heavy new fields at one loop. In this talk, we discuss the particularities of this method when applied to Vector-Like Fermions (VLFs), and illustrate it for a simple VLF model.

14. Distinguishing Lepton Flavor Violating Signals from Neutral and Doubly-Charged Scalars at Future Lepton Colliders

Many new physics scenarios beyond the Standard Model (SM) often
necessitate the existence of new neutral and/or doubly-charged scalar fields,
which might couple to the SM charged leptons in a flavor violating way,
while evading all existing constraints. At future lepton colliders like CLIC
the neutral and doubly-charged scalar might induce the lepton flavor
violating (LFV) signals...

5. Probing a Light Leptonic Scalar at the LHC

If a light neutral beyond standard model scalar $\phi$ couples exclusively to the active neutrinos, then the dominant production channel of such a light neutral scalar at the LHC is through the fusion of two same-sign $W$ bosons. As $\phi$ decays only into neutrinos, the production of $\phi$ at LHC induces the signal of same-sign dilepton plus two forward jets plus missing transverse energy....

15. Flavor Physics in Left-Right Symmetric Model

I will present the results of our analysis on flavor physics in Left-Right Symmetric Model which utilize vector-like fermions to generate quark and lepton masses via universal see-saw mechanism. A parity symmetric version is studied. New contributions to meson mixing and lepton universality violation will be presented. The possibilities of explaining B-anomalies in this context will also be explored.
