Low Scale Quark Lepton Unification: From the LHC to Mu2e

Abstract: Although the Standard Model (SM) has been remarkably successful in describing the electromagnetic, weak and strong interactions, it is highly unlikely to be the final theory of nature. In particular, the origin of neutrino masses, the observed matter–antimatter asymmetry, and several other observations remain unexplained within the SM framework. Quark-Lepton unification provides a unique theoretical framework for physics beyond the Standard Model where one predicts massive neutrinos. In this talk, I will explore the possibility of realizing quark–lepton unification at low energies. I will focus on a TeV-scale framework in which neutrino masses are generated through the inverse seesaw mechanism. This framework predicts a rich spectrum of new particles, including additional neutral and charged Higgs bosons, heavy right-handed neutrinos, and leptoquarks. I will discuss the prospects for probing this framework at the Large Hadron Collider, highlighting the unique signatures arising from its scalar sector. I will also discuss how low-energy searches for charged lepton flavor violation can probe parameter space beyond the reach of current or future collider experiments. Together, collider searches and low-energy experiments such as Mu2e at Fermilab can provide complementary ways to test the quark–lepton unification framework in the near future.
