Abstract:
While the Standard Model of particle physics has been remarkably successful, it leaves fundamental questions unanswered, driving the search for physics beyond the Standard Model (BSM). Low-energy experiments offer a promising path forward, but their success depends on advanced theoretical frameworks that address nuclear many-body challenges and high-order quantum effects.
In this talk, I will present recent theoretical advancements I have developed in three key BSM search areas: charged-lepton flavor violation (CLFV), dark matter, and forbidden beta decays. These include deriving previously missing components essential for interpreting CLFV experiments and dark matter direct detection, and introducing new operators for muon-to-electron conversion, which advance CLFV searches. I will also discuss ongoing research that leverages CLFV experiments, which are poised to improve precision by four orders of magnitude, to probe axion-like particles and provide novel constraints on their parameter space.
Finally, I will present the first nuclear-structure precision predictions for upcoming forbidden beta decay measurements in Israel and the US, alongside novel calculations of their high-order radiative effects, showing that, contrary to previous assumptions, unique forbidden decays can occur at zero momentum transfer. These findings also highlight an exceptional sensitivity to light new physics inaccessible in allowed decays, opening up a new regime of BSM physics within precision beta-decay searches, and sparking new experimental efforts in the US.
I will conclude by highlighting key open questions and demonstrating how integrating nuclear structure insights with advanced quantum calculations can expand the scope of BSM searches, paving the way for novel experimental opportunities and groundbreaking discoveries.
