Energy correlators are observables that have attracted attention from both collider physics and formal theory. In QCD jets, the two-point energy correlator offers a clean visualization of the confinement transition. I will present a calculation of the two-point correlator in the simplest "hard-wall" holographic model of confinement, with the aim of better understanding confinement through the...

Higgs couplings are essential probes for physics beyond the Standard Model (BSM) since they can be modified by new physics, such as through the Higgs portal interaction $|H|^2\mathcal{O}$. These modifications influence Higgs interactions via dimension-6 operators of the form $ \left(\partial |H|^2\right)^2$ and $|H|^6$, which are generally expected to be of comparable size. This talk discusses...

The geometry of field space governs on-shell scattering amplitudes in effective field theories. Extending previous geometric descriptions for scalars and gauge fields, I will discuss how we developed a framework that incorporates fermions into the geometric formulation of effective field theories. Utilizing this field-space geometry, we reorganize and simplify quantum loop corrections,...

Monopole, generically produced in any Unification theories, can also catalyze baryon decays at an unsuppressed rate, known as the Callan-Rubakov effect. This naturally provides a source of baryon number violation in both the early Universe and late Universe. For the first time, we propose a scenario to produce the primordial baryon asymmetry using the Callan-Rubakov effect and point out...
