The Center for Underground Physics (CUP) has operated at IBS for the last ten years. I want to review the perspectives of the CUP. In addition to CUP, I would like to state my personal view on Korean particle physics research briefly.
In collider experiments, an event is characterized by two distinct yet mutually complementary features: the global features' and thelocal features'. Kinematic information such as the event topology of a hard process, masses, and spins of particles comprises global features spanning the entire phase space. This global feature can be inferred from reconstructed objects. In contrast,...
Euclidean wormholes that arise in axion theories imply important phenomenological consequences in the context of the axion quality problem. In this work, we present an effective approach providing an analytic solution describing the structure of these axion wormholes. We identify the energy scales associated inside and outside the wormhole as the UV and IR regime of the wormhole respectively,...
I will discuss Higgs inflation and positivty bounds for dark matter in Higgs EFT or its extension.
Using 362/fb data sample of Belle II, we have studied B -> K \nu \bar{nu} decays at Belle II. In order to cope with final states with multiple neutrinos, we use two different methods for tagging, which are nearly statistically independent with each other. Combining the two methods, we find evidence for B -> K \nu \bar{nu} decays with 3.5\sigma.
