Hello,

I’m Seungho Han.

I am an experimental particle physicist currently based at Kyoto University, working on neutrino physics and neutrino–nucleus interactions.

I am broadly interested in what neutrinos can reveal about physics beyond the Standard Model, particularly the origin of the exceptionally small masses of active neutrinos and the possible connection between leptonic CP violation and the baryon asymmetry of the Universe. Experimentally, I pursue these questions through measurements of neutrino oscillations, in particular the neutrino mass ordering and CP violation in lepton mixing, using accelerator long-baseline and atmospheric neutrino experiments.

A complementary focus of my research is the hadronic final state of neutrino–nucleus interactions. Understanding these interactions is essential for reducing systematic uncertainties in oscillation measurements, but their underlying nuclear dynamics are also an interesting subject in their own right. I study neutrons, protons, and pions as probes of nuclear effects and as additional information for neutrino reconstruction, using techniques that enable increasingly detailed measurements of low-energy hadronic final states.
