About me: Within the past few years, my research has been on the structure of hadrons — composite particles made of quarks (and gluons) — particularly in the case where they are probed with large center-of-mass (CM) energies. In this regime, Quantum Chromodynamics (QCD), which is the gauge field theory describing strong interactions, is not only perturbative but also simplifies in a fairly convenient fashion, allowing one to study complicated hadron distribution functions from relatively clean amplitudes of a quark-antiquark dipole scattering with a large, dense target. This has led to various theoretical predictions including the power-law growth in sea quark and gluon distributions at fairly high CM energies, but the growth stops as the CM energy becomes large enough, in the phenomenon famously known as gluon saturation.

More recently, similar method has been generalized to account for spin dependence. This opens a new avenue to gain a complete understanding of the spins of quarks and gluons inside hadrons, and ultimately to learn how they add up to the hadron’s fixed, half-integral spin. In the near future, I plan to examine the spin distributions in this regime in various spin bases, together with related objects like odderon amplitudes, which result from the same hadronic operators.

I am open to collaborate on various research topics where my experience could be useful. Please stop by and talk. My office is behind the third door to the left in Room 504, MhMk Building.
