Description
In addition to the applicability of lattice simulations in dense medium, two-color QCD world has another advantage that diquark dynamics can be directly observed since diquarks are color-singlet for Nc=2. In this talk, first I explain how a chiral model, i.e., linear sigma model, for Nc=2 and Nf=2+1 is constructed. Then, based on it, I present diquark mass modifications at finite temperature particularly focusing on the mass hierarchy of [sq] and [qq] diquarks, from the viewpoints of chiral restoration and U(1) anomaly effects. Finally, I also discuss connections to singly heavy baryons in our real-life world in hot medium.
