QCD Casimir effect : Application to chiral partners of hadrons

量子物理学・ナノサイエンス第273回セミナー

概要

The usual Casimir effect is a zero-point energy shift induced by two parallel plates, which is a perturbative phenomenon in quantum electrodynamics (QED) (particularly, photon fields). On the other hand, in the quantum chromodynamics (QCD) vacuum including quarks and gluons (and also hadrons), the Casimir effect should be affected by the nonperturbative properties such as the spontaneous chiral symmety breaking, color confinement, and instantons. Recently, similar phenomena in the pure Yang-Mills theory were observed from lattice simulations [1,2,3], so that the "QCD Casimir effect" would also attract much attention in the future. In this talk I will discuss our recent studies [4,5] about the Casimir effects for chiral partners in hadrons such as nucleons and D mesons.
