摘要：
We study the chiral phase transition of the two-flavor Nambu-Jona-Lasinio model in a sphere with the MIT boundary condition. We find that the spherical MIT boundary condition results in stronger finite size effects than the antiperiodic boundary condition. Our work may be helpful to study the finite size effects in heavy-ion collisions in a more realistic way.
