We present a lattice quantum chromodynamics(QCD)simulation with 2+1+1 flavor full QCD ensembles using near-physical quark masses and different spatial sizes L,at a～0.055 fm.The results show that the scalar and pesudoscalar 2-point correlator with a valence pion mass of approximately 230 MeV become degenerated at L ≤ 1.0 fm,and such an observation suggests that the spontaneous chiral symmetry breaking disappears effectively at this point.At the same time,the mass gap between the nucleon and pion masses remains larger than ΛQCD in the entire L ∈[0.2,0.7]fm range.
