摘要:
Important progress on the two-body scattering in the lattice QCD simulations has been made recently. Plenty of precise finite-volume energy levels are obtained both in the center of mass and moving frames, most of which are obtained at unphysical large pion masses. These precise finite-volume spectra contain valuable information of the nonperturbative dynamics of strong interactions. In this talk, I will discuss to use the chiral effective field theory to extract the physical properties of the resonances from those lattice energy levels. Special attention will be paid to the a0(980) from the pi-eta, KKbar and pi-eta’ coupled-channel scattering, the D*0(2400) from the D-pi, D-eta and Ds-Kbar, and the D*s0(2317) from the DK and Ds-eta scattering.
