Description:
Author(s): Ziwen Fu and Xu Chen We deliver lattice results for the I = 0 π π elastic s -wave scattering length calculated with the MILC N f = 3 flavors of the Asqtad-improved staggered fermions. The scattering phase shifts are determined by Lüscher’s formula from the energy-eigenvalues of π π systems at one center of mass frame and four m... [Phys. Rev.
