PY - 2011 DO - 10.1103/PhysRevD.83.094011 SN - 1550-7998 UR - https://hdl.handle.net/20.500.14352/44831 T2 - Physical review D AB - We calculate the pion-pion elastic scattering phase shifts for pion masses from the chiral limit to values of interest for lattice studies. At low energies, we use the standard Chiral Perturbation Theory expressions to one and two loops. In addition,...
