Study of the scalar and pseudoscalar meson mass spectrum above the QCD chiral phase transition, using an effective Lagrangian approach
An effective Lagrangian is used to compute scalar and pseudoscalar meson masses above Tc in Nf=2+1 QCD and tested against lattice screening masses extracted from chiral susceptibilities for evidence of persistent U(1)A breaking.
