Abstract: Background: Previous theoretical work has found that the effective mass of the nucleon influences the excitation energy of the isoscalar giant quadrupole resonance (ISGQR).Purpose: The present paper presents an attempt to constrain the effective mass… read more here.

Abstract: We use the infinite volume reconstruction method to calculate the charged and neutral pion mass difference. The hadronic tensor is calculated using lattice QCD and then combined with an analytic photon propagator, and the mass… read more here.
