Abstract: Given two possibly unbounded selfadjoint operators A and G such that the resolvent sets of AG and GA are non-empty, it is shown that the operator AG has a spectral function on IR with singul...
Charmonium correlation and spectral functions at finite temperature
Charmonium correlation spectral functions finite temperature

We study the properties of charmonium states at finite temperature in quenched QCD on isotropic
lattices. We measured charmonium correlators using non-perturbatively O(a) improved clover
fermions on...
