[en] Study of correlation functions of hadronic currents provides information regarding interquark interaction as a function of their spatial separation. Equal time point to point spatial correlation function of hadronic currents is considered here with a specific ansatz for the vacuum in terms of the quark fields. To extract hadronic properties at finite temperatures, a phenomenological parametrisation of the correlation function is done using spectral density function with the mass, coupling and a threshold for continuum, all the three parameters being temperature dependent
