Taylor expansion of the thermodynamic potential in powers of the (baryo)chemical potential µ B is a well-known method to bypass the Sign Problem of Lattice QCD. Due to the difficulty in calculating the higher order Taylor coefficients, various alternative expansion schemes as well as resummation techniques have been suggested to extend the Taylor series to larger values of µ B . Recently, a way to resum the contribution of the first N charge density correlation functions D 1 , . . . , D N to the…
