Scaling function for the energy density correlation at large momentum

The static energy-density correlation function S²(0)S²(x)–S²² is calculated in the critical region for theS⁴ Ginzburg-Landau-Wilson model at short distances and for nonzero field. Short distance expansion is used and its structure for more complex vertex functions is given. Goldstone mode singularities present at the magnetization curve are taken into account. The main application is given in the theory of polymer solutions. Here, S²(0)S²(x)–S²² becomes the Fourier transform of the densitydensity correlation.
