heal.abstract	Employing the eighth-order Hopping Parameter Expansion, we investigate the lattice regularized U(1)L ⊗ U(1)R scalar-fermion model in the phase with unbroken symmetry. We calculate two-, three- and four-point functions, out of which the renormalized masses and couplings, as well as the wave function renormalization constants can be deduced. The outcome is compared to existing Monte Carlo results and new regions of the bare parameter space are explored. Evidence is given about the multicritical structure of the model in the large Yukawa coupling region.	en
