title: Scaling fields and pressure mixing in the Widom-Rowlinson model.
abstract: We address the issues of scaling fields and of pressure mixing in the penetrable sphere model. This model has an exact symmetry locus from which analytical results may be derived. Based on exact results, we demonstrate that the scaling fields are analytic functions of temperature and chemical potential only. We conclude that there is no pressure mixing in this model. Our findings are in accord with numerical simulations for the same model.
