Abstract
The phase structure and the infrared behaviour of the Euclidean 3-dimensional symmetric ghost scalar field has been investigated in Wegner and Houghton's renormalization group framework, including higher-derivatives in the kinetic term. It is pointed out that higher-derivative coupling provides three phases and leads to a triple point in that RG scheme. The types of the phase transitions have also been identified.
