Abstract
We investigate Non-Hermitian quantum field theoretic model with interaction in 6 dimension. Such a model is PT-symmetric for the pseudo scalar field . We analytically calculate the 2-loop function and analyse the system using renormalization group technique. Behavior of the system is studied near the different fixed points. Unlike theory in 6 dimension theory develops a new non trivial fixed point which is energetically stable.
