# Higher Derivative Scalar Field Theory in the First Order Formalism

@article{Kruglov2006HigherDS, title={Higher Derivative Scalar Field Theory in the First Order Formalism}, author={Sergey I. Kruglov}, journal={arXiv: High Energy Physics - Theory}, year={2006} }

The scalar field theory with higher derivatives is considered in the first order formalism. The field equation of the forth order describes scalar particles possessing two mass states. The first order relativistic wave equation in the 10-dimensional matrix form is derived. We find the relativistically invariant bilinear form and corresponding Lagrangian. The canonical energy-momentum tensor and density of the electromagnetic current are obtained. Dynamical and non-dynamical components of the…
