A quadratic curvature Lagrangian of Pawłowski and Rcaczka: a finger exercise with MathTensor
arXiv:gr-qc/9601002
Abstract
Recently Pawłowski and Rcaczka proposed a unified model for the fundamental interactions which does not contain a physical Higgs field. The gravitational field equation of their model is rederived under heavy use of the computer algebra system Mathematica and its package MathTensor.
