EnergyMomentum and Angular Momentum in /line{Poincaré Gauge Theory\of Gravity and Physical Multiplets of Torsion Fields Weak Field Approximation
Abstract
In /line{Poincaré gauge theory of gravity proposed by Kawai, the generatois of /line{Poincaré and coordinate transformations and the multiplets of torsion fields are investigated in a weak field approximation. The relation of the generators to energymomentum and angular momentum in Kibbletype Poincaré gauge theory are clarified, on the basis of which the multiplets having positive simidefinite mass squares and giving positive definite total energy are classified. For the case alpha + 2 alpha / 3 !=q 0, (beta  2a/3)(gamma +3a/2)=0, new families of multiplets are found.
