On Einstein's super symmetric tensor and the number of elementary particles of the standard model

We present an invariant characterization of a curved super symmetric spacetime in terms of scalers constructed from the Riemannian and metric tensors of general relativity. The corresponding number of independent components found that way leads to results consistent with the number of massless states of the Heterotic string theory, namely 8064 as well as the phenomenology at the energy scale of the standard model, i.e. 60 experimentally verified particles plus two conjectured particles.
