Compact expression for a bilinear combination of Dirac spinors in terms of world tensors
R. N. Rogalev Institute for High Energy Physics
Abstract:
A compact expression is obtained for the product of two Dirac spinors in the form of a linear combination of 16 Dirac matrices. A convenient form of expression of the results, permitting its use for analytic calculations of the amplitudes of many-particle processes, is found. It is shown that a bilinear combination of Dirac spinors can be expressed in terms of the 4-momentum vectors and spins of the corresponding particles together with a common phase factor.
