Abstract
Several methods for the determination of the trace of the product of an arbitrary number of Pauli matrices are established. Formulae are derived for the evaluation of various types of products of two traces when terms of the type σi1σi2...σin occur in both of them. Expressions are found for the product of two different traces and the square of the trace of an arbitrary number of Pauli matrices. Similar formulae are obtained when Dirac matrices occurring as\(\sum\limits_{i = 1}^5 {\gamma _i A_i } \) are considered instead of Pauli matrices. From this all previous results in which γ5 has been considered separately are recovered. A useful identity for traces involving either Pauli or Dirac matrices is given.
