A NEW KERR-NEWMAN-DE SITTER EXACT SOLUTION OF THE POINCARE GAUGE-THEORY OF GRAVITATION

We present a new exact solution of the Poincare gauge theory of gravit ation with the Kerr-Newman-De Siller metric and nonzero torsion. The m etric and torsion of the solution ari characterized by four arbitrary parameters: mass m, angular momentum j, electric charge q, and effecti ve cosmological constant L. All three irreducible components of the to rsion are nonzero In particular the totally antisymmetric torsion (the only part of the torsion which is coupled directly to spin-1/2 fermio ns) is nonvanishing. The solution is obtained front a previously known one with the help of a special discrete transformation.
