HIGH-ENERGY TESTS OF THE LEFT-RIGHT-SYMMETRICAL ELECTROWEAK MODEL

The left-right symmetric extension of the Standard Model, based on SU( 2)(L) x SU(2)(R) x U(1)(B-L) symmetry, has many predictions one can te st at TeV-scale accelerators. These include the existence of new heavy weak bosons W-2 and Z(2) and right-handed neutrinos, as well as of tr iplet Higgses. We discuss various direct tests of the basic ingredient s of the left-right symmetric model, as well as of its supersymmetric version, in e(-)e(-), e(-)gamma and gamma gamma collisions at high ene rgies.
