Signatures of the light gluino in the top quark production

If a light gluino, with a mass of the order of GeV, exists in the minimal supersymmetric extension of the Standard Model, then it can contribute to the production rate of the top quark pairs at hadron colliders via the process gluino + gluino --> t + tbar. Because the top quark is heavy, the masses of the superpartners of the left-handed and right-handed top quarks can be very different such that a parity-violating observable can be induced at the tree level. We discuss the phenomenology of this parity violating asymmetry at the CERN Large Hadron Collider.
