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 g̃g̃ → tt̄. Because the top quark is heavy, the masses of the superpartners of the lefthanded and right-handed top quarks can be very different such that a parityviolating observable can be induced in the tree level production process. We discuss the phenomenology of this parity violatiing asymmetry at the CERN Large Hadron Collider.
