摘要：
Toponium production at future hadron colliders and its decay into two photons is investigated. Perturbative QCD corrections to the production cross section of eta(t) are calculated and found to be at the level of 50%. The QCD corrections to the branching ratio are incorporated and the two loop QCD potential is used for the calculation of the wave function at the origin. For LHC and a top mass of 110 GeV a eta(t) production cross section between 24 pb and 37 pb and a gammagamma branching ratio between 2.4 X 10(-5) and 3.6 x 10(-5) are predicted.
