The QCD corrections to scalar top pair production in photon-photon collisions

The complete QCD corrections to the scalar top quark pair production via $γγ$ fusion in parent $e^{+}e^{-}$ collider are calculated in the Supersymmetric Model. The various origins of corrections are discussed. We find that the correction due to gluino exchange is smaller than that due to conventional gluonic contribution, and the contribution due to squark quartic interactions is much smaller. Moreover, the dependences of the corrections on the masses and the mixing angle of the supersymmetric particles are also investigated.

Electroweak corrections to the $H\to t\bar{t}$ decay rate

The electroweak corrections at one-loop level to the process $H\rightarrow t{\bar t}$ are calculated, especially the fresh top mass value announced recently by CDF is concerned. For $M_H < 1. TeV$ where a perturbative calculation is valid, the corrections themselves would gain a few to 20 percent increment in the decay width as the Higgs mass $M_H$ is increasing within the region, but they are in opposite direction to the QCD ones. If the electroweak and QCD corrections are concerned in the meantime, the resultant decay width of the mode yields a reduction about a few percent of the tree level one.
