CP violation in unpolarized e^+ e^- to charginos at one loop level
arXiv:0704.2165 · doi:10.1103/PhysRevD.76.036001
Abstract
We study CP violation in e^+ e^- to \tildeχ_i^+\tildeχ_j^- in the framework of the MSSM. Though the cross section of this process is CP-even at the tree level even for polarized electron-positron beams, we show that it contains a CP-odd part at the one loop order and there are CP-odd observables that can in principle be measured even using unpolarized electron-positron beams. The relevant diagram calculations are briefly discussed and the results of selected (box) diagram computations are shown.
