Monte-Carlo Generator Photon Jets for the process e+e- -> gamma gamma

Understand

Monte-Carlo generator with photon jets radiation in collinear regions for the process \eegg is described in detail.

• Radiative corrections in the first order of $\alpha$ are treated exactly.
• Large leading logarithmic corrections coming from collinear regions are taken into account in all orders of $\alpha$ by applying the Structure Function approach.
• Theoretical precision of the cross section with radiative corrections is estimated to be 0.2%.
