Effective photon spectra for Photon Colliders
/ Authors
/ Abstract
The luminosity distribution in the effective γγ mass at a photon collider has usually two peaks which are well separated: the High energy peak with mean energy spread about 5 − 7% and the wide low energy peak. The low energy peak depends strongly on details of design and is unsuitable for the study of New Physics phenomena. We find simple approximate form of spectra of colliding photons for γγ and eγ colliders,whose convolution describes high energy luminosity peak with good accuracy in the most essential preferable region of parameters.
