SUSY Search in TeV Scale Polarized Photon-Proton Collisions Z.Z.Aydin, A. Kandemir, O.Yılmaz and A.U. Yılmazer Ankara University, Faculty of Sciences Department of Engineering Physics 06100 Tando˘gan, Ankara - Turkey Production of supersymmetric particles in TeV scale polarized photon-proton collisions is dis- cussed. Polarizations of both photon and proton beams are considered. Associated productions of squark-chargino and squark-gluino, and production of squark pairs have been examined. Although the cross sections for different initial beam polarizations do not differ much, the polarization asym- metry is sensitive to the sparticle mass. We conclude that the capacity of future linac-ring type TeV scale photon-proton colliders is quite promising in the search for SUSY particles. 0 0 0 2 I. INTRODUCTION n u J In recent years in addition to the well known TeV scale colliders such as pp (pp¯), ep and e+e− machines the possibil- 7 ities of the realization of γe, γγ and γp colliders have been proposed and discussed in detail [1]. Here one of the main 2 motivations is to reach the TeV scale at a subprocess level. The collisions of protons from a large hadron machine with electrons from a linac is the most efficient way of achieving TeV scale at a constituent level in ep collisions [2]. 1 A further interesting feature is the possibility of constructing γp colliders on the base of linac-ring ep-machines. This v can be realized by using the
