The process is computed using all the possible diagrams at the next-to-leading order, including box, triangle, and self-energy diagrams. The numerical analysis is carried out for the production rates of the lightest chargino pair in RNS, NS, mSUGRA, BB, and NUGM scenarios. These distinct benchmark models were introduced in the light of the LHC results presented at root s = 7-8 TeV. Among these scenarios, the RNS has the highest production rate for the gamma gamma -> (chi) over tilde (+)(1)(chi) over tilde (-)(1). The partonic cross section reaches up to 3.94 pb at root(s) over cap =310 GeV. The total convoluted cross section with the photon luminosity in a e(+)e(-) machine is calculated as a function of the center-of-mass energy up to 1 TeV. The convoluted cross section is similar to 1.05 pb at root(s) over cap= 350 GeV depending on the polarization of the initial electron and laser polarization. The RNS along with the BB scenarios are accessible at root(s) over cap = 500 GeV with a gamma gamma collision mode on e(+) e(-)-collider. (C) 2018 The Author(s).
