We present the matrix element of γγ → 4l process with four charge particles in final state. The constructions are performed in frame of Standard Model of electroweak interaction using the helicity amplitude method. Every possible polarization state of initial and final particles are considered and analyzed.

The black hole singularity plays a crucial role in formulating Hawking's information paradox. global spacetime analysis may be reconciled with unitarity by imposing final state boundary condition on the spacelike singularity. Motivated proposal, we explore effect of projection two dimensional conformal field theories. We calculate time evolution under postselection employing real part pseudoent...
