Two Photon Processes and Effective Lagrangians with An Extended Scalar Sector

Abstract

We consider the Standard Model with an extended scalar sector, and study the possible effects of the physics underlying such a model using an effective lagrangian parametrization. It is found that certain two photon processes offer windows where such heavy interactions might be glimpsed, but the realization of this expectation requires enormous experimental precision.
