The LHC Phenomenology of the CP-odd Scalar in Two-Doublet Models

Abstract

We discuss possible signatures of the $CP$-odd scalar of two-doublet models at the LHC. We find that the inclusive two-photon decay mode and the decay sequence $A^0\to Zh,h\to \gamma \gamma$, where $h$ is a $CP$-even neutral scalar, can give viable signals in fairly large and complementary regions of parameter space.
