Title: Are there hidden scalars in the LHC results?

Abstract: In the Two Higgs Doublet Model, scalars heavier than the 125 GeV state recently discovered at the LHC are predicted. Those heavier particles - a charged scalar H^+, a pseudoscalar A and a heavier CP-even state H - can decay to to lighter scalar h, and for considerable regions of parameter space, those decays have branching ratios close to unity. Their production cross-sections at the LHC can be quite large as well, and as such there is the possibility that part of the scalars we are currently seeing at the LHC are the result of the decay of the heavier states. In that sense, we may already, unknowingly, be observing extra scalars at the LHC. We will show that this mechanism of chain Higgs production can amount to as much as 20% of the number of scalars produced at the LHC.
