Responsible: Ken Lane Participants: Ken & Jon B + Will Shepherd + David Sperka Notes on Parameters KL: The definition of $\sin(\beta-\alpha)$ is inverted in this file compared to usual convention of Branco et al., so the alignment limit is achieved when $\sin(\beta-\alpha) = 0$ (It is $\sin(\beta-\alpha) = 1$ in the standard definition of Branco et al. because they define the $\rho_1,\rho_2 \rightarrow h,H (= h1,h2$$\alpha$$\pi/2$$\alpha = \beta$$h1 = H(125)$$\sin(\beta - \alpha) = \sin\delt…

Responsible: Jose Zurita Idea: simplified models for the hh + MET signature (with hh->4b) were put forward in this paper . Possible projects include studying other final states (e.g: bb + tau tau + MET, bbWW+MET, etc) and also embedding the simplified models in a larger picture including constraints coming from relic density, direct detection and indirect detection.

The starting point is the review/compendium work on exotic Higgs decays from Curtin, Gori, Shelton, Strassler... 1312.4992, which delineates a programme to cover as many exotic decays of the 125 GeV Higgs (and provide motivation!) as possible. While the list of possible decays in the review is quite exhaustive, several of these decays have not been studied in detail. Two such cases ar…
