==== Idea ====
  * Understand the power of single top/Wt signatures in the context of Dm simplified models and 2HDM

==== Setup ====
  * Model currently in use is the 2HDM + pseudoscalar from Ref []
  * Additional posible models: singlet (available), double singlet (not available)

==== Detailed Work Plan ====

1) H+t on shell
  * check xsec*BR for H+top (Giacomo)
  * check multijet susy recast sensitivity (Benji+inputs Giacomo)

2) H+H- (Jose)
  * check the cross section and compare with chargino production
  * recast the chargino analysis in WW

3) check diphoton constraints on the A/H guys for low tan beta  (Brian)

==== General Work Plan ====

  * Establish viable regions of parameter space of 2HDM+S model via scan of parameter space

  * Evaluate sensitivity of existing monotop searches in parameter space

  * Develop dedicated search strategy based on parametrised simulation of signal and background and evaluate reach for 300 fb-1 (Benj: why would a different monotop strategy be needed? Giacomo Because existing analyses may cut too hard for the topologies we are interested in; Benj: aha this is the thing we discussed the other day! Then I am definitely interested.)

  * Compare final state topology with simplified model with only one singlet

  * Develop variables for measurement of model characteristics
