====== Single Top plus dark matter at LHC ====== People: Genevieve Belanger, Jose No, Priscilla Pani, Giacomo Polesello, Bryan Zaldivar, Fabio Maltoni Email: , , , , , , ==== 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 ==== References ====
