The cut flow on the raw generated events for the signal point (scalar top mass, scalar tau mass) = (337,148) GeV for the hadron-hadron SR. The production cross section for this signal point is $1.00 \pm 0.14$ pb. Quality Cuts indicate a set of cuts applied to ensure good quality events in data. A full description of the cuts used is given in the text. The original input file has a filter applied to it that ensures that all the events have $E_T^{miss}>60$ GeV or one electron or muon with $p_\mathrm{T} > 20$ GeV at truth level. After the filter is applied (efficiency = 0.883) there are 100000 events remaining.

The cut flow on the raw generated events for the signal point (scalar top mass, scalar tau mass) = (195,87) GeV for the lepton-hadron LM SR. The production cross section for this signal point is $21 \pm 3$ pb. Quality Cuts indicate a set of cuts applied to ensure good quality events in data. A full description of the cuts used is given in the text. The original input file has a filter applied to it that ensures that all the events have $E_T^{miss}<60$ GeV and one electron or muon with $p_\mathrm{T} > 20$ GeV at truth level.

The cut flow on the raw generated events for the signal point (scalar top mass, scalar tau mass) = (391,337) GeV for the lepton-hadron HM SR. The production cross section for this signal point is $0.41 \pm 0.06$ pb. Quality Cuts indicate a set of cuts applied to ensure good quality events in data.

The original input file has a filter applied to it that ensures that all the events have either $E_T^{miss}>150$ GeV or at least one electron or muon with $p_\mathrm{T} > 20$ GeV at truth level. After the filter is applied (efficiency = 0.925) there are 50000 events remaining before applying the event weights.

Selection acceptance times efficiency as a function of WPRIME mass at truth level for left- and right-handed WPRIME MC. The total efficiency curves correspond to the sum of the efficiencies of the one b-tag and two b-tag categories.

Cutflow (efficiency with respect to total number of events in %) for several WPRIME masses in the left-handed and in the right-handed model for hadronic top-quark decays.

Overview of the signal acceptance times efficiency (A x Eff) for the hadronic top-quark decay for both categories, the predicted cross section times branching ratio to TOP BOTTOM, as well as the observed 95% CL limit on the cross section times branching ratio for several WPRIME masses in the left-handed and in the right-handed model. The expected signal event yields in the two categories for 20.3 fb-1 of 8 TeV data are also shown.
