Search for new physics with same-sign isolated dilepton events with jets and missing energy

Abstract

The results of a search for new physics in events with two same-sign isolated leptons (electrons, muons, or hadronically decaying tau-leptons), hadronic jets, and missing transverse energy in the final state are presented. These results are based on analysis of a data sample with a corresponding integrated luminosity of 0.98 fb−1 produced in pp collisions at a center-of-mass energy of 7 TeV collected by the CMS experiment at the LHC. The observed numbers of events agree with the standard model predic- tions, and no evidence for new physics is found. These observations are used to set upper limits on the number of events from new physics contributions and to constrain supersymmetric models.

The net predicted yields, differing in estimates of the fake lepton contributions using methods (A1), (A2), and (B), are shown separately. The uncertainties include the statistical and systematic components added in quadrature

The net predicted yields, differing in estimates of the fake lepton contributions using methods (A1), and (B), are shown separately. The uncertainties include the statistical and systematic components added in quadrature. The last column (95% CL UL yield) represents observed upper limits on event yields from new physics

Table7.png Table 7: A summary of the expected simulated background events and events with charge misreconstruction. The contributions to the simulated backgrounds are displayed by process: WZ/ZZ/ttbarW, same-sign W-boson production in double-parton-pari scattering, double "W-strahlung" with same-sign W bosons and W/Z production in association with a photon.
Table8.png Table 8: Comparison of observed 95% CL upper limits computed with different statistical methods. Results are displayed for a limit set using Bayesian, and hybrid frequentist-Bayesian CLs method. For the CLs technique, two results are reported: one obtained using the ratio of the signal-with-background and background-only likelihoods with central values of the nuisance parameters (LEP CLs ) and the other obtained with parameters, including the signal strength, maximizing the ratio (LHC CLs ). The main values for upper limits in this analysis are reported using the LHC CLs method. Log-normal distributions for the nuisance parameters and a uniform signal strength are used in all methods.

Re-interpretation in terms of simplified models

The language of simplified models has been introduced recently (see e.g. here and here) to establish an efficient communication channel between the LHC experiments and the theory communities who have proposed a general set of simplified models with which LHC data can be interpreted. A similar approach has been taken before in the hadronic channel with 2010 data -- see here.

The above results have been re-interpreted in terms of the simplified models given in the following table.

The signal efficiencies as a function of the mass parameters of the simplified model are also given below, together with upper limit plots on the production cross section. The data for these plots are also available as a ROOT file: T1lnu_SS.root. The regions with 
small 
ΔΜ(gluino,LSP)
 are 
excluded since they are
 dominated by 
statistical 
errors 
and
 signal 
modeling uncertainty. Signal contamination in control regions has not been taken into account when computing the upper limits on the production cross sections.
