“…[44] that results for slepton searches in simplified models could safely be applied to the production of fermion pairs decaying into a fermion and a scalar. We use SmodelS [45], a tool designed to decompose the signal of any NP model into simplified topologies, and compare the predictions to the exclusion limits set by the ATLAS and CMS slepton searches [46,47]. We find that the 8 TeV LHC sets strong constraints on the mass of L − , even stronger than for smuons, because L + L − pair production cross sections are significantly larger.…”

We show that the recently reported anomalies in b → sµ + µ − transitions, as well as the longstanding gµ − 2 discrepancy, can be addressed simultaneously by a new massive abelian gauge boson with loop-induced coupling to muons. Such a scenario typically leads to a stable dark matter candidate with a thermal relic density close to the observed value. Dark matter in our model couples dominantly to leptons, hence signals in direct detection experiments lie well below the current sensitivity. The LHC, in combination with indirect detection searches, can test this scenario through distinctive signatures with muon pairs and missing energy.

“…This is achieved through decomposition of the signal into simplified models, as is done by the programs SModelS [364] and FastLim [365]. This approach will be used to constrain, using SModelS, two specific scenarios of supersymmetric dark matter in Sections 3.2 and 3.3.…”

“…There are other recasting tools on the market, as SModelS [26,27] and Fastlim [28]. These tools are similar in concept to XQCAT, but they are dedicated to testing SUSY scenarios, and therefore they are complementary to XQCAT in terms of the new physics scenarios they are able to constrain.…”

XQCAT (eXtra Quark Combined Analysis Tool) is a tool aimed at determining exclusion confidence levels for scenarios of new physics characterised by the presence of one or multiple heavy extra quarks which interact through Yukawa couplings with any of the Standard Model quarks. The code uses a database of efficiencies for pre-simulated processes of QCD-induced pair production of extra quarks and their subsequent on-shell decays. In the version 1.2 of XQCAT the efficiencies have been computed for a set of seven publicly available search results by the CMS experiment. The input for the code is a text file in which masses, branching ratios and dominant chirality of the couplings of the new quarks are provided. The output of the code is the exclusion confidence levels of the test point for each implemented experimental analysis considered individually and, when possible, in statistical combination. the Standard Model (SM) with only one XQ representation which couples only to the third generation SM quarks or only to the SM light quark families. In contrast, various theoretically-motivated scenarios of new physics predict a new quark sector, i.e. more than one new quark, with general couplings to SM quarks. Notable examples are composite Higgs models or universal extra-dimensions. Hence, recasting experimental limits for these scenarios can be a challenging task. To avoid time-consuming simulations and dedicated searches for scenarios which can already be excluded by current data, we present a tool for reinterpretation of existing experimental analyses, including those not made for XQs searches, in terms of exclusion confidence levels (eCLs) for XQ models. Our tool should serve as a useful preliminary approach to understand in a quick way the regions of validity of scenarios of new physics. Solution method: The core of the tool consists in a database of pre-simulated efficiencies (ǫ), defined as the ratio of signal events which survive a given set of experimental cuts over the total number of signal events. These efficiencies have been computed simulating the process of pair production and decay of XQs with masses in the range 400-2000 GeV and implementing the selection and kinematics cuts of a set of experimental searches at 7 and 8 TeV. The tool uses the database to reconstruct any scenario where XQs couple to SM quarks through Yukawa interactions and gives as output the eCL of the test point, characterised by values of the XQ masses and their branching ratios (BRs) into specific final Keywords Preprint submitted to Computer Physics CommunicationsSeptember 18, 2015 states, for all the implemented searches. It also provides eCLs for combinations of experimental searches when search bins are uncorrelated. The method has been validated against experimental analyses. Restrictions:The efficiency database has been built under the following hypotheses: QCD-induced pair production of quarks with masses from 400 GeV to 2000 GeV with steps of 100 GeV; the electro-weak ( [7]. The code also relies on the possibility ...
