Identifying Anomalies in Industrial Networks: A Proposed Testbed for Experimental Evaluation

Not only because of the convergence of InformationTechnology (IT) and Operational Technology (OT) networks, thepass-through network environment needs to be monitored andadequate security implemented. Due to the occurrence of differenttypes of anomalies and their inconsistency in the literature,three main types of anomalies have been identified in this paperand a testbed has been proposed to serve for further experimentaltesting. This testbed was created using an anemometer and inthe current state using an accelerometer. From the results sofar, a correlation between the normal condition and the inducedoperational anomaly can be observed

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
