ENGAGEMENT MATTERS: An exploration of public engagement and its futures in Toronto

As public engagement gains momentum as a mechanism for engaging residents in a changing political climate, its effectiveness is more important than ever. This study, divided into three volumes, explores matters related to public engagement for city-building decisions. Volume 1 is a primer on public engagement, meant to support municipal public servants to understand the basics of public engagement. This Volume is informed by user and expert interviews, ethnographic observation, and system mapping tools conducted during the first phase of this research. Volume 2 builds on insights developed during the first phase of this research, to explore the futures of public engagement in 2033 using strategic foresight. Written for public servants familiar with the field of public engagement, Volume 2 is an exploration of key trends impacting the futures of public engagement and possible future scenarios. These scenarios were developed using a collective scenario process, which Volume 3 describes in detail, in the hopes that foresight and public engagement practitioners might find use in iterating and utilizing this process to explore participatory future-focused conversations

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
