Search for large missing transverse momentum in association with one top-quark in proton-proton collisions at s√=13 TeV with the ATLAS detector

This paper describes a search for events with one top-quark and large missing transverse momentum in the final state. Data collected during 2015 and 2016 by the ATLAS experiment from 13 TeV proton–proton collisions at the LHC corresponding to an integrated luminosity of 36.1 fb−1 are used. Two channels are considered, depending on the leptonic or the hadronic decays of the W boson from the top quark. The obtained results are interpreted in the context of simplified models for dark-matter production and for the single production of a vector-like T quark. In the absence of significant deviations from the Standard Model background expectation, 95% confidence-level upper limits on the corresponding production cross-sections are obtained and these limits are translated into constraints on the parameter space of the models considered

Seeing Where Others See Nothing: Coetzee's Magda, Cassandra in the Karoo

Zinato approaches Magda, the Afrikaner protagonist of J.M. Coetzee\u2019s In the Heart of the Country (1977) as a Cassandra figure. Focusing on audible echoes from Aeschylus\u2019 Agamemnon and Euripides\u2019 Trojan Women she draws attention to the text\u2019s perceivable allusions to the tragic, wildly defiant seer possessed by Apollo and condemned by him never to be believed. Far from being tempted by any exotic antiquarianism, and far from bluntly assimilating Coetzee\u2019s novel to the Greek paradigm, the critic\u2019s evocation of Cassandra entails evoking engaging and compelling ways in which Attic tragedy may shed renewed light on Magda\u2019s alleged madness, on her text\u2019s discouraging a discourse of individual psychology, and, finally, on the essentially tragic features of Coetzee\u2019s text as a whole
