Homer and the Poetics of Hades

In this thesis I examine Homer’s use of Hades as a poetic resource that allows a different approach to the epic past than the one provided through Muse-inspired narrative. By portraying Hades as a realm where vision is not possible (A - ides), I argue, Homer creates a unique poetic environment in which social constraints and divine prohibitions are not applicable. The result is a narrative that emulates that of the Muses but at the same time is markedly distinct from it, as in Hades experimentation with, and alteration of, important epic forms and values can be pursued, giving rise to a different kind of poetics. I have called this the ‘Poetics of Hades.’ In the Iliad, Homer offers us a glimpse of how this alternative poetics works through the visit of Patroclus’ shade in Achilles’ dream. The recollection offered by the shade reveals an approach to its past in which regret, self-pity and a lingering memory of intimate and emotional moments displace an objective tone, and a traditional exposition of heroic values such as kleos and timē. I argue that the potential of Hades for providing alternative means of commemorating the past is more fully explored in the ‘Nekyia’ of Odyssey 11; there, Odysseus’ extraordinary ability to see (idein) the dead in Hades allows him to meet and interview the shades of heroines and heroes of the epic past. The absolute confinement of Hades allows the shades to recount their stories from their own personal point of view. The poetic implications of this, I argue, are important since by visiting Hades and listening to the stories of the shades Odysseus, and Homer with him, gain access to a tradition in which epic values associated with gender roles and even divine law are suspended, in favour of a more immediate and personally inflected approach to the epic past

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
