A search for third-generation leptoquarks in the non-resonant production with the ATLAS experiment and development of the Level-0 muon trigger for the High Luminosity LHC
No full textRecent observations performed by several high-energy physics experiments have shown anomalies in b-hadron decays, which could be explained by assuming the existence of a particle, the leptoquark, coupled both to leptons and quarks. Such measurements also suggest a preferential coupling to third-generation fermions. In this thesis, a search for third-generation leptoquarks is presented, considering the non-resonant leptoquark production. The non-resonant production is expected to yield high sensitivity from the large interference term between the Standard Model Drell-Yan process and the leptoquark t-channel exchange. The leptoquark search uses the 140 fb−1 of pp collision data collected by the ATLAS detector during the LHC Run 2 and considers di-lepton final state events, with at least one hadronically decaying tau-lepton. Deviations from the Standard Model predictions are looked for in the visible invariant mass spectrum of the di-lepton system, binned in b-jet multiplicity. In the absence of a significant deviation, exclusion limits are determined on the leptoquark coupling for different leptoquark mass values.
This thesis also presents a contribution to the upgrade of the ATLAS Muon Spectrometer in preparation for the High-Luminosity LHC. In order to cope with the much harsher conditions of the high-luminosity phase of the LHC, the entire trigger and readout electronics of the Resistive Plate Chamber detectors in the barrel region of the Muon Spectrometer will be replaced and novel FPGA-based boards will be installed. On-detector Data Collector and Transmitter boards will collect the front-end data and transmit them to off-detector Sector Logic boards, which will execute the Level-0 Muon trigger algorithm and the readout logic. In this thesis, the development of the firmwares that will be implemented in the FPGAs of the Data Collector and Transmitter boards and of the barrel Sector Logic boards is presented
Status of the Level-0 ATLAS Barrel Muon Trigger for High-Luminosity LHC
No full textThe ATLAS level-0 barrel muon trigger for High-Luminosity LHC will use data from RPC and MDT muon detectors and from the Tile Calorimeter. RPC hit data will be collected by on-detector Data Transmitter and Collector (DCT) boards and will be sent off-detector to the Sector Logic (SL) boards. Within a latency of 390 ns the SL boards should provide muon pre-candidates to the MDT trigger processor for an improved momentum measurement. This contribution presents the design of the system and results of recent tests of DCT and SL prototypes and firmware
Status of the Level-0 ATLAS barrel muon trigger for High-Luminosity LHC
No full textThe Muon Spectrometer of the ATLAS detector will be substantially modified during the Phase-II Upgrade to cope with the higher particle rates and radiation levels of the High-Luminosity LHC. The entire trigger and readout electronics of the Resistive Plates Chambers will be replaced. The Resistive Plate Chambers hit data will be collected by on-detector Data Transmitter and Collector boards and will be sent off-detector to the Sector Logic boards, which will perform the Level-0 barrel muon trigger algorithm and the readout logic. This contribution presents the design of the Phase-II barrel muon trigger and data acquisition system and the developement of the barrel Sector Logic board firmware and its challenges

»It contained harbours that pleased me like sonnets«. Kleine Poetik der diegetischen Karte
No full textIn this article, Federico Italiano explores the relationship between literature and cartography. Beginning with Stevenson’s Treasure Island, the author frames the topic through a general theoretical lens on the spatial dimension of literary texts. He then focuses on a specific phenomenon of literary "carticity"—the diegetic presence of the map, that is, the map as an integral element of the narrative structure. Among others, Italiano examines the works of Houellebecq and Cormac McCarthy

Aneddoti e ricette a corte di Federico II nel XXI secolo : il buon cibo e il buon bere nel più antico Ateneo pubblico al mondo
No full text[Italiano]: Questo volume rappresenta la finalizzazione di una iniziativa nata, condivisa ed interamente realizzata all'interno del gruppo social dei "Prof in cucina e in Cantina", che ha inteso raccogliere ricette e descrizioni aneddotiche di singoli Autori, appartenenti ai ruoli del personale docente e tecnico-amministrativo-bibliotecario dell'Ateneo federiciano, il più antico Ateneo pubblico al mondo. Aneddoti e ricette forniscono spaccati di vita quotidiana e ricostruzioni di eventi che hanno accompagnato gli Autori nei diversi percorsi formativi, sociali e lavorativi, e che non escludono riferimenti al recente periodo emergenziale della pandemia COVID-19. Ad introdurre il Volume è un menù federiciano, con una proposta di 3 pietanze che attualizzano ricette ed abitubini alimentari dell'epoca, e che hanno come riferimento il Liber de coquina, edito a corte di Federico II. Gli 8 Capitoli del volume raggruppano ricette e aneddoti per categorie, e ciascuno di essi è poi preceduto da un breve inserto con ulteriori riferimenti storici all'alimentazione a Corte di Federico II. Così, atmosfere vecchie e nuove, accompagnate dal sentore di aromi e da suggestioni ispirate al vissuto di ciascun Autore, si fondono per offrire a Lettrici e Lettori frammenti di quotidianità vissuti oggi a corte di Federico II, nel XXI secolo./[English]: The Volume represents the endpoint of a recent initiative, which was conceived, shared and fully realized within the social group of the "Prof in Cucina e in Cantina". Here, the several Authors, represented by the teaching and the technical/administrative/librarian staff of the Federico II University in Naples, the oldest public University in the world, propose recipes and anecdotal descriptions of their educational, social and work-related paths, including some episodes from the recent COVID-19 pandemic. A menu inspired to Frederick II introduces the book, with 3 recipes inspired to the Liber de coquina, a cooking manual compiled at the Emperor's court. Each of the following 8 thematic chapters of the book is also anticipated by a brief insert reporting historical reconstructions of the alimentary habits at the court of Frederick II. Thus, old and new atmospheres, accompanied by the scent of aromas and suggestions inspired by the experience of each Author, come together to offer Readers fragments of everyday life at the court of Frederick II, in the 21st century
Federico De Roberto, «L’imperio»
No full textIl breve saggio analizza l'incipit dell'Imperio di Federico De Roberto mettendo a fuoco come l'Autore riesca a dare una rappresentazione teatrale del parlamento e, con ciò, a desacralizzarne la funzione politica e a ridicolizzarne i principali attori: i parlamentari. Questo incipit è ovviamente funzionale alla successiva narrazione della progressiva delusione politica di Ranaldi.The short essay examines the incipit of "L'imperio" by Federico De Roberto focusing on how the author manages to give a theatrical performance of the parliament and, thereby, to desecration and ridiculing the political function of the main actors: the parliamentarians. This incipit is obviously functional to the narration of the progressive political disappointment of Ranaldi
