This book discusses searches for Dark Matter at the CERN’s LHC, the world’s most powerful accelerator. It introduces the relevant theoretical framework and includes an in-depth discussion of the Effective Field Theory approach to Dark Matter production and its validity, as well as an overview of the formalism of Simplified Dark Matter models. Despite overwhelming astrophysical evidence for Dark Matter and numerous experimental efforts to detect it, the nature of Dark Matter still remains a mystery and has become one of the hottest research topics in fundamental physics. Two searches for Dark Matter are presented, performed on data collected with the ATLAS experiment. They analyze missing-energy final states with a jet or with top quarks. The analyses are explained in detail, and the outcomes and their interpretations are discussed, also in view of the precedent analysis of theoretical approaches. Given its depth of coverage, the book represents an excellent reference guide for all physicists interested in understanding the theoretical and experimental considerations relevant to Dark Matter searches at the LHC.
Incorporating more than one linguistic code or mode of expression in literary and artistic productions has quickly grown over the last two decades. This volume pays special attention to the dynamic rise of code-switching especially in literature and performative arts, and explores strategies used by contemporary artists to compose their multilingual narratives as well as moves beyond the linguistic level in the direction of multimodality. The innovative frameworks and descriptions intend to highlight the different ways in which art, unlike ordinary language use, manifests language mixing and switching. Besides the papers by both young and established scholars, the volume includes a section of valuable contributions from multilingual authors and artists to bridge the gap between academic approaches and creative professional practices.
