Book Synopsis A Search for Displaced Leptons in the ATLAS Detector by : Lesya Horyn
Download or read book A Search for Displaced Leptons in the ATLAS Detector written by Lesya Horyn and published by Springer Nature. This book was released on 2022-02-07 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a search for long-lived particles decaying into displaced electrons and/or muons with large impact parameters. This signature provides unique sensitivity to the production of theoretical lepton-partners, sleptons. These particles are a feature of supersymmetric theories, which seek to address unanswered questions in nature. The signature searched for in this thesis is difficult to identify, and in fact, this is the first time it has been probed at the Large Hadron Collider (LHC). It covers a long-standing gap in coverage of possible new physics signatures. This thesis describes the special reconstruction and identification algorithms used to select leptons with large impact parameters and the details of the background estimation. The results are consistent with background, so limits on slepton masses and lifetimes in this model are calculated at 95% CL, drastically improving on the previous best limits from the Large Electron Positron Collider (LEP).

Book Synopsis The Road to Discovery by : John Alison
Download or read book The Road to Discovery written by John Alison and published by Springer. This book was released on 2014-09-11 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented here includes important contributions on the commissioning of the ATLAS experiment and the discovery of the Higgs boson. The thesis describes essential work on the alignment of the inner tracker during the commissioning of the experiment and development of the electron identification algorithm. The subsequent analysis focuses on the search for the Higgs boson in the WW channel, including the development of a method to model the critical W+jet background. In addition, the thesis provides excellent introductions, suitable for non-specialists, to Higgs physics, to the LHC, and to the ATLAS experiment.

Available in PDF, EPUB and Kindle. Book excerpt: This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments. It also covers applications in medicine and life sciences. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
Book Synopsis Probing Lepton Flavour Violation Via Neutrinoless [tau]2![mu] Decays with the ATLAS Detector by :
Download or read book Probing Lepton Flavour Violation Via Neutrinoless [tau]2![mu] Decays with the ATLAS Detector written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This article presents the sensitivity of the ATLAS experiment to the lepton-flavour-violating decays of [tau]2![mu]. A method utilising the production of [tau] leptons via W2!tau][nu] decays is used. This method is applied to the sample of 20.3 fb-1 of pp collision data at a centre-of-mass energy of 8 TeV collected by the ATLAS experiment at the LHC in 2012. Lastly, no event is observed passing the selection criteria, and the observed (expected) upper limit on the [tau] lepton branching fraction into three muons, Br([tau]2![mu]), is 3.76×10-7 (3.94×10-7) at 90 % confidence level.

Book Synopsis Identifying Hadronic Tau Decays Using Calorimeter Topological Clusters at ATLAS by : Michel Trottier-McDonald
Download or read book Identifying Hadronic Tau Decays Using Calorimeter Topological Clusters at ATLAS written by Michel Trottier-McDonald and published by . This book was released on 2010 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ATLAS experiment collects data on the world's highest energy proton-proton collisions. Its primary goals are to search for direct evidence of physics beyond the Standard Model of particle physics, and to provide a final verdict on the existence of the Standard Model Higgs boson. A robust tau identification procedure is an important ingredient in the search for Standard Model and supersymmetric Higgs bosons. In this study, new tau identification variables based on calorimeter topological clusters are investigated. These variables complement existing calorimeter-based variables by bringing additional discriminating power against hadronic jets. They have a straightforward physics interpretation which allows them to be calculated at particle-level. Some of these new variables are shown to be robust against background noise from the underlying event and in-time pileup, two effects which negatively impact tau identification. Several of these new variables are now part of the official tau reconstruction software at ATLAS.
Book Synopsis Tau Trigger at the ATLAS Experiment by :
Download or read book Tau Trigger at the ATLAS Experiment written by and published by . This book was released on 2011 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many theoretical models, like the Standard Model or SUSY at large tan([beta]), predict Higgs bosons or new particles which decay more abundantly to final states including tau leptons than to other leptons. At the energy scale of the LHC, the identification of tau leptons, in particular in the hadronic decay mode, will be a challenging task due to an overwhelming QCD background which gives rise to jets of particles that can be hard to distinguish from hadronic tau decays. Equipped with excellent tracking and calorimetry, the ATLAS experiment has developed tau identification tools capable of working at the trigger level. This contribution presents tau trigger algorithms which exploit the main features of hadronic tau decays and describes the current tau trigger commissioning activities. Many of the SM processes being investigated at ATLAS, as well as numerous BSM searches, contain tau leptons in their final states. Being able to trigger effectively on the tau leptons in these events will contribute to the success of the ATLAS experiment. The tau trigger algorithms and monitoring infrastructure are ready for the first data, and are being tested with the data collected with cosmic muons. The development of efficiency measurements methods using QCD and Z → [tau][tau] events is well advanced.
