Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes in detail the search for new phenomena in mono-jet final states with the ATLAS experiment at the LHC. The final state is considered the golden channel in the searches for large extra dimensions (LED) but also allows access to a very rich SUSY-related phenomenology pertaining to the production of weakly interacting massive particles (WIMPS), SUSY Dark Matter candidates, GMSB SUSY models with very light gravitino masses, as well as stop an sbottom pair production in compressed scenarios (with nearly degenerated squarks and the lightest neutralino), and also invisible Higgs searches, among others. Here, a number of these scenarios are explored. The measurements presented yield new powerful constraints on the existence of extra spatial dimensions, the pair production of WIMPs, and also provide the best limit to date on the gravitino mass.

Download or read book Searches for Supersymmetric Particles in Final States with Multiple Top and Bottom Quarks with the Atlas Detector written by Chiara Rizzi and published by Springer Nature. This book was released on 2020-09-01 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD thesis documents two of the highest-profile searches for supersymmetry performed at the ATLAS experiment using up to 80/fb of proton-proton collision data at a center-of-mass energy of 13 TeV delivered by the Large Hadron Collider (LHC) during its Run 2 (2015-2018). The signals of interest feature a high multiplicity of jets originating from the hadronisation of b-quarks and large missing transverse momentum, which constitutes one of the most promising final state signatures for discovery of new phenomena at the LHC. The first search is focused on the strong production of a pair of gluinos, with each gluino decaying into a neutralino and a top-antitop-quark pair or a bottom-antibottom-quark pair. The second search targets the pair production of higgsinos, with each higgsino decaying into a gravitino and a Higgs boson, which in turn is required to decay into a bottom-antibottom-quark pair. Both searches employ state-of-the-art experimental techniques and analysis strategies at the LHC, resulting in some of the most restrictive bounds available to date on the masses of the gluino,neutralino, and higgsino in the context of the models explored.

Download or read book Search for New Heavy Charged Bosons and Measurement of High Mass Drell Yan Production in Proton Proton Collisions written by Markus Zinser and published by Springer. This book was released on 2018-09-25 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents two analyses, the first of which involves the search for a new heavy charged gauge boson, a so-called W' boson. This new gauge boson is predicted by some theories extending the Standard Model gauge group to solve some of its conceptual problems. Decays of the W' boson in final states with a lepton (l± = e± , μ±) and the corresponding (anti-)neutrino are considered. Data collected by the ATLAS experiment in 2015 at a center of mass energy of √s =13 TeV is used for the analysis. In turn, the second analysis presents a measurement of the double-differential cross section of the process pp->Z/gamma^* + X -> l^+l^- + X, including a gamma gamma induced contribution, at a center of mass energy of sqrt{s} = 8 TeV. The measurement is performed in an invariant mass region of 116 GeV to 1500 GeV as a function of invariant mass and absolute rapidity of the l^+l^-- pair, and as a function of invariant mass and pseudorapidity separation of the l^+l^-- pair. The data analyzed was recorded by the ATLAS experiment in 2012 and corresponds to an integrated luminosity of 20.3/fb. It is expected that the measured cross sections are sensitive to the PDFs at very high values of the Bjorken-x scaling variable, and to the photon structure of the proton.

Download or read book Search for New Physics in tt Final States with Additional Heavy Flavor Jets with the ATLAS Detector written by Javier Montejo Berlingen and published by Springer. This book was released on 2018-05-30 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This doctoral thesis focuses on the search for new phenomena in top-antitop quark (tt) final states with additional b-quark jets at the LHC. It uses the full Run 1 dataset collected by the ATLAS experiment in proton-proton collisions at √s=8 TeV. The final state of interest consists of an isolated lepton, a neutrino and at least six jets with at least four b-tagged jets, a challenging experimental signature owing to the large background from tt+heavy-flavor production. This final state is characteristic of ttH production, with the Higgs boson decaying into bb, a process that allows direct probing of the top-Higgs Yukawa coupling. This signature is also present in many extensions of the Standard Model that have been proposed as solutions to the hierarchy problem, such as supersymmetry or composite Higgs models, which predict the pair production of bosonic or fermionic top quark partners, or the anomalous production of four-top-quark events. All these physics processes have been searched for using an ambitious search strategy that has been developed on the basis of a combination of state-of-art theoretical predictions and a sophisticated statistical analysis to constrain in-situ the large background uncertainties. As a result, the most restrictive bounds to date on the above physics processes have been obtained.

Download or read book The CBM Physics Book written by Bengt Friman and published by Springer Science & Business Media. This book was released on 2011-03-10 with total page 973 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exhaustive survey is the result of a four year effort by many leading researchers in the field to produce both a readable introduction and a yardstick for the many upcoming experiments using heavy ion collisions to examine the properties of nuclear matter. The books falls naturally into five large parts, first examining the bulk properties of strongly interacting matter, including its equation of state and phase structure. Part II discusses elementary hadronic excitations of nuclear matter, Part III addresses the concepts and models regarding the space-time dynamics of nuclear collision experiments, Part IV collects the observables from past and current high-energy heavy-ion facilities in the context of the theoretical predictions specific to compressed baryonic matter. Part V finally gives a brief description of the experimental concepts. The book explicitly addresses everyone working or planning to enter the field of high-energy nuclear physics.

Download or read book Entrepreneurial Borrowing written by Stuart Fraser and published by . This book was released on 2019-12-11 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Entrepreneurial Borrowing: Do Entrepreneurs Seek and Receive Enough Credit? reviews the extant literature on entrepreneurial borrowing and provides insights into some of the key concepts and findings in the literature. The term 'entrepreneurial borrowing' is used as shorthand for 'borrowing by Small and Medium Sized Enterprises (SMEs)'. The emphasis on the term 'borrowing' as opposed to 'lending' indicates there is a particular interest in exploring issues related to the demand for credit. In this respect, issues of entrepreneurial cognition and cognitive biases, along with related insights from the behavioral finance literature, receive due attention insofar as they may affect entrepreneurs' borrowing decisions. Finally, one cannot review this literature without examining the other (supply) side of the equation (that is, 'banks' and 'lending' to SMEs).

Download or read book Muslims of Central Asia written by Galina M. Yemelianova and published by New Edinburgh Islamic Surveys. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first history-based integrated overview of Islam and Muslims in present-day Central Asia Between the tenth and sixteenth centuries Central Asia was one of the most prestigious cultural areas of the entire Muslim world, playing a pivotal role in the Silk Road trade. Throughout that history, and up to the present, Tajiks, Uzbeks, Kazakhs, Kyrgyz, Turkmen and other Muslim peoples of Central Asia have developed their own unique understanding and practice of Islam which has shaped their national identity and particular social and political evolution. These special characteristics of Central Asian Islam ensured its survival during seventy years of Soviet atheist rule, while in the post-Soviet period Islam has been integrated into nation-building projects in constitutionally secular Uzbekistan, Kazakhstan, Tajikistan, Kyrgyzstan and Turkmenistan. This absorbing history is traced in this fascinating study which shows how, from the seventh century to the present day, the region's people have negotiated their distinctively Central Asian Islamic identity in the face of enduring external Islamic and non-Islamic dominations, ethnic nationalisms and, more recently, global transnational Islamic influences. Key Features - The first integrated account of the Muslims of the present-day states of Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan - Synthesises up-to-date research with existing Western, Russian and Central Asian scholarship on Islam and Muslims in Central Asia - Employs a Central Asia-centric approach focusing on the region as a geographically and culturally self-sustained entity, with strong links to Russia, the Middle East, South Asia, Iran, Turkey and China - Includes numerous photographs taken during field-work in Uzbekistan, Tajikistan, Kazakhstan and Kyrgyzstan Galina M. Yemelianova has researched and taught for over thirty years on various aspects of Middle Eastern and Eurasian history and contemporary Muslim politics. Among her books are Russia and Islam: A Historical Survey (2002), Islam in post-Soviet Russia (2003) and Radical Islam in the former Soviet Union (2010).
