Описание: In this work, the interaction between the Higgs boson and the top quark is studied with the proton-proton collisions at 13 TeV provided by the LHC at the CMS detector at CERN (Geneva). At the LHC, these particles are produced simultaneously via the associate production of the Higgs boson with one top quark (tH process) or two top quarks (ttH process). Compared to many other possible outcomes of the proton-proton interactions, these processes are very rare, as the top quark and the Higgs boson are the heaviest elementary particles known. Hence, identifying them constitutes a significant experimental challenge. A high particle selection efficiency in the CMS detector is therefore crucial. At the core of this selection stands the Level-1 (L1) trigger system, a system that filters collision events to retain only those with potential interest for physics analysis. The selection of hadronically decaying ? leptons, expected from the Higgs boson decays, is especially demanding due to the large background arising from the QCD interactions. The first part of this thesis presents the optimization of the L1 ? algorithm in Run 2 (2016-2018) and Run 3 (2022-2024) of the LHC. It includes the development of a novel trigger concept for the High-Luminosity LHC, foreseen to start in 2027 and to deliver 5 times the current instantaneous luminosity. To this end, sophisticated algorithms based on machine learning approaches are used, facilitated by the increasingly modern technology and powerful computation of the trigger system. The second part of the work presents the search of the tH and ttH processes with the subsequent decays of the Higgs boson to pairs of ? lepton, W bosons or Z bosons, making use of the data recorded during Run 2. The presence of multiple particles in the final state, along with the low cross section of the processes, makes the search an ideal use case for multivariant discriminants that enhance the selectivity of the signals and reject the overwhelming background contributions. The discriminants presented are built using state-of-the-art machine learning techniques, able to capture the correlations amongst the processes involved, as well as the so-called Matrix Element Method (MEM), which combines the theoretical description of the processes with the detector resolution effects. The level of sophistication of the methods used, along with the unprecedented amount of collision data analyzed, result in the most stringent measurements of the tH and ttH cross sections up to date.

Описание:
«A brilliant, touching and thought-provoking book. Moving Along merges academic research with personal narrative and beautifully rendered drawings to create a one-of-a-kind book that contributes fresh and compelling perspectives. This life-affirming graphic novel is essential reading for anyone interested in Parkinson’s and the power of art and community to sustain and nurture the human spirit.»
(David Leventhal, Program Director and Founding Teacher, Dance for PD®, Mark Morris Dance Group, Brooklyn, NY USA)
«This is a wonderfully accessible book that has been co-created by people living with Parkinson’s, researchers and artists. In the true-to-life stories, the anxieties and challenges of living with Parkinson’s are explored in evocative cartoons. Yet , as well as talking about the challenges, the book has the joy of dancing at its heart. Dance has proved to be an exceptionally good catalyst for living well with Parkinson’s and this graphic novel illustrates individual journeys through Parkinson’s and into dance. For anyone curious about dancing who now lives with Parkinson’s, or knows someone who does, this book is for you. For anyone interested in graphic medicine, dance for wellbeing, or arts in healthcare, this book is an important addition to the literature. »
(Professor Sara Houston, author of Dancing with Parkinson’s)
Meet Hugo, Karen, Alma, Helene, Anne-Marie, Poul, Lone, and Eskild, who go to Parkinson’s dance class together. They are characters in this graphic novel, which is based on many stories about Parkinson’s. The stories come from participants in Parkinson’s dance who have talked about how dance involves bodily, aesthetic experiences, including the feeling of bubbles in their bodies and flying together. Dancing brings joy, energy, and community, and thereby strengthens the will to live, all important when a chronic illness turns your world upside down.
This book, a co-produced research-based graphic novel, is designed for use in the fields of arts and health, medical humanities, graphic medicine, and narrative medicine. It is also written for people with Parkinson’s, or other chronic diseases, and their families. The book invites dialogue about the existential dimensions of chronic illness, especially Parkinson’s, and long-term caregiving.

Описание: Produced water is mainly salty water trapped in the reservoir rock and brought up along with oil or gas during production. Suitable for those who are involved in the design, operation, maintenance and sizing of produced water treatment systems, this book deals with the technology, management, treatment, and handling practices.
Описание: Bluegrass Ambassadors is the first book-length study of the McLain Family Band, which has spread the gospel of bluegrass for more than fifty years. Rooted in bluegrass but also collaborating with classical composers and performing folk, jazz, gospel, and even marches, the band traveled to sixty-two foreign countries in the 1970s under the auspices of the State Department. The band's verve and joyful approach to its art perfectly suited its ambassadorial role. After retiring as full-time performers, most members of the group became educators, with patriarch Raymond K. McLain's work at Berea College playing a particularly important role in bringing bluegrass to the higher education curriculum.Interpreting the band's diverse repertoire as both a source of its popularity and a reason for its exclusion from the bluegrass pantheon, Paul Jenkins advances subtle arguments about genre, criticism, and audience. Bluegrass Ambassadors analyzes the McLains' compositions, recordings, and performances, and features a complete discography.

Описание:
The world of laser matter interaction has known great and rapid advancements in the last few years, with a considerable increase in the number of both experimental and theoretical studies. The classical paradigm used to describe the dynamics of laser produced plasmas has been challenged by new peculiar phenomena observed experimentally, like plasma particles' oscillations, plume splitting and self-structuring behavior during the expansion of the ejected particles. The use of multiple complementary techniques has become a requirement nowadays, as different aspects can be showcased by specific experimental approaches. To balance these non-linear effects and still remain tributary to the classical theoretical, views on laser produced plasma dynamics novel theoretical models that cover the two sides of the ablation plasma (differentiability and non-differentiability) still need to be developed. Plasma is a strongly nonlinear dynamic system, with many degrees of freedom and other symmetries, favorable for the development of ordered structures, instabilities and transitions (from ordered to chaotic states). In such contexts, we showcased research based on global and local symmetries, complexity and invariance. This special number highlighted exciting new phenomena related to laser produced plasma dynamics with the implementation of theoretical models, towards understanding the complex reality of laser matter interaction.
