We compute the total cross-section for direct production of the pseudoscalar Higgs boson in hadron collisions at next-to-next-to-leading order (NNLO) in perturbative QCD. The[Omicron]([alpha][sub s][sup 2]) QCD corrections increase the NLO production cross-section by approximately 20-30%.

We compute the total cross-section for direct Higgs boson production in hadron collisions at NNLO in perturbative QCD. A new technique which allows us to perform an algorithmic evaluation of inclusive phase-space integrals is introduced, based on the Cutkosky rules, integration by parts and the differential equation method for computing master integrals. Finally, we discuss the numerical impact of the [Omicron]([alpha]{sub s}2) QCD corrections to the Higgs boson production cross-section at the LHC and the Tevatron.

This thesis studies collider phenomenology of physics beyond the Standard Model at the Large Hadron Collider (LHC). It also explores in detail advanced topics related to Higgs boson and supersymmetry – one of the most exciting and well-motivated streams in particle physics. In particular, it finds a very large enhancement of multiple Higgs boson production in vector-boson scattering when Higgs couplings to gauge bosons differ from those predicted by the Standard Model. The thesis demonstrates that due to the loss of unitarity, the very large enhancement for triple Higgs boson production takes place. This is a truly novel finding. The thesis also studies the effects of supersymmetric partners of top and bottom quarks on the Higgs production and decay at the LHC, pointing for the first time to non-universal alterations for two main production processes of the Higgs boson at the LHC–vector boson fusion and gluon–gluon fusion. Continuing the exploration of Higgs boson and supersymmetry at the LHC, the thesis extends existing experimental analysis and shows that for a single decay channel the mass of the top quark superpartner below 175 GeV can be completely excluded, which in turn excludes electroweak baryogenesis in the Minimal Supersymmetric Model. This is a major new finding for the HEP community. This thesis is very clearly written and the introduction and conclusions are accessible to a wide spectrum of readers.

Michael Hauschild takes the reader of this essential back to the year 2012, when the discovery of the Higgs particle was announced at CERN, the European Organization for Nuclear Research near Geneva, Switzerland. The author vividly explains the Higgs mechanism for mass generation with the central role of the Higgs particle in current particle physics and the long hunt for its discovery at the Large Hadron Collider LHC. After a stop of more than two years, the LHC, the world‘s largest particle accelerator was put back into operation in spring 2015 to discover the secrets of nature at higher energy than ever before. An overview of future projects concludes this essential. This Springer essential is a translation of the original German 1st edition essentials, Neustart des LHC: die Entdeckung des Higgs-Teilchens by Michael Hauschild, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically different from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. The Content Mass does it! - How the particles get their mass From UFOs and more! - The LHC goes into the next round The plan of the century! - Higgs, what next? The Target groups Scientifically interested laymen and students Lecturers and students of the Studium Generale and the natural sciences The Author Dr. Michael Hauschild is a particle physicist at CERN in Geneva and has been a member of the ATLAS experiment at the Large Hadron Collider LHC since 2005. During the first long measurement period of the LHC from 2010 to 2012, he witnessed the discovery of the Higgs particle in summer 2012.

We present the cross-section for the threshold production of the Higgs boson at hadron-colliders at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD. We present an analytic expression for the partonic cross-section at threshold and the impact of these corrections on the numerical estimates for the hadronic cross-section at the LHC. With this result we achieve a major milestone towards a complete evaluation of the cross-section at N3LO which will reduce the theoretical uncertainty in the determination of the strengths of the Higgs boson interactions.
