Book Description
Run 1 of the Large Hadron Collider (LHC) has been one of the most successful experiments in particle physics. We are now approaching the end of LHC Run 2, and whether we will discover new physics or not, the high energy particle physics community is already inspecting various possibilities for the future generation of colliders. One of the most intriguing scenarios deals with the exploration of energies so far not reached, with energy scales up to several TeVs, as for example a $\sqrt{s} = 100 $ TeV hadron-hadron collider. This thesis inspects the phenomenological potential of such a machin...

Book Description
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.

Book Description
Supersymmetric theories, such as the Minimal Supersymmetric Standard Model (MSSM), constitute very popular extensions of the Standard Model of particle physics that are extensively searched for at the Large Hadron Collider (LHC). In this thesis, we focus on two specific aspects of the phenomenology of supersymmetric theories at high-energy hadron colliders, namely polarized collisions and precision calculations. First, we perform a Leading Order (LO) study, in which we show how the availability of (longitudinally) polarized proton beams could us help us to disentangle various Beyond the Standard Model (BSM) scenarios exhibiting the same final-state signature. For the sake of illustration, we focus on the case of one particular class of scenarios leading to monotop production, which corresponds to the production of a top quark in association with missing transverse energy. We present our results for a polarized LHC at 14 TeV, and for the recently proposed Future Circular Collider (FCC), supposed to operate at 100 TeV. Then, we concentrate on precise predictions for the pair production of coloured supersymmetric particles at next-to-leading order (NLO) in supersymmetric QCD, with or without Non-Minimal Flavour Violations (NMFV), and with or without matching those predictions with Parton Showers (PS). More specifically, we provide the first preliminary results for squark-antisquark pair production at NLO in SUSY-QCD with NMFV, in the case of a fixed order calculation, and consider in the context of simplified models the pair production of coloured scalar and coloured Majorana particles at NLO matched with PS.

Book Description
The Standard Theory of Particle Physics describes successfully the observed strong and electroweak interactions, but it is not a final theory of physics, since many aspects are not understood: (1) How can gravity be introduced in the Standard Theory? (2) How can we understand the observed masses of the leptons and quarks as well as the flavor mixing angles? (3) Why are the masses of the neutrinos much smaller than the masses of the charged leptons? (4) Is the new boson, discovered at CERN, the Higgs boson of the Standard Theory or an excited weak boson? (5) Are there new symmetries at very high energy, e.g. a broken supersymmetry? (6) Are the leptons and quarks point-like or composite particles? (7) Are the leptons and quarks at very small distances one-dimensional objects, e.g. superstrings? This proceedings volume comprises papers written by the invited speakers discussing the many important issues of the new physics to be discovered at the Large Hadron Collider.

Book Description
With the Large Hadron Collider (LHC) under construction and due to come online in 2007, it is appropriate to engage in a focused review on LHC phenomenology. At a time when most of the experimental effort is centered on detector construction and software development, it is vitally important to direct the experimental community and, in particular, new researchers on the physics phenomena expected from the LHC. Large Hadron Collider Phenomenology covers the capabilities of LHC, from searches for the Higgs boson and physics beyond the standard model to detailed studies of quantum chromodynamics, the B-physics sectors, and the properties of hadronic matter at high energy density as realized in heavy-ion collisions. Written by experienced researchers and experimentalists, this reference examines the basic properties and potentials of the machine, detectors, and software required for physics analyses. The book starts with a basic introduction to the standard model and its applications to the phenomena observed at high energy collisions. Later chapters describe the key technological challenges facing the construction of the LHC machine, the operating detectors of the LHC, and the vast computing grid needed to analyze the data. In the final sections, the contributors discuss the quark-gluon plasma (QGP), explore questions and predictions for the LHC program, and examine the physics opportunities of the LHC using information from the forward region. By surveying the difficult challenges of the LHC development while also assessing the novel processes that the LHC will perform, Large Hadron Collider Phenomenology aids less seasoned physicists as well as existing researchers in discovering the numerous possibilities of the LHC.

Book Description
Despite the tremendous success of the Standard Model (SM), it needs to be extended to explain the origin of cosmological inflation, dark matter (DM) and neutrino masses. We consider gauged U(1)x extended SM, where in addition to the SM particles, the model includes a U(1)x scalar, Z' gauge boson, and three generations of right-handed neutrinos (RHNs), where the U(1)x charges of all the particles are defined by a single free parameter xH. In this model context, we discuss the complementarity between the cosmological inflation, the DM physics, and new physics searches at the Large Hadron Colliders (LHC). With the identification of the U(1)x scalar as an inflaton field, we consider the cosmological inflation scenario. For an effective inflaton potential to develop an inflection-point with predictions consistent with cosmological observations, the mass ratios among the Z' boson, the RHNs, and the inflaton are fixed. Requiring the inflationary prediction to be consistent with the current cosmological observation and collider experimental results, we show that our scenario can be tested at the future collider experiments such as the High Luminosity-LHC and the SHiP experiment. We also consider SU(5) x U(1)x scenario, where the SU(5) grand unification of the SM quarks and leptons is realized for xH = -4/5. Hence, the U(1)x charge is quantized in this scenario. With an additional global Z-2 symmetry, one RHN, which is Z-2 odd particles, serves as the DM in the universe. We investigate the Z'-portal RHN DM scenario and find that the constraints from the DM relic abundance and the search results for a Z' boson resonance at the LHC Run-2 are complementary to narrow down the allowed parameter region, which will be fully covered by the future LHC experiments for the Z' boson mass less than 5 TeV.

Book Description
The monumental discovery of the Higgs boson at the LHC marked the beginning of a new era in the high energy physics. Although the particle spectrum of the Standard Model is now complete with the Higgs boson, the hierarchy problem and the lack of explanation of the origin of dark matter imply that a new Beyond the Standard Model physics should exist. There is however no clear indication (experimental or otherwise) of the energy scale at which this new physics should appear. Current results from the LHC experiments have shown no unpredicted effects up to pp collision energies of 13 TeV. If not observed directly at the LHC, the new physics may reveal itself through deviations of Higgs properties from their Standard Model expectations, or it may become directly accessible only at new, higher-energy accelerator facilities. It is then of primary importance to have a comprehensive review of the available and planned accelerators and their design, physics motivation and expected performance.This book comprises 26 carefully edited articles with well-referenced and up-to-date material written by many of the leading experts. These articles — originated from presentations and dialogues at the second HKUST Institute for Advanced Study Program on High Energy Physics — are organized into three aspects, Theory, Accelerator, and Experiment, focusing on in-depth analyses and technical aspects that are essential for the developments and expectations for the future high energy physics.
