Supersymmetry (SUSY) is a new symmetry that relates bosons and fermions, which has strong support at both the mathematical and the physical level. This book offers a comprehensive review, following the development of SUSY from its very early days up to present. The order of the contributions should provide the reader with the historical development as well as the latest theoretical updates and interpretations, and experimental constraints from particle accelerators and dark matter searches. It is a great pleasure to bring together here contributions from authors who initiated or have contributed significantly to the development of this theory over so many years. To present a balanced point of view, the book also includes a closing contribution that attempts to describe the physics beyond the Standard Model in the absence of SUSY. The contributions to this book have been previously published in The European Physical Journal C - Particles and Fields.

This thesis focuses on the theoretical foundation of the Standard Model valid up to the Planck scale, based on the current experimental facts from the Large Hadron Collider. The thesis consists of two themes: (1) to open up a new window of the Higgs inflation scenario, and (2) to explore a new solution to the naturalness problem in particle physics. In the first area, on the Higgs inflation scenario, the author successfully improves a large value problem on a coupling constant relevant to the Higgs mass in the Standard Model, in which the coupling value of the order of 105 predicted in a conventional scenario is reduced to the order of 10. This result makes the Higgs inflation more attractive because the small value of coupling is natural in the context of ultraviolet completion such as string theory. In the second area, the author provides a new answer to the naturalness problem, of why the cosmological constant and the Higgs mass are extremely small compared with the Planck scale. Based on the baby universe theory originally proposed by Coleman, the smallness of those quantities is successfully explained without introducing any additional new particles relevant at the TeV energy scale.

Una brillante y esclarecedora explicación del experimento científico más importante de las últimas décadas. El bosón de Higgs ha sido descrito por muchos como el mayor avance en la comprensión de nuestro universo y como uno de los descubrimientos científicos más fascinantes de nuestro tiempo. Fundamental para comprender por qué existe la masa y por qué existen los átomos, esta escurridiza partícula ha sido hallada por fin después de una inversión de 9.000 millones de dólares, décadas de esfuerzo y el trabajo de cerca de seis mil investigadores en el Gran Colisionador de Hadrones de Ginebra. El físico del Caltech, Sean Carroll, lleva a los lectores entre los bastidores del Gran Colisionador de Hadrones en el CERN, para encontrarse con teóricos, ingenieros y experimentalistas, arroja luz sobre este hito científico y explica la ciencia del bosón de Higgs, erróneamente conocido como «la partícula divina». Con el bosón se descubre la última pieza del rompecabezas de la materia ordinaria: los átomos y las fuerzas que subyacen en todas partes, desde el ADN hasta el calentamiento global. Ahora se abre una puerta de entrada a lo extraordinario: el alucinante mundo de la materia oscura y más allá. La partícula al final del universo no solo explica la importancia del bosón de Higgs, sino también la del Gran Colisionador de Hadrones. Una historia de cómo el ansia de conocimiento del ser humano ha conducido el mayor logro científico de nuestro tiempo. Los expertos opinan... «Sean Carroll nos acompaña en un extraordinario viaje hacia el descubrimiento.» Frank Wilczek, premio Nobel de Física «Carroll nos cuenta la historia de la partícula de la que todo el mundo ha oído hablar pero pocos comprenden. Tras leer este libro -un cóctel de anécdotas, inteligentes analogías y pequeñas dosis de teoría alucinante-, entenderemos perfectamente por qué el bosón de Higgs ha sido perseguido durante tanto tiempo por tantos investigadores. [...] Contagioso e inspirador.» Morgan Freeman, actor y productor ejecutivo de Through the Wormhole «Sean Carroll ofrece una mirada lúcida y fascinante a la partícula más misteriosa y más importante de la naturaleza, y al experimento que la descubrió. Cualquiera que esté interesado en la física debería leer este libro.» Leonard Mlodinow «Con la agudeza y la lucidez que lo caracterizan, Carroll relata la historia de la búsqueda del escurridizo bosón de Higgs. [...] La claridad y el entusiasmo ilimitado de Carroll revelan lo apasionante del descubrimiento.» Publishers Weekly

On July 4th, 2012, one of physics' most exhilarating results was announced: a new particle – and very likely a new kind of particle – had been discovered at the Large Hadron Collider, the huge particle accelerator designed to reproduce energies present in the universe a fraction of a second after the Big Bang. The particle's existence had been speculated on for nearly fifty years: here, finally, was proof. Professor Lisa Randall of Harvard University is one of the world's most influential theoretical physicists, and author of the bestselling Knocking on Heaven's Door and Warped Passages. In Higgs Discovery she deftly explains both this epochal discovery and it's startlingly beautiful implications.

The Higgs Boson: Searching for the God Particle by the Editors of Scientific American Updated 2017 Edition! For the fifth anniversary of one of the biggest discoveries in physics, we’ve updated this eBook to include our continuing analysis of the discovery, of the questions it answers and those it raises. As the old adage goes, where there’s smoke, there’s fire. Where there is effect, there must be cause. The planet Neptune was found in 1846 because the mathematics of Newton's laws, when applied to the orbit of Uranus, said some massive body had to be there. Astronomers eventually found it, using the best telescopes available to peer into the sky. This same logic is applied to the search for the Higgs boson. One consequence of the prevailing theory of physics, called the Standard Model, is that there has to be some field that gives particles their particular masses. With that there has to be a corresponding particle, made by creating waves in the field, and this is the Higgs boson, the so-called God particle. This eBook chronicles the search – and demonstrates the power of a good theory. Based on the Standard Model, physicists believed something had to be there, but it wasn't until the Large Hadron Collider was built that anyone could see evidence of the Higgs – and finally in July 2012, they did. A Higgs-like particle was found near the energies scientists expected to find it. Now, armed with better evidence and better questions, the scientific process continues. This eBook gathers the best reporting and analysis from Scientific American to explain that process – the theories, the search, the ongoing questions. In essence, everything you need to know to separate Higgs from hype.

This Thesis describes the first measurement of, and constraints on, Higgs boson production in the vector boson fusion mode, where the Higgs decays to b quarks (the most common decay channel), at the LHC. The vector boson fusion mode, in which the Higgs is produced simultaneously with a pair of quark jets, provides an unparalleled opportunity to study the detailed properties of the Higgs, including the possibility of parity and CP violation, as well as its couplings and mass. It thus opens up this new field of study for precision investigation as the LHC increases in energy and intensity, leading the way to this new and exciting arena of precision Higgs research.

CERN, the European Laboratory for particle physics, regularly makes the news. What kind of research happens at this international laboratory and how does it impact people's daily lives? Why is the discovery of the Higgs boson so important? Particle physics describes all matter found on Earth, in stars and all galaxies but it also tries to go beyond what is known to describe dark matter, a form of matter five times more prevalent than the known, regular matter. How do we know this mysterious dark matter exists and is there a chance it will be discovered soon? About sixty countries contributed to the construction of the gigantic Large Hadron Collider (LHC) at CERN and its immense detectors. Dive in to discover how international teams of researchers work together to push scientific knowledge forward. Here is a book written for every person who wishes to learn a little more about particle physics, without requiring prior scientific knowledge. It starts from the basics to build a solid understanding of current research in particle physics. A good dose of curiosity is all one will need to discover a whole world that spans from the infinitesimally small and stretches to the infinitely large, and where imminent discoveries could mark the dawn of a huge revolution in the current conception of the material world.

The Higgs boson is an undiscovered elementary particle, thought to be a vital piece of the closely fitting jigsaw of particle physics. Like all particles, it has wave properties akin to those ripples on the surface of a pond which has been disturbed; indeed, only when the ripples travel as a well defined group is it sensible to speak of a particle at all. In quantum language the analogue of the water surface which carries the waves is called a field. Each type of particle has its own corresponding field. The Higgs field is a particularly simple one - it has the same properties viewed from every direction, and in important respects in indistinguishable from empty space. Thus physicists conceive of the Higgs field being switched on, pervading all of space and endowing it with grain like that of a plank of wood. The direction of the grain in undetectable, and only becomes important once the Higgs' interactions with other particles are taken into account. which case they move easily for large distances and may be observed as photons - that is, particles of light that we can see or record using a camera; or against, in which case their effective range is much shorter, and we call them W or Z particles. These play a central role in the physics of nuclear reactions, such as those occurring in the core of the sun. The Higgs field enables us to view these apparently unrelated phenomenon as two sides of the same coin; both may be described in terms of the properties of the same vector bosons. When particles of matter such as electrons or quarks (elementary constituents of protons and neutrons, which in turn constitute the atomic nucleus) travel through the grain, they are constantly flipped head-over-heels, this forces them to move more slowly than their natural speed, that of light, by making them heavy.
