Book Description
The Large Hadron Collider (LHC) is currently the world's premier facility for the study of high-energy particle physics. The goal of the Compact Muon Solenoid (CMS) experiment at the LHC is to search for new phenomena in particle physics at the TeV scale. One of the mysteries that data from CMS may solve is the origin of dark matter. It is hoped that dark matter particles will be produced in the proton-proton collisions of the LHC, either by themselves or along with other new particles. This would allow the laws that govern dark matter to be explored. Collisions containing dark matter particles will pose new challenges for collider physics, necessitating the development of new methods to deal with these problems. One class of methods for addressing these problems is kinematic endpoint variables such as MT2 and MCT. A great deal of theoretical work has been done in developing these methods, but they have seldom been applied in experiment. We apply these methods to data taken with CMS to address two problems: mass measurement in underconstrained events and searches for new physics. In doing so, we also provide a new measurement of the top-quark mass and search for new physics in events with two leptons and a momentum imbalance.

Book Description
The Large Hadron Collider (LHC), located at CERN, Geneva, Switzerland, is the world's largest and highest energy and highest intensity particle accelerator. Here is a timely book with several perspectives on the hoped-for discoveries from the LHC.This book provides an overview on the techniques that will be crucial for finding new physics at the LHC, as well as perspectives on the importance and implications of the discoveries. Among the accomplished contributors to this book are leaders and visionaries in the field of particle physics beyond the Standard Model, including two Nobel Laureates (Steven Weinberg and Frank Wilczek), and presumably some future Nobel Laureates, plus top younger theorists and experimenters. With its blend of popular and technical contents, the book will have wide appeal, not only to physical scientists but also to those in related fields.

Book Description
This Ph.D. thesis is a search for physics beyond the standard model (SM) of particle physics, which successfully describes the interactions and properties of all known elementary particles. However, no particle exists in the SM that can account for the dark matter, which makes up about one quarter of the energy-mass content of the universe. Understanding the nature of dark matter is one goal of the CERN Large Hadron Collider (LHC). The extension of the SM with supersymmetry (SUSY) is considered a promising possibilities to explain dark matter. The nominated thesis describes a search for SUSY using data collected by the CMS experiment at the LHC. It utilizes a final state consisting of a photon, a lepton, and a large momentum imbalance probing a class of SUSY models that has not yet been studied extensively. The thesis stands out not only due to its content that is explained with clarity but also because the author performed more or less all aspects of the thesis analysis by himself, from data skimming to limit calculations, which is extremely rare, especially nowadays in the large LHC collaborations.

Book Description
The world beyond Superstrings describes a world with dimensions smaller than Planck length (1.616229 x 10-35 [m] ). Since 1971 Superstrings within the dimensions of the Planck length have been considered the building elements for elementary particles . The question rises: What are Superstrings made of? What is the building material for Superstrings. What are the 10 dimensions? This book offers an attempt to find new answers beyond unknown borders. To find the new unknown boundaries we have to go back in time. Because when we start with the same mathematical equations, the same knowledge, the same procedures, we will always find the same outcome, the same answers. And soon we will believe that there is only one outcome. The only outcome within the Standard Model where we will find the same elementary particles grounded on the same Superstring Theory. To escape from the vicious circle in Quantum Mechanics, we have to leave the path of well known physics. We have to leave behind the founders of Quantum Physics. Great scientists like Niels Bohr and Werner Heisenberg. We have to leave behind the safe path of well- known physics. We even have to leave behind the founders of classical physics. We have to leave behind a very special scientist like James Clerk Maxwell, the founder of Classical Electrodynamics. And when we walk all alone in darkness, wondering where to go, we have to remember the first beginning of the discovery of light. How a man, half a monk, half a scientist, like Isaac Newton discovered the first principles of the light when he saw the first secrets of light being revealed. When the pure white light was broken through a prism and separated in the colors of the rainbow. Isaac Newton was touched by the beauty of the light as well as in his religious way as well as in his scientific way. And that is the secret that the world has forgotten. Everything will be revealed to us, when we step down from our towers of power and kneel humble for the beauty of that what has been given to us. Because there is wisdom in beauty. There is knowledge in prayer. And the most powerful wisdom will be given to us out of love. Do not claim wisdom but receive it humble and enjoy the beauty of it. There is nothing more “non-scientific” in the world than to claim that we have found the “God’s particle”. There is nothing more arrogant in the world than to claim that we have found the theory of everything and that we have framed God into a quantum mechanical box. But when we make ourselves humble and kneel for the beauty of the world. When we open our heart for the love that is carried by the beauty, wisdom will come to us and answers will be given for free. Doors will be opened. And we will discover the secrets to open the hidden doors to the unknown worlds. When we go back in time, back to 1672 when Isaac Newton just had discovered the beauty of light, showing all its hidden colors. And we ask the “hidden world showing the beauty of light”: how can we build a world? We will simply find the answers. And knowledge will be given to us for free. Knowledge beyond Superstrings. Knowledge beyond 10-dimensional spaces. Because the world is always in balance. Newton’s second law of motions simply expresses the balance in nature. And balance will be our answer. To build a world, we have to build a world in balance. And that is the only knowledge that has been used to build a new theory beyond Superstrings and beyond 10-dimensional spaces. The discovery journey to this new theory beyond Superstrings will be lonely and dark. Because there will be no guidance from well known physics. Equations have to be reinvented. And the road will lead straight through faith and believe, through manipulation of truth, through political intrigues, through the darkness of the world. But there is always the hope that at the end of the tunnel of darkness, there will be light.
