Abstract

"The ultimate question of elementary particle physics is : What is the fundamental Lagrangian of nature surrounding us ? The Lagrangian of the SM is very successful in describing nature at the currently available energy range. The discovery of the Higgs boson completed the particle spectrum of the SM and it is another proof of how well the SM works. Nevertheless the SM cannot be the end of the story and it is for sure not the fundamental Lagrangian of nature. The Lagrangian of the SM looses its validity at the latest at the Planck scale where gravitational effects become noticeable.Most physicists think of the SM as an effective theory that has to be replaced by a more fundamental theory above the TeV scale. What the word effective really means will hopefully be clear at later stages of our book. For the time being we will list some problems and open questions of the SM."--

Abstract

This monograph treats the effectiveness of using flavor physics in offering probes of the TeV scale, while providing a timely interface during the emerging LHC era. By concentrating only with the TeV-scale connection, a large part of the B factory output can be bypassed, and emphasis is placed on loop-induced processes, i.e. virtual, quantum processes that probe TeV-scale physics. The experimental perspective is taken, resulting in selecting processes, rather than the theories or models, as the basis to exploration. Two-thirds of the book is therefore concerned with b -> s or bs <-> sb transitions. The guiding principle is: unless it can be identified as the smoking gun, it is better to stick to the simplest, rather than elaborate, explanation of an effect that may call for New Physics. By focusing on heavy flavor as a probe of TeV-scale physics, technicalities can be employed to unveil their beauty, without getting ensnared in them, while aiming for the deeper, higher-scale physics that such probes provide. This tract originated from a plenary talk at the SUSY 2007 conference in Karlsruhe, Germany.

Abstract

The production of heavy quarks in high-energy experiments offers a rich field to study, both experimentally and theoretically. Due to the additional quark mass, the description of these processes in the framework of perturbative QCD is much more demanding than it is for those involving only massless partons. In the last two decades, a large amount of precision data has been collected by the deep inelastic HERA experiment. In order to make full use of these data, a more precise theoretical description of charm quark production in deep inelastic scattering is needed. This work deals with the first calculation of fixed moments of the NNLO heavy flavor corrections to the proton structure function F2 in the limit of a small charm-quark mass. The correct treatment of these terms will allow not only a more precise analysis of the HERA data, but starting from there also a more precise determination of the parton distribution functions and the strong coupling constant, which is an essential input for LHC physics. The complexity of this calculation requires the application and development of technical and mathematical methods, which are also explained here in detail.
