6. The colour of gluon interactions : Studies of Quantum Chromodynamics in soft and hard processes
Sammanfattning : Quantum Chromodynamics (QCD) is the theory of the strong interaction, one of the fundamental forces of nature. The interactions between quarks are mediated by gluons, which are the colour-charged gauge fields in QCD. LÄS MER
7. A Study of Parton Dynamics from Deep Inelastic Scattering Events Containing a Jet in the Forward Direction
Sammanfattning : The DIS ep-scattering parton dynamics at low-x is characterised by an initial state cascade in which the virtualities of the propagator gluons are expected to take any kinematically allowed value, in contrast to the leading log behaviour. These dynamics might be enhanced by selecting events in which an energetic jet is found in the forward angular region at HERA, 1. LÄS MER
8. Interplay between soft and hard processes in quantum chromodynamics
Sammanfattning : In QCD, the theory of strong interactions, hard processes with large momentum transfers can be calculated using perturbation theory, while soft processes with small momentum transfers are poorly understood. In this thesis, phenomenological models of soft and hard QCD processes are developed and tested. LÄS MER
9. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics
Sammanfattning : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. LÄS MER
10. Phenomenology of new Neutral Vector Bosons and Parton Distributions from Hadronic Fluctuations
Sammanfattning : The Higgs particle was first predicted in 1964, and was discovered in the summer of 2012 at the Large Hadron Collider (LHC). This discovery was the latest in a long list of successful Standard Model predictions spanning the last fifty years. LÄS MER
