1. Diffraction in high-energy collisions
Sammanfattning : This thesis concerns itself with low-momentum-transfer processes in high-energy particle collisions. These processes cannot be described in the framework of the fundamental theory of quantum chromodynamics (QCD), but rely on a pre-QCD approach, the Regge theory. LÄS MER
2. Color Screening in QCD and Neutrinos from Singlino Dark Matter
Sammanfattning : Hard diffraction in proton collisions, where the initial state proton emerges from the interaction rather undisturbed despite a hard interaction scale, has been studied for a few decades. First observed in proton-proton collisions, the phenomenon is seen as well in deep inelastic electron-proton scattering (DIS) as a leading final state proton and a rapidity gap-region without final state particles.

3. Correlations in multiparticle production
Sammanfattning : Different aspects of the strong interaction in particle collisions are studied. Most of the work is based on the Lund string fragmentation model for hadron production. A model which incorporates interference between identical bosons in the string model is presented. LÄS MER
4. Rope Hadronization, Geometry and Particle Production in pp and pA Collisions
Sammanfattning : This thesis concerns models of high energy collisions of sub-atomic particles, and the models’ implementation in numerical simulations; so–called Monte Carlo event generators. The models put forth in the thesis improves the description of soft collisions of protons, and takes the first steps towards a new, microscopic description of collectivity in proton collisions and collisions of heavy nuclei such as lead.

5. 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
