1. 1. ALPACA - A kinetic theory Monte Carlo event generator for heavy ion collisions

   Författare :Robin Törnkvist; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ALPACA; QCD effective kinetic theory; event generators; heavy-ion physics; Proton-proton collisions; small system collectivity; phenomemology;

   Sammanfattning : Recent measurements of collective effect-like signals in small collision systems has highlighted the need for new models to explain these phenomena. One good candidate for such a model is the AMY QCD effective kinetic theory, which is valid for systems in- and out-of-equilibrium. LÄS MER

3. 2. Aspects of QCD and the Photon Structure

   Författare :Christer Friberg; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; QCD; Photons; Monte Carlo Event Generator; Leptoquarks; Colour Connections; cosmic rays; Kosmisk strålning; högenergi; Fysicumarkivet A:2000:Friberg;

   Sammanfattning : In a single theoretical framework, real and virtual photon interactions are modeled for gamma-p and gamma-gamma collisions. The description covers aspects from the production of jets to total cross sections, where special emphasis is put on the range of uncertainty in the modeling of a resolved photon component. LÄS MER

4. 3. Radiation and matter: how do they play with each other?

   Författare :Davide Mancusi; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy ions; models; transport codes; Boltzmann equation; Monte Carlo; radioprotection in space; radiotherapy; nuclear reactions;

   Sammanfattning : The propagation of radiation is affected by the presence of matter; at the same time, the physicochemical properties of matter are modified by the passage of radiation. The interplay of radiation and matter is of crucial importance in many modern applications: accelerated heavy ions, in particular, can be used in radiotherapeutical treatments of some cancers; moreover, they are present in the space radiation environment and represent a serious threat to the health of spaceship crews and to the functionality of electronic equipment on board.

5. 4. Structure Functions and Final-State Properties in Deeply Inelastic electron-proton Scattering

   Författare :Hamid Kharraziha; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmic rays; event generators; colour factors; High energy interactions; hadronic jets; QCD; the Linked Dipole Chain model; quantum mechanics; relativity; gravitation; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; Kosmisk strålning; högenergi; classical mechanics; Mathematical and general theoretical physics; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Kharraziha;

   Sammanfattning : In this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented.

7. 5. Diffraction in high-energy collisions

   Författare :Christine Rasmussen; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Soft QCD; phenomenology; Diffraction; Multiparton Interactions; Dipole model; Initial state evolution; BFKL evolution.; Fysicumarkivet A:2019:Overgaard;

   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
