1. Soft resummation and hard evolution : Renormalization group methods in effective theories and multi scalar models
Sammanfattning : This thesis is composed out of five papers that deal with various problems intheoretical particle physics. While paper I is a precision calculation in aneffective theory of the Standard Model, paper II to V all deal with beyond theStandard Model physics. Paper IV is a manual for the tools developed during ourwork on paper II to V.Paper I. LÄS MER
2. Phenomenology of SO(10) Grand Unified Theories
Sammanfattning : Although the Standard Model (SM) of particle physics describes observations well, there are several shortcomings of it. The most crucial of these are that the SM cannot explain the origin of neutrino masses and the existence of dark matter. LÄS MER
3. Predictions of Effective Models in Neutrino Physics
Sammanfattning : Experiments on neutrino oscillations have confirmed that neutrinos have small, but non-zero masses, and that the interacting neutrino states do not have definite masses, but are mixtures of such states.The seesaw models make up a group of popular models describing the small neutrino masses and the corresponding mixing.

4. Models of SO(10) Grand Unified Theories : Yukawa Sector and Gauge Coupling Unification
Sammanfattning : .... LÄS MER
5. On transport theory of correlated mesoscopic systems
Sammanfattning : This thesis is about the theory of quantum transport through low dimensional correlated systems. Correlated systems are interacting many-particle systems where collective effects predominate over the individual properties of particles whereof they consist. Single particle approach to correlated systems would be essentially wrong. LÄS MER
