  4. 2. Phenomenology of SO(10) Grand Unified Theories

    Author : Marcus Pernow; Tommy Ohlsson; Werner Rodejohann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grand unified theories; Renormalization group equations; Neutrino masses; Gauge coupling unification;

    Abstract : 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. READ MORE

  5. 3. Family symmetries and radiative corrections in multi-scalar extensions of the Standard Model

    Author : Jonas Wessén; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beyond the Standard Model; Trinification; Grand Unification; Three Higgs doublet models; Coleman-Weinberg potential; Supersymmetry; Left-Right symmetry; Fysicumarkivet A:2018:Wessén;

    Abstract : The four articles contained in this thesis all concern aspects of model building beyond the Standard Model (BSM). While Paper I mainly serves as a ``tool paper'' in which the results can be used to simplify certain calculations of one-loop effects from new heavy particles, Paper II--IV all deal with consequences of family symmetries in several BSM scenarios.

  6. 4. Studies of effective theories beyond the Standard Model

    Author : Stella Riad; Tommy Ohlsson; Mattias Blennow; Johan Rathsman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective field theories; neutrino physics; extra dimensions; universal extra dimensions; Higgs physics; renormalization group running; Bayesian statistics; coupling scale factor; grand unified theories;

    Abstract : The vast majority of all experimental results in particle physics can be described by the Standard Model (SM) of particle physics. However, neither the existence of neutrino masses nor the mixing in the leptonic sector, which have been observed, can be described within this model. READ MORE
