  1. 1. Predictions of Effective Models in Neutrino Physics

    Författare :Johannes Bergström; Tommy Ohlsson; Rikard Enberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrino mass; lepton mixing; Majorana neutrinos; effective field theory; Weinberg operator; seesaw models; low-scale seesaw models; inverse seesaw; right-handed neutrinos; renormalization group; threshold effects; neutrinoless double beta decay; Elementary particle physics; Elementarpartikelfysik;

    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.

  3. 2. Exploring effective descriptions of gauge fields and strings : A Lagrangian approach with insights from color-kinematics duality

    Författare :Lucia M. Garozzo; Henrik Johansson; Chris White; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scattering amplitudes; double copy; gauge theory; string theory; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The concept of a color-kinematics duality is an important driving force in advancing the modern understanding of scattering amplitudes, in both field theory and string theory. Yet, open questions remain that motivate the need for a deeper understanding of the duality. LÄS MER

  5. 4. Improved energy efficiency in double disc chip refining

    Författare :Dino Muhic; Per Engstrand; Lars Sundström; Mats Ullmar; Christer Sandberg; Hans Höglund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical pulping TMP ; double disc refining; high intensity; Chemical engineering; Kemiteknik;

    Sammanfattning : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. LÄS MER

  7. 5. Corporate Tax Integration and the Cost of Capital

    Författare :Tobias Lindhe; Paolo Panteghini; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Corporate Tax Integration; Economic Double Taxation; International Double Taxation; Cost of Capital; the New View of Equity; the Traditional View of Equity; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of an introduction and three self-contained chapters.Chapter I summarizes and relates the thesis to a larger context in the area of corporate tax integration. In particular, the main findings are related to the ongoing tax harmonization debate within the EU. LÄS MER
