  2. 1. Effective Distribution Theory

    Author : Fredrik Dahlgren; Viggo Stoltenberg-Hansen; Dag Normann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computable mathematics; computable analysis; domain theory; domain representations; distribution theory.; Mathematical logic; Matematisk logik;

    Abstract : In this thesis we introduce and study a notion of effectivity (or computability) for test functions and for distributions. This is done using the theory of effective (Scott-Ershov) domains and effective domain representations. READ MORE

  4. 2. Cluster Effective Field Theory

    Author : EMIL RYBERG; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; effective field theory; charge radius; resonant state; renormalization; radiative capture; halo nuclei; power counting; nuclear physics; few-body physics;

    Abstract : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. READ MORE

  5. 3. Deterrence Games for the 21st Century : Representation, Theory and Evidence

    Author : Karl Sörenson; Till Grüne-Yanoff; Jan Ångström; Damon Coletta; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Deterrence Theory; Game Theory; Theory of Science; Philosophy; Filosofi; Krigsvetenskap;

    Abstract : Deterrence is the backbone of military strategy. Dissuading an opponent from taking a specific action by threat of violence is the definition of deterrence. From the outset of the Cold War there has been a strong link between the study of deterrence and game theoretic analysis. READ MORE

  6. 4. Aspects of Yang-Mills Theory : Solitons, Dualities and Spin Chains

    Author : Lisa Freyhult; Antti Niemi; Poul Damgaard; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical Physics; Field theory; String theory; Yang-Mills; Effective models; Supersymmetry; Solitons; Fermion number; Duality; AdS CFT correspondence; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

    Abstract : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. READ MORE

  7. 5. Inference on Dark Matter in Effective Field Theories : From XENON1T towards XENONnT: Chiral effective field theory analysis of nuclear recoils, single electrons and uncommon background modelling

    Author : Vasile Cristian Antochi; Jan Conrad; Björn Penning; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; Direct Detection; Effective Field Theory; Chiral Effective Field Theory; Physics; fysik;

    Abstract : Cosmological and astronomical observations show that most of the matter in the Universe is dark. This dissertation provides an overview of the dark matter evidence, and focuses on the particle dark matter hypothesis, describing possible particle candidates, concentrating on the Weakly Interactive Massive Particles (WIMPs).
