  2. 6. Dynamics of quarks and leptons : theoretical Studies of Baryons and Neutrinos

    Author : Tommy Ohlsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chiral quark model; baryons; conguration mixing; magnetic moments; Coleman{Glashow sum-rule; spin structure; spin polarizations; weak form factors; semileptonic decays; nucleon quark sea isospin asymmetry; neutrinos; neutrino oscillations; neutrino avors; mixing angles; mass squared dierences; MSW eect; numerical calculations; interpretation of experiments; Mathematical physics; Matematisk fysik;

    Abstract : The Standard Model of Elementary Particle Physics (SM) is the present theoryfor the elementary particles and their interactions and is a well-established theorywithin the physics community. The SM is a combination of Quantum Chromodynamics(QCD) and the Glashow{Weinberg{Salam (GWS) electroweak model. READ MORE

  4. 7. Meson Properties in Partially Quenched Effective Field Theory

    Author : Niclas Danielsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Chiral Perturbation Theory; masses; decay constants; Physics; electromagnetic interactions; Strong interactions; pseudoscalar mesons; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

    Abstract : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. READ MORE

  5. 8. Fundamental properties of neutrinos: masses and mixings

    Author : Solveig Skadhauge; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; Fysik; Physics; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; statistical physics; gravitation; relativity; statistisk fysik; termodynamik; thermodynamics; klassisk mekanik; kvantmekanik; relativitet; Fysicumarkivet A:2002:Skadhauge;

    Abstract : Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. READ MORE

  6. 9. Structure of Deformed Proton-rich Nuclei Studied by Beta-decay

    Author : Petter Urkedal; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; termodynamik; statistisk fysik; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; gravitation; statistical physics; Physics; nuclear-structure beta-decay proton-rich drip-line neutrino; Fysik; Fysicumarkivet A:2002:Urkedal;

    Abstract : Nuclear structure is studied using beta-decay reactions as a probe and focusing on medium-heavy proton-rich nuclei. One of the included articles is a systematic study covering a major part of the nuclear chart, especially searching for nuclei which may be sensitive to sub-MeV neutrinos... READ MORE

  7. 10. Quantum scattering and interaction in graphene structures

    Author : Anna Orlof; Vladimir Kozlov; Igor Zozoulenko; Heinz Siedentop; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Since its isolation in 2004, that resulted in the Nobel Prize award in 2010, graphene has been the object of an intense interest, due to its novel physics and possible applications in electronic devices. Graphene has many properties that differ it from usual semiconductors, for example its low-energy electrons behave like massless particles. READ MORE
