    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 38. Properties of baryons in the chiral quark model

    Författare :Tommy Ohlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chiral quark model; baryons; configuration mixing; magnetic moments; Coleman-Glashow sum-rule; spin polarizations; weak form factors; semilepronic decays; Physics; Fysik;

    Sammanfattning : In this thesis, several properties of baryons are studied using the chiral quark model. The chiral quark model is a theory which can be used to describe low energy phenomena of baryons. In Paper 1, the chiral quark model is studied using wave functions with configuration mixing.

  5. 39. District Heating for Residential Areas with Single-Family Housing -with Special Emphasis on Domestic Hot Water Comfort

    Författare :Tommy Persson; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low heat density; District heating; single-family housing; domestic hot water comfort; domestic hot water control; heat losses; supply temperature; thermostatic valves; Energiforskning; Energy research; marketing strategies; market penetration;

    Sammanfattning : The concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. LÄS MER
