1. Multi-Meson Dynamics in Chiral Perturbation Theory
Sammanfattning : This thesis concerns scattering of light mesons in the case where the number of external particles exceeds four (that is, three or more particles in the initial or final state), calculated using chiral perturbation theory.This is both of theoretical interest in the study of scattering amplitudes, and relevant for systems of three or more pions simulated using lattice quantum chromodynamics.

2. Aspects of Porous Graphitic Carbon as Packing Material in Capillary Liquid Chromatography
Sammanfattning : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.

3. Green Chemistry in Chemical Education and Synthetic Applications of Sulfinamides
Sammanfattning : The preparation of chiral molecules, i.e. compounds that are not identical to their mirror image, is of great interest in the field of organic chemistry. LÄS MER
4. Higher Order Calculations for Low Energy Precision Physics
Sammanfattning : This thesis concerns higher order calculations needed for precision physics in the low energy region of particlephysics. Of the four papers it contains, the first two introduce calculations at order p8 in the power countingof chiral perturbation theory, which is an effective field theory of QCD at low energies. LÄS MER
5. Isospin Breaking in Kaon Decays to Pions
Sammanfattning : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. LÄS MER
