1. 1. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Filip Ekblom; [2023]
   Keywords : Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

   Abstract : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. READ MORE

3. 2. Fitting the three loop pion mass and decay constant to lattice data

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Alexandra Wernersson; [2019]
   Keywords : Chiral Perturbation Theory; Lattice QCD; pion mass; decay constant; three loop fit.; Physics and Astronomy;

   Abstract : We perform a fit to three loop order (NNNLO) in Chiral perturbation theory of the pion mass and decay constant. In particular we investigate if the NNNLO fit is an improvement of the fit to two loop order (NNLO) to lattice QCD data, which was done in a lattice gauge group collaboration. READ MORE
