1. 1. Higgs Boson Decay to Two Photons : Probing the Standard Model

   University essay from Stockholms universitet/Fysikum

   Author : Daniel Slominski; [2022]
   Keywords : ;

   Abstract : The Higgs to Two Photon decay channel is analyzed to one-loop in the Feynman gauge.  Triangle loop processes are evaluated using dimensional regularization due to divergent integrals.  The build up to Higgs physics is given by way of gauge theories in the Standard Model where we can then introduce the Higgs field.

3. 2. Sunset integrals at finite volume

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Emil Boström; [2013]
   Keywords : Sunset integrals; loop integrals; Chiral Perturbation Theory; Lattice QCD; finite volume; Physics and Astronomy;

   Abstract : In this thesis we present a method for the calculation of finite volume corrections to the sunset diagram, for arbitrary masses and powers of the propagators. We also present numerical results showing the dependence of these corrections on the volume, which is an exponential decay for large volumes. READ MORE

4. 3. Investigation of Correlations Between COV of Ion Integral and COV of IMEP in a Port-Injected Natural-Gas Engine

   University essay from Institutionen för systemteknik

   Author : Johan Molin; [2008]
   Keywords : COV; IMEP; Ion current; EGR;

   Abstract : Correlations between the coefficient of variations (COV) of ion current integrals and COV of indicated mean effective pressure (IMEP) are investigated. The investigations are made to see if there is a possibility to use ion sense technique for closed loop combustion control to maximize Exhaust Gas Recirculation (EGR) level with remaining combustion stability.
