1. 1. Distribution of Neutrino Mixing Parameters FromReal and Complex Random Neutrino Mass Matrices

   Kandidat-uppsats, KTH/Teoretisk fysik

   Författare :Sammy Mannaa; Antek Szadaj; [2013]
   Nyckelord :;

   Sammanfattning : The theory of neutrino oscillations is covered. Also, the theory of Dirac, Majorana, and Dirac-Majorana neutrinos is presented. From this theory, and the model presented in [7], a program is constructed which creates a suitable number of neutrino mass matrices M using pseudo-random numbers generated in MATLAB. LÄS MER

3. 2. Triangle Loop in Scalar Decay and Cutting Rules

   L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Hazhar Ghaderi; [2013]
   Nyckelord :Cutkosky cutting rules; Feynman triangle loop diagram; two-fold Dirac delta functions; double Dirac delta functions; Dirac delta distribution; delta distribution;

   Sammanfattning : In this report we will calculate the amplitude for a scalar-to-scalars (φ3  φ2φ2) decay which involves a triangle loop. We compute the real and imaginary part of the amplitude separately and will argue that this is much more straightforward and practical in this case rather than having to deal with or worry about branch cuts of logarithms.
