   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrino mass; lepton mixing; Majorana neutrinos; neutrino oscillations; neutrinoless double beta decay; statistical methods; Bayesian inference; model selection; effective field theory; Weinberg operator; seesaw models; inverse seesaw; right-handed neutrinos; renormalization group; threshold effects.; Neutrinomassor; leptonblandning; Majorananeutriner; neutrinooscillationer; neutrinol¨ost dubbelt betas¨onderfall; statistiska metoder; Bayesisk inferens; modellval; effektiv f¨altteori; Weinbergoperator; seesawmodeller; invers seesaw; högerhänta neutriner; renormeringsgrupp; tröskeleffekter.;

   Sammanfattning : The standard model of particle physics can excellently describe the vast majorityof data of particle physics experiments. However, in its simplest form, it cannot account for the fact that the neutrinos are massive particles and lepton flavorsmixed, as required by the observation of neutrino oscillations. LÄS MER

3. 2. Predictions of Effective Models in Neutrino Physics

   Författare :Johannes Bergström; Tommy Ohlsson; Rikard Enberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrino mass; lepton mixing; Majorana neutrinos; effective field theory; Weinberg operator; seesaw models; low-scale seesaw models; inverse seesaw; right-handed neutrinos; renormalization group; threshold effects; neutrinoless double beta decay; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : Experiments on neutrino oscillations have confirmed that neutrinos have small, but non-zero masses, and that the interacting neutrino states do not have definite masses, but are mixtures of such states.The seesaw models make up a group of popular models describing the small neutrino masses and the corresponding mixing.
