Some of their most basic properties, such as their mass and charge conjugation symmetry, are largely unknown. In this thesis we will address three different phenomena related to neutrino physics. An efficient implementation of massive neutrinos in non. Linear and nonlinear massive neutrinos in cosmological nbody. Verifying how the sun shines has led to the discovery of neutrino flavor conversion and that neutrinos are massive. The propagation of massive neutrinos neutrino mass eigenstates are eigenstates of the freeparticle hamiltonian.

This third edition of the invaluable book massive neutrinos in physics and astrophysics is an introduction to the various issues related to the theory and. The decoupling of neutrinos, both light and possibly heavy ones, and the importance of neutrinos for nucleosyn thesis in the early universe are explained. This book focuses on what we know and may hope to know about the mass of the neutrino and its particleantiparticle. Naturally, this is not a proof that neutrinos have mass. Hdf5 file, which would then be read in from pkdgrav. Workshop for the next generation nucleon decay and neutrino detector. If we succeed in modelling the cosmic effects from massive neutrinos, we will then be able to extract the. If this is the case, a state produced as a e evolves in vacuum into. A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Massive stars fuse heavier elements in their cores than lower mass stars. Workshop for the next generation nucleon decay and neutrino. This leads to the creation of heavier elements up to iron.

Superkamiokande finds a deficit of muon neutrinos in the upgoing direction, corresponding to vacuum oscillation in the earth. Aspects of massive neutrinos in astrophysics and cosmology. Massive neutrinos make up a fraction of the dark matter, but due to their large thermal velocities. Introduction to massive neutrinos division of 20550. Neutrinos have half integer intrinsic angular momentum or spin. Recently, the neutrino oscillation phase due to the presence of gravity is much discussed 1, 2, 3. Majorana realized that you can give mass to particles in a more. Physics of massive neutrinos university of sheffield. Physics of massive neutrinos particle physics and particle. Massive neutrinos and the large scale structure of the universe. Iron robs critical energy from the core, causing it. In comparison, the known mixing of muon and tau neutrinos is consistent with being maximal, or 45 degrees. Also discussed is the role of baryonic, cold, and hot dark matter in the formation of largescale structures.

This thesis deals with the phenomenology of large scale structures in. With a pdf converter like pdfcreator, you have the possibility to upload your converted file directly to dropbox. The cosmic linear anisotropy solving system class iv. Abstract the observation that distant type ia supernovae, the explosive death of massive stars, were fainter than possible in a nonaccelerating expanding universe lead to one of. Wong rwth aachen theory colloquium, padova, november 18, 2009. In particular the most stringent limit is obtained from tritium decay for the electron neutrino.

The neutrino mass mechanism described here leads to parametrically small dirac neutrino masses, and the model also requires the existence of at least four dirac sterile neutrinos. The article begins with the general phenomenology of neutrino oscillations in vacuum and matter and documents the experimental evidence for. Neutrinos play a decisive part in nuclear and elementary particle physics, as well as in astrophysics and cosmology. The effect of these massive neutrinos would be to suppress the growth of dense structures that lead to the formation of. A possible way of resolving this discrepancy is for neutrinos to have mass. One can construct grand unified theories in which the neutrinos are presumed to be massless, and their masslessness is put in by hand. The properties of massive majorana neutrinos and of their various possible couplings. Atmospheric neutrinos atmospheric neutrinos are generated by the interaction of cosmic ray protons with the upper atmosphere, producing pions whose decays yield muon and electron neutrinos in the ratio 2. Oddly, then, while neutrinos play so lively a part in the world around us, we know.
