Non-standard interactions (NSI) between active neutrinos (neutrinos belonging to the Standard Model) have the potential to modify the production of a fourth type of keV-scale mass neutrino (called "sterile"), due to active-sterile neutrino oscillations in the early Universe, a process known as the Dodelson-Widrow mechanism (DW). Through this modified DW mechanism, enough sterile neutrinos could be produced to account for the whole of the dark matter. This type of dark matter production occurred before big bang nucleosynthesis (BBN), an era just before the temperature of the Universe settled to 5 MeV, which is currently unknown. Thus, this type of dark matter production can be explored with different pre-BBN cosmological models. Taking into consideration the uncertainties in the pre-BBN cosmology besides the effects of NSI, we may identify a viable parameter space for sterile neutrino searches allowed by astrophysical limits and assess their effect on the range of mixing angles for keV-scale mass sterile neutrino dark matter. Detection of a sterile neutrino could provide insight into the pre-BBN era of the Universe. We find that the combined uncertainties in the early Universe cosmologies, as well as in the active neutrino interactions, significantly expand the allowed parameter space for sterile neutrinos that could constitute the whole of the dark matter. This thesis work will be published in a paper with the same title by C. Chichiri, G. Gelmini, P. Lu and V. Takhistov, already posted as a preprint in the arXiv,e-Print: 2.111.04087[hep-ph], and submitted for publication to the Journal of Cosmology and Astroparticle Physics (JCAP).

This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.

This book describes these issues in terms of links, between cosmology, particle and nuclear physics, as well as between cosmology, atmospheric and terrestrial physics. It studies the constituents of dark matter (classified as hot warm and cold) first in terms of their individual structures, and second, in terms of facilities available to detect these structures. Neutrinos are treated as a separate entity. The last chapter details the real-time stories about the "regions" that were not explored thus far, for lack of advanced technology. Their untold stories (which span up to 2010) are illustrated here datewise in full. The book concludes with the latest news that the Large Hadron Collider team at CERN has finally succeeded in producing 7 trillion electronic Volts of energy by creating head-on-collisions of protons and more protons (in search of God-particle).

The role that neutrinos have played in the evolution of the Universe is the focus of one of the most fascinating research areas that has stemmed from the interplay between cosmology, astrophysics and particle physics. In this self-contained book, the authors bring together all aspects of the role of neutrinos in cosmology, spanning from leptogenesis to primordial nucleosynthesis, their role in CMB and structure formation, to the problem of their direct detection. The book starts by guiding the reader through aspects of fundamental neutrino physics, such as the standard cosmological model and the statistical mechanics in the expanding Universe, before discussing the history of neutrinos in chronological order from the very early stages until today. This timely book will interest graduate students and researchers in astrophysics, cosmology and particle physics, who work with either a theoretical or experimental focus.

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and particle physics - in each case viewed from both theoretical and experimental/observational perspectives. After reviewing the role of active neutrinos in particle physics, astrophysics, and cosmology, we focus on sterile neutrinos in the context of the Dark Matter puzzle. Here, we first review the physics motivation for sterile neutrino Dark Matter, based on challenges and tensions in purely cold Dark Matter scenarios. We then round out the discussion by critically summarizing all known constraints on sterile neutrino Dark Matter arising from astrophysical observations, laboratory experiments, and theoretical considerations. In this context, we provide a balanced discourse on the possibly positive signal from X-ray observations. Another focus of the paper concerns the construction of particle physics models, aiming to explain how sterile neutrinos of keV-scale masses could arise in concrete settings beyond the Standard Model of elementary particle physics. The paper ends with an extensive review of current and future astrophysical and laboratory searches, highlighting new ideas and their experimental challenges, as well as future perspectives for the discovery of sterile neutrinos.

Download Neutrino Physics: Its Impact On Particle Physics, Astrophysics And Cosmology - Proceedings Of The Carolina Symposium On Neutrino Physics Book in PDF, ePub and Kindle
Neutrinos play a key role in many areas of particle physics, nuclear physics and astrophysics. The recent discovery of neutrino oscillation has given the first hint of new physics beyond the standard model. Clearly, it is extremely important to study further the oscillation and other fundamental properties of neutrinos. It is also important to improve our knowledge of neutrino-nucleus reactions, which are crucial for understanding a large class of astrophysical phenomena. These and many other interesting questions can be investigated at stopped pion neutrino facilities like the one planned for the Spallation Neutron Source at the Oak Ridge National Laboratory.The purpose of the Carolina Symposium was twofold: (1) to explore and exchange ideas on the latest developments in general frontiers of neutrino physics and related fields; (2) to address specific issues pertaining to the above-mentioned stopped pion neutrino facility. Among the topics covered in the proceedings are: cosmology and neutrino; standard model tests with neutrinos; neutrino oscillation, experiments and theories; dark matter search; double beta-decay; rare events detection techniques; the solar neutrino problem; supernova explosion; nucleosynthesis; and the ORLaND project.

In this essential, Claus Grupen discusses astroparticle physics in a short historical outline and describes the latest results without going into mathematical detail. As an introduction to this new field of research, he gives an overview of what happens in the sky, between stars and between galaxies. By now, many things are quite well understood, but with every solution found, new questions arise - the author also deals with this spectrum of questions with some answers. Today, astroparticle physics is an active, interdisciplinary field of research that includes and combines astronomy, cosmic rays and elementary particle physics. This Springer essential is a translation of the original German 1st edition essentials, Neutrinos, Dunkle Materie und Co. by Claus Grupen, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2021.The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors

Much of what we know about neutrinos is revealed by astronomical observations, and the same applies to the axion, a conjectured new particle that is a favored candidate for the main component of the dark matter of the universe.
