Neutrinos and Primordial Nucleosynthesis [PDF]

Nuclear Physics B - Proceedings Supplements, 2005
The importance of the Big Bang Nucleosynthesis (BBN) as a unique tool for studying neutrino properties is discussed, and the recent steps towards a self-consistent and robust handling of the weak reaction decoupling from the thermal bath as well as of the neutrino reheating following the e+e- annihilation are summarized. We also emphasize the important

The Nuclear Astrophysics program at n_TOF (CERN)

EPJ Web of Conferences, 2017
An important experimental program on Nuclear Astrophysics is being carried out at the n_TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis.

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

Annalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Neutron Diffusion and Nucleosynthesis in an Inhomogeneous Big Bang Model

, 2005
This article presents an original code for Big Bang Nucleosynthesis in a baryon inhomogeneous model of the universe. In this code neutron diffusion between high and low baryon density regions is calculated simultaneously with the nuclear reactions and ...

Modeling of Cosmogenic Cr Isotopes Produced in Lunar Rocks Compared With Existing Calculations and Measurements

Journal of Geophysical Research: Planets, Volume 129, Issue 2, February 2024.
Abstract The nucleosynthetic Cr isotope anomalies provides useful information to trace the source and origin of extraterrestrial samples, but it is usually influenced by high‐energy cosmic rays, and evaluating such effect of cosmic rays in lunar samples is especially important.

Second Order Corrections to the Magnetic Moment of Electron at Finite Temperature

, 2013
Magnetic moment of electron at finite temperature is directly related to the modified electron mass in the background heat bath. Magnetic moment of electron gets modified when it couples with the magnetic field at finite temperature through its ...

Nuclear astrophysicists at war

Natural Sciences, Volume 4, Issue 1, January 2024.
The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Absence of a Lower Limit on Omega_b in Inhomogeneous Primordial Nucleosynthesis

, 1994
We show that a class of inhomogeneous big bang nucleosynthesis models exist which yield light-element abundances in agreement with observational constraints for baryon-to-photon ratios significantly smaller than those inferred from standard homogeneous ...
