Underground measurement at LUNA found no evidence for a low-energy resonance in the 6Li(p, γ)7Be reaction [PDF]

EPJ Web of Conferences, 2022
The 6Li(p,γ)7Be reaction is involved in all three main nucleosynthesis scenarios: Big Bang Nucleosynthesis, the interaction of cosmic rays with interstellar matter, and stellar nucleosynthesis.

Constraints on Axion-Lepton coupling from Big Bang Nucleosynthesis [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
In this article, we study the implications of the coupling between Axion-Like-Particles (ALPs) and Leptons to cosmology in particular, the Big Bang Nucleosynthesis (BBN) .

Consequences of neutrino self-interactions for weak decoupling and big bang nucleosynthesis [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
We calculate and discuss the implications of neutrino self-interactions for the physics of weak decoupling and big bang nucleosynthesis (BBN) in the early universe.

THE ²H(alpha, gamma)⁶LI REACTION AT LUNA AND BIG BANG NUCLEOSYNTHETIS

Acta Polytechnica, 2013
The 2H(α, γ)6Li reaction is the leading process for the production of 6Li in standard Big Bang Nucleosynthesis. Recent observations of lithium abundance in metal-poor halo stars suggest that there might be a 6Li plateau, similar to the well-known Spite ...

Does the CMB prefer a leptonic Universe?

New Journal of Physics, 2013
Recent observations of the cosmic microwave background at smallest angular scales and updated abundances of primordial elements indicate an increase of the energy density and the helium-4 abundance with respect to standard big bang nucleosynthesis with ...

Lorentz invariance violation in the neutrino sector: a joint analysis from big bang nucleosynthesis and the cosmic microwave background

European Physical Journal C: Particles and Fields, 2017
We investigate constraints on Lorentz invariance violation in the neutrino sector from a joint analysis of big bang nucleosynthesis and the cosmic microwave background.

Experimental studies on astrophysical reactions at the low-energy RI beam separator CRIB [PDF]

EPJ Web of Conferences, 2022
Experimental studies on astrophysical reactions involving radioactive isotopes (RI) often accompany technical challenges. Studies on such nuclear reactions have been conducted at the low-energy RI beam separator CRIB, operated by Center for Nuclear Study,

Neutrinos and Big Bang Nucleosynthesis

Advances in High Energy Physics, 2012
According to the standard models of particle physics and cosmology, there should be a background of cosmic neutrinos in the present Universe, similar to the cosmic microwave photon background.

Big bang nucleosynthesis: Present status [PDF]

, 2015
Big-bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a dynamic interplay among the four fundamental forces during the first seconds of cosmic time.
