8. Ab initio prediction of α(d,γ)6Li at Big Bang nucleosynthesis energies

Chloë Hebborn (Facility for Rare Isotope Beam (MSU) and Lawrence Livermore National Lab)

Invited Talk

The radiative capture α(d,γ)6Li is the dominant process in the Big Bang Nucleosynthesis (BBN) of 6Li. It therefore strongly influences the abundance ratio of 6Li/7Li, for which observational data are three orders of magnitude higher than BBN predictions. Because of the low cross section and the large experimental uncertainties, it is crucial to have accurate predictions. In this talk, I will...

136. Neutrinoless double beta decay in effective field theory

Wouter Dekens (Institute for Nuclear Theory)

Invited Talk

Neutrinoless double beta decay (NLDBD) is the most sensitive probe of lepton-number violation. Its discovery would be a clear signal of physics beyond the Standard Model, confirm the Majorana nature of neutrinos, and provide insight into scenarios of baryogenesis through leptogenesis. In this talk, I will show how the calculation of the decay rate can be organized in a systematic way using...

24. From Few to Many: Recent Advances in Ab Initio Nuclear Structure Calculations

Dr Alexander Tichai (TU Darmstadt)

02/08/2023, 12:25

Invited Talk

A first-principle description of atomic nuclei requires the use of two- and three-nucleon interactions combined with an efficient many-body solution for the nuclear state. In particular the treatment of chiral three-body operators provides a significant computational challenge due to high memory requirements. In the first part of my talk, I will discuss two complementary ways to cope with that...
