A new analysis of the "hep" S-factor and the "hen" cross section

Michele Viviani, Alex Gnech, Laura Elisa Marcucci +2

We present a new accurate analysis of the HeHe (''hep'') reaction at astrophysical energies. The S-factor is computed using a state-of-the-art method to calc…

Bayesian analysis of proton-proton fusion in chiral effective field theory

Vittorio Barlucchi, Alex Gnech, Scilla Degl'Innocenti +1

The astrophysical -factor for the proton-proton fusion is calculated in the low-energy regime for a variety of nuclear interactions and consistent nuclear currents, derived with…

ToMCCA-3: A realistic 3-body coalescence model

Maximilian Mahlein, Bhawani Singh, Michele Viviani +4

The formation of light nuclei in high-energy collisions provides valuable insights into the underlying dynamics of the strong interaction and the structure of the particle-emitting…

nuclear contact coefficients in the generalized contact formalism

E. Proietti, L. E. Marcucci, M. Viviani

We present a theoretical calculation for the and 4 nuclear contact coefficients within the generalized contact formalism, using both local and non-local chiral potential…

Nuclear Physics Mid Term Plan at LNGS

R. Buompane, F. Cavanna, C. Curceanu +59

The Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Gran Sasso (LNGS) is one of the largest underground physics laboratory, a very peculiar environment suited for ex…

Emulation of Proton-Deuteron Scattering via the Reduced Basis Method and Active Learning: Detailed Description

Alex Gnech, Xilin Zhang, Christian Drischler +5

Nucleon-deuteron () scattering can be used to constrain three-nucleon forces in chiral effective field theory (EFT). However, high-fidelity calculations, such as the Hypers…
