Deuterium burning measurement at LUNA and its astrophysical and nuclear implications

The D(p,gamma)He-3 reaction is responsible for the deuterium destruction during the Big Bang Nucleosynthesis (BBN) and affects the primordial deuterium abundance. This latter is sensitive to fundamental cosmological parameters such as the baryon density and the effective number of relativistic species. In this paper, we describe the most precise direct measurement of the D(p,gamma)He-3 reaction in the BBN energy range (E-cm = 30-280 keV) at the LUNA (Laboratory for Underground results, cosmological consequences, and future prospects are reported here.
