- Sabin Stoica (CIFRA)
The low-energy QCD, the theory within the Standard Model describing the strong interaction, is still missing fundamental experimental results to achieve a breakthrough in its understanding. Among these, the low-energy kaon-nucleon/nuclei interaction studies are playing a key-role.
Combining the excellent quality of the low-energy kaon beam delivered by the DANE collider of INFN-LNF with new...
In my talk I will highlight the background and achievements, as also some prospects, of the NEPTUN (NEutrino Properties Through Use of Nuclei) project's first year. NEPTUN is a 3-year neutrino-related nuclear-physics project funded by the EU through the Romanian Ministry of Research, Innovation and Digitzation. I will discuss the problem of the effective value of the weak axial-vector coupling...
We reexamine one of the most promising candidates for determining the neutrino mass scale: the unique first forbidden $\beta$ transition from $^{187}$Re($5/2^+$) to $^{187}$Os($1/2^-$). With the lowest-known ground-state to ground-state $Q$-value for a $\beta$ transition at $2.4709$ keV, rhenium's $\beta$ decay can offer insights into the neutrino mass scale puzzle. However, understanding its...
We present the normalized distributions of released energy in electron capture (EC) decay as a method for determining the neutrino mass. Our calculations account for exchange and overlap corrections, shake-up and shake-off atomic effects, electron screening effects, and the intrinsic line-widths of Breit-Wigner resonances.
The wave functions of the electrons were computed using the...
