13. On the correlation between the isospin-symmetry breaking correction and $E0$-transition strengths in superallowed $0^+\rightarrow0^+$ nuclear $\beta$ decay

Oral Presentation

We investigate the correlation between the isospin-symmetry breaking correction to superallowed $0^+\rightarrow0^+$ nuclear $\beta$ decay of isotriplets and the $E0$-transition strength between the isobaric analog and the first excited $0^+$ states in the $T_z=1$ nuclei. Specifically, the correction, as obtained within the shell-model approach, is suppressed where the experimental $E0$...

19. Matter's origin from the radioactivity of trapped ions

Oral Presentation

Everything we observe in the universe is thanks to interactions of particles and antiparticles, from subatomic processes to the formation of galaxies since the Big Bang. But regardless of where we look, we do not see macroscopic quantities of antimatter in nature, only in quantum interactions or produced by us in laboratories. With our current understanding of physics, when matter originated...

29. Fermi beta decay of $^{10}C$ measured with AGATA: constraints on $V_{ud}$

Oral Presentation

The Cabibbo-Kobayashi-Maskawa (CKM) matrix describes the weak charged-current interactions of quarks within the framework of the Standard Model of particle physics. It governs, in particular, $\beta$ decays through coupling with the $W^{\pm}$ bosons. To test its validity, the terms of the CKM matrix must be determined with high precision, and their uncertainties must be well understood. One of...

17. Nuclear moments and mean-squared charge radii of neutron deficient rhodium isotopes measured using collinear laser spectroscopy

Saikumar Chinthakayala (University of Caen / GANIL)

Oral Presentation

The region between the strongly deformed nuclei around the $Z \sim 40$, $N \sim 60$ mass region and the spherical Sn chain represents a rich testing ground for nuclear structure models, probing shell evolution and the interplay between single-particle and collective degrees of freedom, as well as phenomena such as shape coexistence. In this context nuclear magnetic dipole moments are sensitive...

52. Testing the Standard Model with the WISArD experiment

Samuel Lecanuet

Oral Presentation

The WISArD experiment is a high precision measurement of nuclear beta decay observables to test the existence of Physics Beyond the Standard Model in the weak sector. The angular correlation parameter $a_{\beta\nu}$ and the Fierz interference term $b$ in particular, are very sensitive probes to the existence of exotic scalar or tensor currents, which are not included in the standard V-A theory...
