spectroscopy of exotic atoms

Oral presentation

Muonium (Mu = $\mu^+ + e^-$) is a purely leptonic, two-body exotic atom amenable to laser spectroscopy, which provides precision measurements of fundamental constants ($m_\mu, \mu_\mu$), and tests of bound state QED. It also provides a unique probe to test the weak equivalence principle on elementary antimatter of the second generation using a system without large contributions to the mass...

90. Electroweak nuclear radii constrain isospin-breaking corrections to $V_{ud}$

tests and extensions of the Standard Model of elementary particles

Oral presentation

The most precise determination of the top-left corner element of the CKM quark mixing matrix $V_{ud}$ is obtained from accurate measurements of superallowed nuclear $\beta$ decays. Among the theoretical ingredients in this determination, the isospin symmetry-breaking (ISB) correction $\delta_\mathrm{C}$ plays a crucial role in aligning the $Ft$-values across all superallowed transitions. This...
