Abstract
The nuclear charge radius of Si was determined using collinear laser spectroscopy. The experimental result was confronted with ab initio nuclear lattice effective field theory, valence-space in-medium similarity renormalization group, and mean field calculations, highlighting important achievements and challenges of modern many-body methods. The charge radius of Si completes the radii of the mirror pair Ar - Si, whose difference was correlated to the slope of the symmetry energy in the nuclear equation of state. Our result suggests \,MeV, which agrees with complementary observables.
