Study of $B^{0}\to K^{0}\gamma $ with conversions and $B^{0}\to K^{0}e+e-$ at very low $q^2$

Lepton Flavour Universality is a property of the Standard Model. In recent years, several anomalies have been observed by LHCb in rare flavour changing neutral current decays of $B$ hadrons characterized by $b\rightarrow s\ell\ell$ transition, where $\ell$ stands for electrons or muons final states....
