Flavour-Changing Weak Interactions of Neutrinos and Quarks from SST

According to the Scale-Symmetric Theory (SST), there is a similarity of shapes and equality of mass ratios of the components of the three basic cores, i.e. of the core of lightest neutrinos, charged core of baryons, and the core of the Protoworld that was composed of dark matter. From the neutrino-spin rotation, we calculated the masses of the cosmological neutrinos. Two characteristic neutrino oscillations lead to $\Delta m_{32,mean}^2=2.45\times {10}^{？3}\text{？}{\text{eV}}^2$ and $\Delta m_{21,mean}^2=7.42\times {10}^{？5}\text{？}{\text{eV}}^2$ . The ${\nu }_e？{\nu }_{\mu }$ transitions are possible only via the tau-neutrino. We also described three neutrino oscillation anomalies that follow from $\Delta m_{41,mean}^2=1.32\times {10}^{？2}\text{？}{\text{eV}}^2$ , $\Delta m_{41,mean}^2=1.36\text{？}{\text{eV}}^2$ , and $$
