If sterile neutrinos exist, they are typically considered to be electrically neutral particles that do not interact via the electromagnetic force. Sterile neutrinos are hypothetical particles that are not part of the three known generations of neutrinos in the Standard Model of particle physics.
In the Standard Model, each neutrino flavor (electron neutrino, muon neutrino, and tau neutrino) is associated with a corresponding charged lepton (electron, muon, and tau). These neutrinos participate in weak interactions and are involved in various processes.
If sterile neutrinos exist, they would be separate from the known neutrinos and would not have a direct corresponding charged lepton in the Standard Model. Sterile neutrinos would not interact via the weak force and would be "sterile" in the sense that they do not participate in the known weak interactions.
However, it's important to note that the existence and properties of sterile neutrinos are still under investigation and not yet confirmed. Various experiments and observations are being conducted to search for evidence of sterile neutrinos and explore their potential implications for particle physics and cosmology.
