Z-induced FCNCs and their effects on Neutrino Oscillations
نویسندگان
چکیده
Adding singlet neutrinos to the standard model spectrum in general gives rise to Z-induced flavor-changing neutral currents. We study the impact of these currents on matter-induced neutrino oscillations in the sun and in supernovae. While the effects for solar neutrinos are negligible, dramatic effects are possible for supernova neutrinos.

Fcnc Solutions to the Solar Neutrino Problem
In his seminal paper 1 Lincoln Wolfenstein considered flavor changing neutral current (FCNC) effects on neutrino oscillations. He noticed that if the neutrino current in the effective four-fermion interaction Lagrangian has a flavor nonsymmetric part it can significantly affect neutrino oscillations by changing the neutrino indices of refraction in matter. Furthermore, if the neutrinos are mass...

متن کاملMedium effects in string-dilaton-induced neutrino oscillations
We consider the unconventional way to interpret the current data on solar neutrino oscillations as derived recently by Halprin and Leung from a string model based on the existence of the string dilaton field which remains massless in the low-energy world. The equivalence principle violation entailed by the existence of a massless dilaton may then produce neutrino oscillations even for neutrinos...
متن کاملFlavor changing neutrino interactions and CP violation in neutrino oscillations
We investigate the interference effects of non-standard neutrino matter interactions (NSNI) with the mass-induced neutrino oscillations. The NSNI is composed of flavor-changing neutrino interactions (FCNI) and flavor-diagonal neutrino interactions (FDNI). Both of the interactions are introduced in the νμ − ντ sector and the νe−νμ sector in order to study their effects in νμ → ντ and νμ → νe osc...
