This effect influences the active-sterile neutrino mixing and provides a possibility to accommodate the LSND evidence for neutrino oscillations together with bounds from accelerator and reactor experiments. We briefly comment on causality in such schemes.4 pages, 3 figures, talk presented by H. Paes at SUSY06, UC Irvine, CAHigh Energy Physics - Phenomenologytext
