Description
We extend the eV seesaw scenario to four lepton generations. The
LSND anomaly is taken as the right-handed seesaw scale, i.e. m_R
~ eV. The fourth generation then gives a heavy pseudo-Dirac
neutrino which largely decouples from other generations, and is
relatively stable. One effectively has a 3+3 solution to the
LSND anomaly, where we illustrate with numerical solutions. Our
study indicates that the third mixing angle sin^2(theta_13)
is likely less than 0.01
