Abstract

The behavior of the annihilation rate of positrons in a strongly correlated two-dimensional electron system in which the spin and charge degrees of freedom are decoupled is examined, and it is found that the positron lifetime becomes longer in the proposed resonating-valence-bond paired-boson superconductor when a gap exists for the charged excitations.
