Abstract
A generalized slave-particle scheme is introduced to the t-J model inc luding the non-local effects. We find a charge-spin decoupled state in which the non-local gauge fields play the roles of statistics-transmu tation. As a result, the gauge fluctuation becomes massive and the ele ctromagnetic response function exhibits the Meissner effect, like in t he free-semion system, but without breaking the time-reversal and pari ty symmetries due to the cancellation between charge and spin degrees of freedom.
