Abstract
The divergences of the generating functional of quenched Chiral Pertur bation theory (qCHPT) to one loop are computed in closed form. We show how the quenched chiral logarithms can be reabsorbed in the renormali zation of the B-0 parameter of the leading order Lagrangian. Finally, we do the chiral power counting for the quenched case and show that al so finite loop corrections may diverge in the chiral limit.
