Abstract
A two-dimensional (2D) assembly of noninteracting, temperature-dependent, pre-formed Cooper pairs in chemical/thermal equilibrium with unpaired fermions is examined in a binary boson-fermion statistical model as the Bose-Einstein condensation (BEC) singularity temperature is approached from above. Compared with BCS theory (which is {\it not} a BEC theory) substantially higher 's are obtained without any adjustable parameters, that fall roughly within the range of empirical 's for quasi-2D cuprate superconductors.
