Query: About the fine-tuning price of LEP   Following Chankowski, Ellis and Pokorski we quantify the amount of
fine-tuning of input parameters of the Minimal Supersymmetric Standard Model
that is needed to respect the lower limits on sparticle and Higgs masses
imposed by negative searches so far, direct or indirect. By including the one
loop radiative corrections to the effective potential, the amount of
fine-tuning is reduced with respect to the results of CEP by a factor of 2--5,
strongly increasing as tan\beta approaches 1. A further reduction factor may
come from a more appropriate, less restrictive, definition of the fine-tuning
parameter itself.
