چکیده
A theoretical treatment for the weak decays of heavy-flavour hadrons has been developed that is genuinely based on QCD. Its methodology as it applies to total lifetimes and the underlying theoretical issues are sketched. Predictions are compared with present data. One discrepancy emerges: the beauty baryon lifetime appears to be significantly shorter than expected. The ramifications of those findings are analyzed in detail.

متن کاملNot Poles Apart : " Whither Reform ? " and " Whence Reform ?
The paper "Whence Reform?" by the Polish economists Marek Dabrowski, Stanislaw Gomulka, and Jacek Rostowski (DGR) is a welcome and revealing commentary on what is called the "Stiglitz Perspective." Our main response is gratitude at DGR's agreement with the main theses of "Whither Reform?" such as the critiques of voucher privatization and of the attempts to quickly install institutional reforms...
