The implications of the final L3 measurement of $\sigma_{tot}(\gamma\gamma\to b\bar{b}$
The excess of data on the total cross section of $\bar{b}b$ production in $\gamma\gamma$ collisions over QCD predictions, observed by L3, OPAL and DELPHI Collaborations at LEP2, has so far defied explanation. The recent final analysis of L3 data has brought important new information concerning the d...
