Search for a fourth generation b'-quark at LEP-II
In this thesis, a search for the pair production of sequential fourth generation quarks at LEP ($e^+ e^-\to b'\bar{b'}$) is presented. The data collected by DELPHI at centre-of-mass energies ranging from 196 GeV to 209~GeV, corresponding to an integrated luminosity of about 420~pb$^{-1}$,...
