Sujet:	Excited Beauty - more than just spectroscopy

Par:	Dr. Robert Kowalewski, universite de Geneve

Resume:	The discovery of strongly decaying B hadrons, the so-called 
	$B^{**},$ will be reviewed and the present status of the 
	measurements summarized.  The $B^{**}$ system allows tests
	of Heavy Quark Effective Theory.  In addition, these states,
	and more generally correlations between the b quantum number
	of a hadron and the charges of pions produced in the
	fragmentation process, may play an important role in flavor
	tagging for measurements of CP violation in the B sector.
