Measurement of the Λc charmed baryon production and the study of the Λc baryon semi-leptonic decays by the DELPHI experiment at LEP
Description
By using the data accumulated in the DELPHI experiment from 1992 to 1994 we present the results of the production rate measurement of Λc charmed baryons generated in the bb-bar and cc-bar events. For these measurements we reconstructed entirely the Λc baryons decaying in pKπ. Then we select a set of bottom baryons Λb0 by means of its semi-leptonic decays in Λc+l-νl-bar. The study of distribution of these events as a function of the transfer momentum allowed estimating for the first time the slope of the Λb0 form factor. (author)
