K0 s and a production in quark and gluon jets at LEP

A measurement of the K(SJ and A inclusive production rates and momentum spectra in twoand three-jet events is presented. On the basis of about 3. J million Z decays collected with the L3 detector at LEP, we observe that the production of these particles is well modelled by string fragmentation. © 1997 Elsevier Science B.V.
