| Production of orbitally excited D mesons in Aleph |
| P. Colas |
Abstract: ========= From nearly 4 millions Z decays recorded in the ALEPH detector, measurements of the production of excited charmed states are performed. The known narrow L=1 states are searched for in charm hadronization and in b semileptonic decays separately. In addition, in the case of b semileptonic decays, a topological analysis shows evidence for production of both narrow and wide states. |
