Further Analysis of D⁰ Meson in the Reaction pi ⁺po ppi ⁺pi ⁺pi ⁺pi ^-pi ^-pi ⁰ at 8 GeV/c

摘要

The existence of the intermediate delta pi state in the decay D⁰ o eta pi pi is discussed. It is shown that the reflection of the omega production cannot produce a spurious maximum in the (eta pi ) mass distribution at the position of the delta .
