Inclusive production of strangenessS=±1 vector and tensor resonances inK−p interactions at 32 GeV/c
European Physical Journal C（1980）
摘要
We present final results on the inclusive production of the
,K*-(890),K*0(890),K*-(890),K*-(1420), and
resonances inK-p interactions at 32 GeV/c. Total cross sections and invariantx-distributions are determined. Inclusive cross sections of
amount to ?4 mb each, of
to ?1 mb and ofK*0(890) to ?0.8 mb. These values are in agreement with additive quark model predictions. All strangenessS=-1 resonances are predominantly produced in the forward hemisphere, the tensor mesons being more peripherally produced than the vector ones. The
density matrix elements andt-distributions are obtained. The unnatural spin-parity exchange contribution to inclusive
production amounts to ?60% at |t|2 and decreases with increasing |t|. Whenever relevant, a comparison is also made with available data at other energies.
