Summary
To describe the ρ0 and ω photoproductions we propose the pseudomodel in which the quark model of photoproduction is supplemented with the well-established observations that the pomeron contributions are dominant in the ρ0 photoproduction and that the one-pion exchange as well as the pomeron are important contributors in the ω photoproduction. We derive a number of relations as well as inequalities between ρ0 and ω photoproductions. We show that these relations are in overall satisfactory agreement with the available data.
Riassunto
Per descrivere le fotoproduzioni di ρ0 e ω si propone uno pseudomodello in cui il modello a quark della fotoproduzione è integrato con le ben accertate osservazioni che i contributi del pomerone sono predominanti nella fotoproduzione di ρ0 e che sia lo scambio di un pione che il pomerone sono contributi importanti nella fotoproduzione di ω. Si deriva un certo numero di relazioni e di disuguaglianze fra le fotoproduzioni di ρ0 e ω. Si mostra che queste relazioni sono complessivamente in soddisfacente accordo con i dati disponibili.
Реэюме
Для описания процессов фоторождения ρ0 и /gw мы предлагаем псевдомодель, в которой кварковая модель фоторождения дополняется точно установленными реэультатами, что вклады Померoна доминируют в процессе ρ0 фоторождения и что однопионный обмен, а также Померон дают важные вклады в процесс со фоторождения. Мы выводим ряд соотнощений и неравенств между процессами фоторождения ρ0 и ω. Мы покаэываем, что зти соотнощения удовлетворительно согласуются с имеюшимися данными.
