Summary
We discuss the process γ+p→△++(1236)+π− at low energies by taking into account the gauge-invariant extended OPE contribution and a small admixture of isobaric contributions. We obtain reasonable agreement with recent experimental data from the Aachen-Berlin-Bonn-Hamburg-Heidelberg-München collaboration.
Riassunto
Si discute il processo γ+p→△++(1236)+π− a basse energie tenendo conto del contributo dell’OPE esteso invariante di gauge e una piccola mescolanza di contributi isobarici. Si ottiene un ragionevole accordo con i recenti dati sperimentali della collaborazione Aachen-Bonn-Amburgo-Heidelberg-München.
Резюме
Мы рассматриваем процесс γ+p→△++(1236)+π− при низких щнергиях, принимая во внимание калибровочно инвариантный расширенный OPE-вклад и небольшие примеси изобарических вкладов. Мы получаем разумное согласие с недавними щкспериментальными данными из сотрудничества Аахен-Берлин-Бонн-Гамбург-Гейдельберг-Мюнхен.

The dependence of the gauge-invariant OPE contribution on the γ-polarization has been calculated byK. Böckmann, W. Sandhas andH. Wessel:Zeits. f. Phys.,202, 477 (1967). Compare alsoD. S. Beder andP. Söding: UCRL-17867. In this paper the additional effect of resonances has been included, but the OPE part is treated insufficiently according to our opinion.
