Description

Investigations of neutral finale states in pion-nucleon interactions are carried out. Spectra and characteristics of resonances in these interactions are defined for the following comparison with quark models. On the measurement results of differential cross sections of π-p → π0n and π-p → ηn. The threshold effects are studied in the range of η-mesons (685 MeV/c) threshold production

Abstract (Russian)

Проведены исследования нейтральных конечных состояний в пион-нуклонных взаимодействиях. Определены спектры и характеристики резонансов пион-нуклонных взаимодействий для последующего сравнения с кварковыми моделями. По измерению дифференциальных сечений π-p → π0n и π-p → ηn изучаются пороговые эффекты в области порогообразования η-мезонов (685 МэВ/с)
