Corrigendum to “Isoscalar single-pion production in the region of Roper and d?(2380) resonances” [Phys. Lett. B 774 (2017) 599]

摘要

In a reinvestigation of the nucleon-nucleon initiated isoscalar single-pion production we noted that the upper limits for the decay of the dibaryon resonance d ? ( 2380 ) into the isoscalar ( NN π ) I = 0 channel via the routes d ? ( 2380 ) → D 12 π → ( NN π ) I = 0 and d ? ( 2380 ) → N ? ( 1440 ) N → ( NN π ) I = 0 are a factor of two smaller than given in Ref. [1]. The reason is that the isoscalar single-pion production cross section σ 0 derived in Ref. [1] by the relation [1–3].
