To the problem on the quark content of delta(980) meson
Description
Within the framework of the nonlocal quark model the width of eta' → etaππ decay due to the intermediate delta (980) meson (eta' → deltaπ → etaππ) is calculated on the assumption that delta meson consists of either two-quark or four-quark system. The result obtained in the two-quark case agrees with the experimetnal data but the calculated value of the decay width in the four-quark case is larger approximately by 50 times than the experimental one
