    "abstract": "It is shown that the true parameters of He-4-Sigma differ from the observed\nones. The reason is that the amplitude of He-4-Sigma production in the reaction\nHe-4(K-,pi-) sharply varies just in the corresponding mass region. It leads to\nthe small, but noticeable shift of the binding energy and the width. Besides,\nthe data at the threshold of Sigma-0 production is found to give an additional\nevidence that He-4-Sigma width cannot exceed 8.0 - 8.5 MeV.",
