Generalized Chou-Yang model (GCYM) predicts electromagnetic form factors of several hadrons with varying magnitude of strangeness. By using these form factors, the root mean square (RMS) radii of the hadrons such as ( π , p , ϕ , Λ , Σ + , Σ − and Ω − )are computed. It is found that there is consistency among the predicted RMS radii of pion and proton by GCYM (and other models) and experimental results. For all hadrons experimental results are not available. Also we find that results of GCYM and from other models are somewhat inconsistent for hadrons other than pion and proton. Though GCYM and other models do not agree for most of the hadrons but they have one similarity that the computed RMS radii seem decreasing with the increase in the strangeness level, separately for mesons as well as for baryons. The experimental results of hadrons other than pion and proton are needed to check the suitability of GCYM and other models as well as in probing the trend of decreasing radii with increase in strangeness content.

广义周阳模型和强子半径

广义周阳模型 (GCYM) 预测了几个具有不同奇异程度的强子的电磁形状因子。通过使用这些形状因子，可以计算强子的均方根 (RMS) 半径，例如 ( π , p , ϕ , Λ , Σ + , Σ − 和 Ω − )。发现GCYM（和其他模型）预测的pion和质子的RMS半径与实验结果之间存在一致性。对于所有强子，实验结果不可用。我们还发现 GCYM 和其他模型的结果对于除 pion 和质子之外的强子有些不一致。尽管 GCYM 和其他模型对大多数强子不同意，但它们有一个相似之处，即计算出的 RMS 半径似乎随着奇异性水平的增加而减小，分别是介子和重子。
