pp -> dpi+ pi0的独家测量：无ABC效应的双粒子融合
Exclusive Measurements of pp -> dpi+pi0: Double-Pionic Fusion without ABC Effect
摘要：
在T_p = 1.1GeV的CELSIUS储存环上，用WASA探测器对pp -> dpi+ pi_0反应进行了独家测量。等矢量pi+ pi 0通道在低不变pipi质量下不表现出增强，即。e.无ABC效应。微分分布与传统的t-通道三角洲-三角洲激发过程，这也占所观察到的总截面的能量依赖性是一致的。这是对以前发布的版本的更新--请参阅文章末尾的重要说明。
英文摘要：
Exclusive measurements of the reaction pp -> dpi+pi0 have been carried out at T_p = 1.1 GeV at the CELSIUS storage ring using the WASA detector. The isovector pi+pi0 channel exhibits no enhancement at low invariant pipi masses, i. e. no ABC effect. The differential distributions are in agreement with the conventional t-channel Delta-Delta excitation process, which also accounts for the observed energy dependence of the total cross section. This is an update of a previously published version -- see important note at the end of the article.
