摘要

在相关函数框架内重新研究了耦合通道方案中矢量介子-重子相互作用。作为揭示耦合通道所起重要作用的说明性案例，我们关注于考虑到它们的复杂动力学以及在它们的阈值附近存在准束缚状态或共振的ϕp和ρ0p系统。我们表明，在实验区域中，通过使用波束数据提供了关于N*态的新信息，并预测了未来ρ0p相关函数测量的相关性，从而确定S=0，Q=+1矢量介子-重子相互作用，并揭示了N*(1700)态的特征。2025年由美国物理学会出版

Relevance of the coupled channels in the ϕp and ρ0p correlation functions

The vector meson-baryon interaction in a coupled channel scheme is revisited within the correlation function framework. As illustrative cases to reveal the important role played by the coupled channels, we focus on the ϕp and ρ0p systems given their complex dynamics and the presence of quasibound states or resonances in the vicinity of their thresholds. We show that the ϕp femtoscopic data provide novel information about a N* state present in the experimental region and anticipate the relevance of a future ρ0p correlation function measurement in order to pin down the S=0,Q=+1 vector meson-baryon interaction as well as to disclose the characterizing features of the N*(1700) state.
