在低能有效场论的框架内,从现有的K介子氢和合成氘数据的综合分析中提取了S波K介子-核子散射长度a(0)和a(1)。结果表明,在目前的DEAR中心值的K介子氢基态能量和宽度,a(0)和a(1)的解决方案只存在于一个有限的域的输入值的K介子-氘核散射长度。因此,测量这种散射长度施加严格的约束,在低能量的K介子-氘核相互作用的理论描述,如果补充DEAR数据K介子氢。
The extraction of the S-wave kaon-nucleon scattering lengths a(0) and a(1) from a combined analysis of existing kaonic hydrogen and synthetic deuterium data has been carried out within the framework of a low-energy effective field theory. It turns out that with the present DEAR central values for the kaonic hydrogen ground-state energy and width, a solution for a(0) and a(1) exists only in a restricted domain of input values for the kaon-deuteron scattering length. Consequently, measuring this scattering length imposes stringent constraints on the theoretical description of the kaon-deuteron interactions at low energies, if supplemented with DEAR data on kaonic hydrogen.
