Hypertriton极化率

Hypertriton Electric Polarizability

V. F. Kharchenko, A. V. Kharchenko

摘要:

本文给出了一种严格的形式,用以确定只有一个束缚(基态)态的三强子束缚复合体的电偶极极化率。在此基础上,采用考虑最轻超核结构特征的模型波函数,以已知的p-n和p-d系统的低能实验数据为输入,计算了λ超夸克的电偶极极化率。从我们的研究可以得出,λ超夸克的极化率接近3 fm^3,比普通的三核子核的极化率高出一个数量级。

英文摘要:

A rigorous formalism for determining the electric dipole polarizability of a three-hadron bound complex in the case that the system has only one bound (ground) state has been elaborated. On its basis, by applying a model wave function that takes into account specific features of the structure of the lightest hypernucleus and using the known low-energy experimental data for the p-n and lambda-d systems as input data, we have calculated the value of the electric dipole polarizability of the lambda hypertriton. It follows from our study that the polarizability of the lambda hypertriton is close to 3 fm^3 exceeding the polarizabilities of the ordinary three-nucleon nuclei by an order of magnitude.
