摘要： 中子的静态电极化率使用MILC asqtad海夸克集合上的域墙价夸克进行评估，对应的π介子质量为m_pi = 357 MeV。 包含了连接和非连接贡献。 结果在定量上与手征有效理论的预期相符。 显示英文摘要

摘要： The static electric polarizability of the neutron is evaluated using domain-wall valence quarks on a MILC asqtad sea quark ensemble corresponding to a pion mass of m_pi = 357 MeV. Both connected as well as disconnected contributions are included. The result is quantitatively compatible with the expectation from chiral effective theory.
