论文摘要

磁性极化性是Hadron的基本特性,它可以深入了解其在低能量状态下的结构。在存在背景磁场的情况下,使用晶状体QCD计算锥度磁极性。提出的结果通过引入新的磁场Quark-propagator eigenmode投影仪,并使用背景场​​校正的三叶草费米昂的动作来促进。磁极化能力是在相对论形式主义中计算的,而Pion相关功能的出色信号到噪声特性有助于精确值。

The magnetic polarisability is a fundamental property of hadrons, which provides insight into their structure in the low-energy regime. The pion magnetic polarisability is calculated using lattice QCD in the presence of background magnetic fields. The results presented are facilitated by the introduction of a new magnetic-field dependent quark-propagator eigenmode projector and the use of the background-field corrected clover fermion action. The magnetic polarisabilities are calculated in a relativistic formalism, and the excellent signal-to-noise property of pion correlation functions facilitates precise values.
