标题： Least-Order Torsion-Gravity for Chiral-Spinor Fields, induced Self-Interacting Potentials and Parity Conservation

摘要： 我们将考虑在充满左手和右手半旋量场的引力背景中，扭转完成的最一般的低阶导数作用量，包括所有宇称偶和宇称奇的贡献；我们将通过进行常规分析，分解扭转并将其用半旋量密度电流表示，从而得到具有扭转诱导的自相互作用势能的有效作用量，这些势能来自手征费米子场之间：我们将看到，最终得到的有效非线性势能将表现出宇称守恒。 显示英文摘要

摘要： We will consider the most general least-order derivative action for the torsional completion of gravitational backgrounds filled with left-handed and right-handed semi-spinorial fields, accounting for all parity-even as well as parity-odd contributions; we will proceed by performing the customary analysis, decomposing torsion and substituting it in terms of the semi-spinorial density currents, in order to obtain the effective action with the torsionally-induced self-interacting potentials among the chiral fermionic fields: we shall see that the resulting effective non-linear potentials will turn eventually out to be parity conserving after all.
