摘要

研究考虑了超引力通量背景下狄拉克算子的修正。针对不同类型的通量修正，得到了与薛定谔-李奇诺维茨类似公式相对应的修正自旋曲率算子和修正狄拉克算子的平方。用修正的基林-雅诺形式和修正的共形基林-雅诺形式找到了修正的无质量和大质量狄拉克方程的对称算子。根据不同类型的通量和修正的基林-雅诺形式确定了对称算子的额外约束。

Symmetries of modified Dirac operators in supergravity flux backgrounds

Modifications of Dirac operators in supergravity flux backgrounds are considered. Modified spin curvature operators and squares of modified Dirac operators corresponding to Schrödinger-Lichnerowicz-like formulas are obtained for different types of flux modifications. Symmetry operators of modified massless and massive Dirac equations are found in terms of modified Killing-Yano and modified conformal Killing-Yano forms. Extra constraints for symmetry operators in terms of different types of fluxes and modified Killing-Yano forms are determined.

期刊介绍： Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
