近日，英国帝国理工学院的C. M. Hull及其研究团队取得一项新进展。经过不不懈努力，他们对引力子的磁荷进行了研究。相关研究成果已于2024年5月23日在国际知名学术期刊《高能物理杂志》上发表。

该研究团队研究了线性化引力及其对偶引子场的对偶公式的对称性和守恒电荷。对偶引力子理论构造了守恒电荷，它们与对偶引力子理论的不变性有关。这些不变性产生于某些广义基灵张量的规范参数。

通过此方法，研究者们发现了一种磁型引力电荷，它是d≥5维引力电荷的线性化形式，它在超对称代数中作为中心电荷出现，并由kaluza-klein单极子所携带。此外，研人员还探讨了具有磁性引力电荷的线性化引力解，并分析了这一方法在其他规范理论中的潜在应用。

Abstract: Symmetries and conserved charges are investigated for linearised gravity and its dual formulation in terms of the dual graviton field. Conserved charges are constructed for the dual graviton theory that are associated with invariances of the dual graviton theory. These invariances arise for gauge parameters that are certain generalised Killing tensors. These electric-type charges for the dual graviton are then shown to give magnetic-type charges for the graviton. One of the magnetic-type gravitational charges obtained in this way is the linearisation of the gravitational charge in d ≥ 5 dimensions that arises as a central charge in the supersymmetry algebra and is carried by Kaluza-Klein monopoles. Solutions of linearised gravity carrying the magnetic gravitational charges are discussed. The application of the approach used here to other gauge theories is discussed.
