论文摘要
我们展示了如何将重拷贝重夸克有效理论（HQET）与旋转$ S \ leq 1 $的重黑洞有效理论（HBET）。特别是，带有标量QCD的Spin-$ S $ HQET的双副本可产生旋转$ S $ HBET，而带有Spin-1/2 HQET的双副本与Spin-1/2 HQET本身可提供Spin-1 HBET。最后，我们提出了用于自旋1重粒子的新型全阶质量拉格朗日。
We show how to double-copy Heavy Quark Effective Theory (HQET) to Heavy Black Hole Effective Theory (HBET) for spin $s\leq 1$. In particular, the double copy of spin-$s$ HQET with scalar QCD produces spin-$s$ HBET, while the double copy of spin-1/2 HQET with itself gives spin-1 HBET. Finally, we present novel all-order-in-mass Lagrangians for spin-1 heavy particles.
