Relating Gauge and Gravity Theories in the Large Mass Limit
Kays Haddad, Andreas Helset
Abstract
We show how to double copy heavy quark effective theory (HQET) to heavy black hole effective theory (HBET) for spin s≤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.
