In this article, the study of asymptotic gravitational charges is discussed, with a focus on higher derivative charges. The authors find a connection between higher derivative Bondi-Metzner-Sachs (BMS) charges and two-derivative BMS charges. It is noted that internal Lorentz transformations are relevant in the higher derivative case unlike the two-derivative case. The article provides a prescription for the precise definition of these charges and derives the associated charges, once again establishing a relationship with two-derivative BMS charges.
In line with a recent proposal for the study of asymptotic gravitational charges, we investigate higher derivative asymptotic charges. We show that the higher derivative Bondi-Metzner-Sachs (BMS) charges are related to the two-derivative BMS charges. Significantly, we find that internal Lorentz transformations are relevant in the higher derivative case in contrast to the two-derivative case. We give a prescription for their precise definition and derive the associated charges, finding, again, a relation with two-derivative BMS charges.
