Gravitational dressing, soft charges, and perturbative gravitational splitting
In gauge theories and gravity, field variables are generally not gauge-invariant observables, but such observables may be constructed by “dressing” these or more general operators. Dressed operators create particles, together with their gauge or gravitational fields which typically extend to infinit...
