Quantum Hair During Gravitational Collapse (published version in Physical Review D)

This is a follow up to our earlier work on quantum gravitational corrections to the exterior graviton field of a compact object, also known as quantum hair. 

Here we follow the gravitational collapse of a dust ball and show that the quantum hair persists through the formation of a black hole horizon. The detailed calculations are possible due to an effective field theory formulation of quantum gravity in the long wavelength, low spacetime curvature limit.
