Consider classically two concentric spherical thin mass shells. The inner one is negative mass, the outer one is positive mass. Seems to me that is unstable - it explodes. The outer shell of positive mass would be a model for the cloud of virtual particles.'

Of course adding the Bohm quantum potential may stabilize it?

Indeed, Deser's 1960 model you cite makes more physical sense in my opinion.

I never suggested negative mass micro-black holes. The pomeron vacuum trajectory has a tachyon negative mass squared intercept at J = 0.

Negative mass makes repulsive gravity. A positive-negative mass gravity dipole self-accelerates.

If the micro-black hole has an Unruh temperature at the horizon then the Hawking radiation should explain its decay rate viewed as a hadronic resonance.

Hmmm. . . .  With negative bare mass you don't need f-gravity to get a realistic answer.  Gotta go do some work on the car before it gets dark.  :-)
