Classicalization of Gravitons and Goldstones

Understand

We establish a close parallel between classicalization of gravitons and derivatively-coupled Nambu-Goldstone-type scalars.

• We show, that black hole formation in high energy scattering process represents classicalization with the classicalization radius given by Schwarzschild radius of center of mass energy, and with the precursor of black hole entropy being given by number of soft quanta composing this classical configuration.
• Such an entropy-equivalent is defined for scalar classicalons also and is responsible for exponential suppression of their decay into small number of final particles.
• This parallel works in both ways.
