Strong Coupling and Classicalization

Dvali, Gia (2017): Strong Coupling and Classicalization. In: Future of Our Physics including New Frontiers, Bd. 53

Abstract

Classicalization is a phenomenon by which a theory shields itself from the strong coupling regime by redistributing a high energy of few initial hard quanta among many weakly-interacting soft quanta. In this way, the high-energy scattering process splits into large number of soft elementary processes, each with very low momentum exchange. The outcome of such a scattering experiment is a production of states of large occupation number that are approximately classical. It is evident that black hole creation in particle collision at super-Planckian energies is a result of classicalization, but there is no a priory reason why this phenomenon must be limited to gravity. If the hierarchy problem is solved by classicalization, the LHC has a chance of detecting the tower of resonances. The heavier resonances are expected to be longer-lived and to decay into larger number of the softer quanta.
