Query: Classicalization in Derivatively Coupled Scalar Field Theories: A
  Feasibility Study   It has been suggested that a certain class of UV-incomplete quantum field
theories can avoid unitarity violation above the cut-off energy scale by
forming classical configurations at a length scale much larger than the cut-off
length. This phenomenon has been named classicalization and is characterized by
a length scale called classicalization radius $r_*$ which increases with
energy. It has been argued that scalar field theories with derivative
self-interactions are likely candidate for UV-completetion by classicalization
and are much likely to form classicalons compared to non-classicalizing
theories like $\phi^4$ scalar field theory. To look further into this claim, in
this paper 2 to N particle scattering amplitude, scattering cross-section and
the amplitude of classical structure formation has been calculated and compared
for a classicalizing and non-classicalizing theory. As the phenomenon of
classicalization relies on creating a large number of low energy particles from
high energy two particle scattering, the ratios between the scattering
amplitudes and the amplitude of classical structure formation in these two
cases are an indicator of the feasibility of the classicalization process. From
our calculation, it has been observed that with the increase of energy, the
ratios of the relevant quantities between classicalizing and non-classicalizing
theory actually decrease which is quite contrary to the expected behaviour if
classicalization is supposed to self-unitarize certain class of theories beyond
cut-off energy.
