  In quantum field theory, the probability of producing scalar particles grows
factorially as a function of the number of the particles produced. This poses a
problem theoretically, in maintaining unitarity, and is counter-intuitive
phenomenologically. The factorial growth is a byproduct of the perturbation
theory. Nevertheless, it has been recently proposed that the factorial growth
might be observable in the future 100 TeV hadron collider. We collect some of
the calculations that had been done in regards to this problem so far. We then
find the ratio $\sigma_n/\sigma_{\text{total}}$ by calculating the number of
scalar jets one would observe at high center-of-mass energies. We will present
our results for $\phi^3$ theory in four and six spacetime dimensions, $\phi^4$
and the broken theories in four spacetime dimensions.
