Recent work has brought renewed attention to the possibility that the cross\nsection for producing n Higgs bosons grows large with n at a sufficiently\nenergetic hadron collider. In particular, this "Higgsplosion'" mechanism has\nbeen suggested as a solution to the hierarchy problem. We investigate the\nphenomenology of this scenario. Discovery is trivial, so we consider several\nvariables for use in measuring large Higgs multiplicities and evaluate their\neffectiveness. We find that a 10% level measurement of the number of Higgs\nbosons is possible with a handful of events, using the scalar sum of jet\ntransverse momenta, but determining the exact multiplicity may take a few\nthousand events, depending on the degree of statistical significance desired\nfor the measurement. While this situation may be acceptable given the\npotentially large cross sections in this scenario, future research to improve\nthe measurement is warranted.\n
