The reaction e+e- --> hh recomputed

arXiv:0812.3750 · doi:10.1016/j.physletb.2009.04.022

Abstract

We notice that the existing literature about the reaction e+e- --> hh suffers from a mistake in the relative sign between the t-channel and u-channel graphs. Correcting this lowers the crosssections by about an order of magnitude.
