Technipion limits from LHC Higgs searches (pg 84, 115025, 2011)

In [1] the authors used the results of LHC searches for the standard model Higgs boson in the tau tau decay mode to place strong constraints on the light technipion state predicted in technicolor models that include colored technifermions. The results from the analyses [2-4] quoted there (and used in Fig, 3 of [1]), however, arose in large part from the production of a standard model Higgs boson through vector-boson fusion or in association with a W boson-production mechanisms that are absent for technipions [1]. In this paper, updated results on searches for the Higgs in the tau tau decay mode from the ATLAS experiment [5] are used instead. Using Higgs results from the gluon fusion production mode only, which is common to both the standard model Higgs and technipions, we show that constraints on light technipions in models with colored technifermions are very similar to that quoted in the original paper [1].
