Abstract

The ATLAS and CMS groups have recently reported an excess at around 750 GeV with the local significance by about 3[Formula: see text] in the diphoton channel at the 13 TeV LHC. We give a possible explanation for the excess by a composite pseudo scalar [Formula: see text] predicted in the one-family model of walking technicolor.
