Techni-dilaton at 125 GeV

Year: 2012

Type: article

Abstract: Walking technicolor predicts a light composite scalar, techni-dilaton, arising as a pseudo-Nambu-Goldstone boson for the approximate scale symmetry spontaneously broken by techni-fermion condensation. We show that a light techni-dilaton with a mass of around 125 GeV can explain presently observed excesses particularly in the di-photon decay channel at the LHC.
