Shinya Matsuzaki

TL;DR
This paper discusses the light technidilaton as a Higgs candidate within walking technicolor models, emphasizing LHC phenomenology, the role of the anti-Veneziano limit, and potential signals of new composite particles at LHC-Run II.
Contribution
It provides a phenomenological analysis of the technidilaton and other technihadrons in light of LHC data, highlighting the anti-Veneziano limit's role in their lightness and detectability.
Findings
Technidilaton can be consistent with LHC data as a light composite Higgs.
Predicted technipions and technirho mesons could be observable at LHC-Run II.
The anti-Veneziano limit supports the lightness of the technidilaton.
Abstract
The LHC Higgs can be identified as the technidilaton, a composite scalar, arising as a pseudo Nambu-Goldstone boson for the spontaneous breaking of scale symmetry in walking technicolor. One interesting candidate for the walking technicolor is the QCD with the large number of fermion flavors, involving the one-family model having the eight-fermion flavors. The smallness of the technidilaton mass can be ensured by the generic walking feature, Miransky scaling, and the presence of the "anti-Veneziano limit" characteristic to the large-flavor walking scenario. To tell the standard-model Higgs from the technidilaton, one needs to wait for the precise estimate of the Higgs couplings to the standard model particles, which is expected at the ongoing LHC-Run II. In this talk the technidilaton phenomenology in comparison with the LHC Run-I data is summarized with the special emphasis placed on…
