Anomalous Higgs interactions in dimensional deconstruction
Nobuaki Kurahashi, C. S. Lim, Kazuya Tanabe
Recent LHC experiments have revealed that Higgs is light. As an interesting candidate to accommodate light Higgs, in this paper we adopt the scenario of dimensional deconstruction,…

We address a question whether the recently observed Higgs mass GeV, of the order of the weak scale , is calculable as a finite value in the scnenario of gauge-…
