note = {We study constraints on the Universal Extra Dimension (UED) by taking into account current results of the Large Hadron Collider (LHC). We focus on three types of phenomennological issues, namely Higgs production and decay processes at the LHC, the electroweak precision measurement, and the vacuum stability. We studied seven types of six-dimensional UED models as well as five-dimensional one. We have found that the Higgs signal strength gives typical lower bounds on compactification scale of extra dimension(s) as 650 GeV for the five-dimensional model and 800–1400 GeV for the six-dimensional models, respectively. The electroweak S; T parameters also give 700 GeV for the five-dimensional model and 900–1500 GeV for the six-dimensional models, respectively. We have estimated the ultraviolet cutoff scale in higher dimensional theory by vacuum stability bound by using four-dimensional effective theory approach., 学位の種類: 博士（理学）. 報告番号: 甲第3909号. 学位記番号: 新大院博（理）甲第378号. 学位授与年月日: 平成26年3月24日, 新大院博（理）甲第378号},
