摘要: The Georgi-Machacek model predicts the existence of four neutral Higgs bosons, one which can be identied as 125-GeV boson. latest data favor parameter space small mixing anglebetween two custodial singlets model. other bosons belong respectively to triplet and quintet. We study general decay production properties these parti- cles in small-� scenario. Constraints on SU(2)L vacuum expectation value are obtained a function exotic boson masses using ATLAS various search channels for additional bosons.
