Invisible Higgs in large extra dimensions
Jari Laamanen
Abstract
We discuss the possibility of detecting a Higgs boson in electron-positron collider experiments if large extra dimensions are realized in nature. In such a case, the Higgs boson can decay invisibly by oscillating into a graviscalar Kaluza-Klein (KK) tower. We show that the search for such a Higgs at an e+ e- linear collider entails more complications than are usually thought of in relation to an invisibly decaying Higgs.
