Higgs Production and Decay in the Little Higgs Model

We analyse the consequences of the little Higgs model for double Higgs boson production at the LHC and for the partial decay width ( H ! ). In particular, we study the sensitivity of these processes in terms of the parameters of the model. We nd that a generic prediction is that the partial width ( H ! ) is greatly suppressed with respect to the standard model due to a cancellation between the contributions from the charged vector particles. This is a robust prediction of the little Higgs model.On the other hand, the little Higgs model does not change signicantly either single or double Higgs production at hadron colliders.
