Littlest Higgs model and 𝑊 pair production at international linear collider
Among the viable alternatives to the standard Higgs mechanism is the recently proposed Little Higgs model. The advantage here is that the model has an elementary light neutral scalar particle, which arises dynamically as against its ad hoc introduction in the standard model. The model also avoids hierarchy problem. We have investigated the 𝑊 pair production at ILC to study the littlest Higgs model using different observables. Specifically, polarization fraction of 𝑊 boson is expected to be measured very accurately at ILC. We use this to put limit on the scale parameter, 𝑓, in the model.
