Abstract

The effects of the extended gauge sector present in the Littlest Higgs model in the reactions e{sup +}e{sup -} {yields} f{bar f} and e{sup +}e{sup -} {yields} Zh are examined. We find that the search reach at the 500 GeV ILC essentially covers the entire region where this model is relevant to the hierarchy proble and extends the reach of the LHC. In addition, we show that the ILC allows for an accurate determination of the model parameters, to the precision of a few percent, provided that the LHC measures the mass of the new heavy neutral gauge field.

Determination of Littlest Higgs Model Parameters at the ILC

Conley, John A. ; Hewett, JoAnne ; Le, My Phuong ; ... - Physical Review, D (Particles Fields)

We examine the effects of the extended gauge sector of the Littlest Higgs model in high energy e{sup +}e{sup -} collisions. We find that the search reach in e{sup +}e{sup -} {yields} f{bar f} at a {radical}s = 500 GeV International Linear Collider covers essentially the entire parameter region where the Littlest Higgs model is relevant to the gauge hierarchy problem. In addition, we show that this channel provides an accurate determination of the fundamental model parameters, to the precision of a few percent, provided that the LHC measures the mass of the heavy neutral gauge .eld.

Weak Mixing and Rare Decays in the Littlest Higgs Model

Bardeen, William A. ; /Fermilab

Little Higgs models have been introduced to resolve the fine-tuning problems associated with the stability of the electroweak scale and the constraints imposed by the precision electroweak analysis of experiments testing the Standard Model of particle physics. Flavor physics provides a sensitive probe of the new physics contained in these models at next-to-leading order.

THE LITTLEST HIGGS MODEL AND ONE-LOOP ELECTROWEAK PRECISION CONSTRAINTS.

CHEN, M.C. ; DAWSON,S.

We present in this talk the one-loop electroweak precision constraints in the Littlest Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. We find the one-loop contributions are comparable to the tree level corrections in some regions of parameter space. A low cutoff scale is allowed for a non-zero triplet VEV. Constraints on various other parameters in the model are also discussed. The role of triplet scalars in constructing a consistent renormalization scheme is emphasized.

Higgs boson decays in the littlest Higgs model

Gonzalez-Sprinberg, G.A. ; Martinez, R. ; Rodriguez, J.-Alexis - Physical Review. D, Particles Fields

We calculate the two body Higgs boson decays in the framework of the littlest Higgs model. The decay H{yields}{gamma}Z is computed at one-loop-level and, using previous results, we evaluate the branching fractions in the framework of the littlest Higgs model. A wide range of the space parameter of the model is considered and possible deviations from the standard model are explored.
