We study kaon-nucleon interactions in the Skyrme model by using a modified bound state approach, where the kaon is introduced around the physical nucleon. The method is more suited to the study of weakly interacting kaon-nucleon systems. We have found a bound state with binding energy of order ten MeV. We also discuss theKN interaction and find that it consists of an attraction in the middle range and a repulsion in the short range.

“…In addition to the non-resonant S -wave, the resonant π-π S -wave with a pole at (512± 15)− i(188±12) MeV, interpreted as the broad σ meson, plays an essential role in the η → πππ decays. Due to the large interference between non-resonant and resonant S -waves, only the sum is used to describe the S -wave contribution, and the branching fractions Theoretically the non-resonant part of coupling in η → γπ + π − is accounted for by the higher term of Wess-Zumino-Witten (WZW) ChPT Lagrangian [26](also known as the box anomaly). However the decay dynamics of η → γπ + π − has been explored with very limited statistics only and new measurements are needed to clarify the scenario.…”

“…[6] it was argued that this picture is not complete, but that a Wess-Zumino-Witten (WZW) term [7] should be added to the Lagrangian of the model. WZW terms typically occur if the symmetry breaking at the scale Λ is facilitated by some strong dynamics.…”

In the popular littlest Higgs model, T-parity can be broken by Wess-Zumino-Witten (WZW) terms induced by a strongly coupled UV completion. On the other hand, certain models with multiple scalar multiplets (called moose models) permit the implementation of T-parity such that it is not broken by the WZW terms. Here we present a concrete realization of such a model, and discuss the phenomenology at the Large Hadron Collider, in particular differences with respect to the littlest Higgs model. AbstractIn the popular littlest Higgs model, T-parity can be broken by Wess-Zumino-Witten (WZW) terms induced by a strongly coupled UV completion. On the other hand, certain models with multiple scalar multiplets (called moose models) permit the implementation of an exchange symmetry (X-parity) such that it is not broken by the WZW terms. Here we present a concrete and realistic construction of such a model. The little Higgs model with X-Parity is a concrete and realistic implementation of this idea. In this contribution, the properties of the model are reviewed and the collider phenomenology is discussed in some detail. We also present new results on the decay properties and LHC signatures of the light triplet scalars that are predicted by this model.
