The inclusion of new ingredients that are expected to be specially relevant at higher energies could reveal more information about the physics behind the NLO terms of the chiral Lagrangian. In the present work, we explore the relevance of including partial waves higher than the L = 0, which is usually the only component considered in the literature to study the K̅N scattering phenomenology. In particular, we focus on the p-wave contribution, the effect of which is expected to be non-negligible, as we aim at obtaining the K−p scattering amplitudes at higher energies, necessary to describe the ηΛ, ηΣ0, K0Ξ0 and K+Ξ− production reactions. Extending the K̅N interaction to p-wave components is also relevant for studies of bound K− mesons in nuclei since their local momentum can acquire sizable values.
