title = "Hyperon resonances with spin-5/2 in kaon photoproduction",
abstract = "The effects of spin-5/2 hyperon resonances have been investigated in the photoproduction of kaon γp → K+Λ. To this end, we used the previously constructed isobar model and included a number of hyperon resonances in the u-channel of the background terms to investigated the effect of spin-5/2 hyperon resonances. To construct the vertex we followed the prescription of Pascalutsa, whereas to model the high-spin propagator we have adopted the recipe of Vrancx. We regularized the u-channel in order to avoid the singularity, since numerically the value of Mandelstam variable u could be zero. By minimizing the value of χ2 we have improved the consistency of the model to the experimental data, especially in the case of the cross-section and polarization observables. We have found that the spin-5/2 hyperon resonances contribute significantly to the kaon photoproduction process, especially in the backward directions.",
