Description

We report on several reactions involving baryons that develop triangle singularities. The combination of elements of chiral unitary theory with the triangle mechanisms explain different features of reactions and shed light on some decay modes of several resonances. We address the role of a triangle singularity in the πN(1535) contribution to γp→pπ0η, another singularity, producing a peak in the γp→K+Λ(1405) reaction which was previously unexplained, the role of a singularity in the πΔ decay of the N(1700), and also discuss the N∗ (1875) resonance from this perspective.
