H. and Oset, E.", title="Triangle mechanisms in the build up and decay of the N*(1875)", journal="Physical Review C", year="2017", publisher="Amer Physical Soc", volume="96", number="3", pages="035202--14pp", abstract="We studied the N*(1875)(3/ 2-) resonance with a multichannel unitary scheme, considering the Delta pi and Sigma * K, with their interaction extracted from chiral Lagrangians, and then added two more channels, the N*(1535) p and N sigma, which proceed via triangle diagrams involving the Sigma * K and Delta pi respectively in the intermediate states. The triangle diagram in the N*(1535) p case develops a singularity at the same energy as the resonance mass. We determined the couplings of the resonance to the different channels and the partial decay widths. We found a very large decay width to Sigma * K, and also observed that, due to interference with other terms, the N sigma channel has an important role in the pi pi mass distributions at low invariant masses, leading to an apparently large N sigma decay width. We discuss justifying the convenience of an experimental reanalysis of this resonance, in light of the findings of the paper, using multichannel unitary schemes.", optnote="WOS:000409256500008", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3283), last updated on Tue, 19 Sep 2017 10:20:50 +0000", issn="2469-9985", doi="10.1103/PhysRevC.96.035202", opturl="http://arxiv.org/abs/1703.09872", opturl="https://doi.org/10.1103/PhysRevC.96.035202", archivePrefix="arXiv", eprint="1703.09872", language="English" }
