Latest results for the antikaon-nucleon optical potential
V. K. Magas, J. Yamagata-Sekihara, S. Hirenzaki +2
The key question of this letter is whether the K-nucleus optical potential is deep, as it is prefered by the phenomenological fits to kaonic atoms data, or shallow, as it comes out…
Three body systems with strangeness and exotic systems
E. Oset, A. Martinez Torres, K. P. Khemchandani +1
We report on four 's and three 's, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave resonances found by solving the Faddeev equations in the coupled…
Experimental status of deeply bound kaonic states in nuclei
V. K. Magas, J. Yamagata-Sekihara, S. Hirenzaki +2
We review recent claims of the existence of deeply bound kaonic states in nuclei. Also we study in details the (K-,p) reaction on C12 with 1 GeV/c momentum kaon beam, based on whic…
Perturbative Renormalizability of Chiral Two Pion Exchange and Power Counting in Nucleon-Nucleon Scattering
M. Pavon Valderrama
We show how to renormalize chiral two pion exchange perturbatively if one pion exchange has already been fully iterated at leading order. This particular choice corresponds to the…
Kaon induced Lambda(1405) production on a deuteron target at DAFNE
D. Jido, E. Oset, T. Sekihara
The K^- induced production of Lambda(1405) in the K^- d to pi Sigma n reaction is investigated having in mind the conditions of the DAFNE facility at Frascati where kaons are obtai…
Prediction of narrow and resonances with hidden charm above 4 GeV
Jia-Jun Wu, R. Molina, E. Oset +1
The interaction between various charmed mesons and charmed baryons are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. S…
