Scalar resonances in the decay
L. Roca, E. Oset
We study theoretically the resonant structure of the double Cabibbo suppressed decay. We start from an elementary production diagram, considered subleading in p…
Discerning the two poles in decay
G. Y. Wang, L. Roca, E. Oset
Within the chiral unitary approach, the axial-vector resonance has been predicted to manifest a two-pole nature. The lowest pole has a mass of 1195 Mev and a width of 2…
decay into a pseudoscalar and an axial-vector meson
L. R. Dai, L. Roca, E. Oset
We study theoretically the decay , with a or and an axial-vector resonance , , , , o…
On the isospin 0 and 1 resonances from photoproduction data
L. Roca, E. Oset
Recently we presented a successful strategy to extract the position of the two poles from experimental photoproduction data on the reaction at Jeffe…
Selected topics on Hadrons in Nuclei
E. Oset, M. Kaskulov, E. Hernandez +8
In this talk we report on selected topics on hadrons in nuclei. The first topic is the renormalization of the width of the in a nuclear medium. This is followed by a shor…
Nature of the axial-vector mesons from their Nc behavior within the chiral unitary approach
L. S. Geng, E. Oset, J. R. Pelaez +1
By describing within the chiral unitary approach the s-wave interaction of the vector meson nonet with the octet of pseudoscalar Goldstone Bosons, we find that the main component o…
Radiative decay into of the low lying axial-vector mesons
H. Nagahiro, L. Roca, E. Oset
We evaluate the radiative decay into a pseudoscalar meson and a photon of the whole set of the axial-vector mesons dynamically generated from the vector-pseudoscalar meson () i…
Clues for the existence of two resonances
L. S. Geng, E. Oset, L. Roca +1
The axial vector meson was studied within the chiral unitary approach, where it was shown that it has a two-pole structure. We reanalyze the high-statistics WA3 experim…
