Final state interactions in nonleptonic hyperon decays
B. Borasoy, E. Marco
We investigate the importance of final state interactions in weak nonleptonic hyperon decays within a relativistic chiral unitary approach based on coupled channels. The effective…
Eta, eta-prime photoproduction and electroproduction off nucleons
B. Borasoy, E. Marco, S. Wetzel
The photo- and electroproduction of eta, eta-prime mesons on nucleons are investigated within a relativistic chiral unitary approach based on coupled channels. The s-wave potential…
Note on finite temperature sum rules for vector and axial-vector spectral functions
E. Marco, R. Hofmann, W. Weise
An updated analysis of vector and axial-vector spectral functions is presented. The resonant contributions to the spectral integrals are shown to be expressible as multiples of 4 p…
Final state interaction and a light mass "exotic" resonance
Steven D. Bass, Eugenio Marco
We investigate the possibility that the light-mass exotic mesons with J^PC=1^-+ observed at BNL and CERN may be resonances in the eta-pi and eta'-pi systems associated with the ano…
The phi --> pi^+ pi^- and phi radiative decays within a chiral unitary approach
E. Oset, S. Hirenzaki, E. Marco +3
We report on recent results on the decay of the phi into pi^+ pi^- and phi radiative decays into pi^0 pi^0 gamma and pi^0 eta gamma, which require the consideration of the final st…
QCD spectral sum rules and spontaneously broken chiral symmetry
E. Marco, W. Weise
The gap Delta = 4 pi f_pi ~ 1.2 GeV of spontaneous chiral symmetry breaking is introduced as a scale delineating resonance and continuum regions in the QCD spectral sum rules for v…
