Regge trajectories of ordinary and non-ordinary mesons from their scattering poles

J. Nebreda, J. A. Carrasco, J. T. Londergan +2

Our results on obtaining the Regge trajectory of a resonance from its pole in a scattering process and from analytic constraints in the complex angular momentum plane are presented…

Remarks on pole trajectories for resonances

C. Hanhart, J. R. Pelaez, G. Rios

We discuss in general terms pole trajectories of resonances coupling to a continuum channel as some strength parameter is varied. It is demonstrated that, regardless the underlying…

The non-ordinary Regge behavior of the meson

J. R. Peláez, J. T. Londergan, J. Nebreda +1

We review how the Regge trajectory of an elastic resonance can be obtained just from its pole position and coupling, by means of a dispersive formalism. This allows to deal correct…

Non-ordinary nature of the f_0(500) resonance from its Regge trajectory

J. Nebreda, J. T. Londergan, J. R. Pelaez +1

We report our results on how to obtain the Regge trajectory of a resonance from its pole in a scattering process by imposing analytic constraints in the complex angular momentum pl…

Regge trajectory of the f_0(500) resonance from a dispersive connection to its pole

J. Nebreda, J. T. Londergan, J. R. Pelaez +1

We report here our results on how to obtain the Regge trajectory of a resonance from its pole in a scattering process by imposing analytic constraints in the complex angular moment…
