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…
New limits on intrinsic charm in the nucleon from global analysis of parton distributions
P. Jimenez-Delgado, T. J. Hobbs, J. T. Londergan +1
We present a new global QCD analysis of parton distribution functions, allowing for possible intrinsic charm (IC) contributions in the nucleon inspired by light-front models. The a…
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…
Identification of non-ordinary mesons from the dispersive connection between their poles and their Regge trajectories: the f0(500) resonance
J. T. Londergan, J. Nebreda, J. R. Pelaez +1
We show how the Regge trajectory of a resonance can be obtained from its pole in a scattering process and analytic constraints in the complex angular momentum plane. The method is…
Phenomenology of nonperturbative charm in the nucleon
T. J. Hobbs, J. T. Londergan, W. Melnitchouk
We perform a comprehensive analysis of the role of nonperturbative (or intrinsic) charm in the nucleon, generated through Fock state expansions of the nucleon wave function involvi…
