The $${\varvec{\Lambda (1405)}}$$ $\Lambda \left(1405\right)$ in resummed chiral effective field theory

Publikováno v: European Physical Journal

We study the unitarized meson–baryon scattering amplitude at leading order in the strangeness $$S=-1$$ S = - 1 sector using time-ordered perturbation theory for a manifestly Lorentz-invariant formulation of chiral effective field theory. By solving

Strategies for baryon resonance analysis

Autor: Döring, M., Hanhart, C., Huang, F., Krewald, S., Meissner, U.G.

Publikováno v: Chinese physics / C 33, 1127-1131 (2009).

The analytic properties of scattering amplitudes provide a meeting point for experimental and theoretical investigations of baryon resonances Pole positions and residues allow for a parameterization of resonances in a well-defined way which relates d

Charmed meson rescattering in the reaction pbar d to D Dbar N

Autor: Haidenbauer, J., Krein, G., Meissner, U.G., Sibirtsev, A.

Publikováno v: The European physical journal / A 37, 55-67 (2008). doi:10.1140/epja/i2008-10602-x

We examine the possibility to extract information about the DN and DbarN interactions from the pbar d to D Dbar N reaction. We utilize the notion that the open-charm mesons are first produced in the annihilation of the antiproton on one nucleon in th

Evidence that the Y(4660) is a f(0)(980)psi-prime bound state

Autor: Guo, F.-K., Hanhart, Chr., Meissner, U.G.

Publikováno v: Physics letters / B 665, 26-29 (2008). doi:10.1016/j.physletb.2008.05.057

We demonstrate that the experimental information currently available for the Y(4660) is consistent with its being an f(0)(980)psi' molecule. Possible experimental tests of our hypothesis are presented. (C) 2008 Elsevier B.V. All rights reserved.
