Título: | Low-energy interactions of Nambu-Goldstone bosons with D mesons in covariant chiral perturbation theory |
Autor: | Geng, Li Sheng; Kaiser, N.; Weise, W.; Martín Cámalich, Jorge CSIC ORCID | Fecha de publicación: | 20-sep-2010 | Editor: | American Physical Society | Citación: | Physical Review - Section D - Particles and Fields 82 (5): 054022 (2010) | Resumen: | We calculate the scattering lengths of Nambu-Goldstone bosons interacting with D mesons in a covariant formulation of chiral perturbation theory, which satisfies heavy-quark spin symmetry and analytical properties of loop amplitudes. We compare our results with previous studies performed using heavy-meson chiral perturbation theory and show that recoil corrections are sizable in most cases. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevD.82.054022 | URI: | http://hdl.handle.net/10261/28418 | DOI: | 10.1103/PhysRevD.82.054022 | ISSN: | 1550-7998 |
