1. Towards a precise determination of the scattering amplitudes of the charmed and light-flavor pseudoscalar mesons / Guo, Zhi-Hui ; Liu, Liuming ; Meißner, Ulf-G. ; Oller, J. A. ; et al
We study the scattering of the light-flavor pseudoscalar mesons ( π,K,η ) off the ground-state charmed mesons ( D,Ds ) within chiral effective field theory. [...]

3. Derivation of spontaneously broken gauge symmetry from the consistency of effective field theory II: Scalar field self-interactions and the electromagnetic interaction / Djukanovic, D. ; Gegelia, J. ; Meißner, Ulf-G.
We extend our study of deriving the local gauge invariance with spontaneous symmetry breaking in the context of an effective field theory by considering self-interactions of the scalar field and inclusion of the electromagnetic interaction. [...]

4. Towards a new paradigm for heavy-light meson spectroscopy / Du, Meng-Lin ; Albaladejo, Miguel ; Fernandez-Soler, Pedro ; Guo, Feng-Kun ; et al
Since 2003 many new hadrons, including the lowest-lying positive-parity charm-strange mesons Ds0*(2317) and Ds1(2460), have been observed that do not conform with quark-model expectations. [...]
