Hadronic loop effects to excited scalar charmed mesons revisited

Mohammad H. Alhakami, Numa A. Althubiti, Nwuyer A. Al-shammari

We re-examine the hadronic loop effects to the masses of $D_0^{\ast }$ and $D_{s0}^{\ast }$ calculated in quark models in the framework of heavy meson chiral perturbation theory (HMCHPT). The…
