Hadronic-loop induced mass shifts in scalar heavy-light mesons
Hadronic-loop induced mass shifts in scalar heavy-light mesons
We calculate the mass shifts of heavy-light scalar mesons due to hadronic loops under the assumption that these vanish for the groundstate heavy-light mesons. The results show that the masses calculated in quark models can be reduced significantly. We stress that the mass alone is not a signal for a...

We calculate the mass shifts of heavy-light scalar mesons due to hadronic loops under the assumption that these vanish for the groundstate heavy-light mesons. The results show that the masses calculated in quark models can be reduced significantly. We stress that the mass alone is not a signal for a molecular interpretation. Both the resulting mass and the width suggest the observed D-0* state could be a dressed c (q) over bar state. We give further predictions for the bottom scalar mesons which can be used to test the dressing mechanism. (C) 2008 Elsevier B.V. All rights reserved. |
