The Lepton-Number-Violating Decays of and Mesons Induced by the Doubly Charged Higgs Boson
The lepton-number-violating decays of and mesons induced
by the doubly charged Higgs boson have been studied. It is found that although
the yielded results of the branch ratio are much smaller than the present
limits from the data they are consistent with the previous conclusions
calculated in the framwork of relativistic quark model where the processes
happened via the light Majorana neutrinos.Comment: version to appear in PR
Properties of X(3872) as a hadronic molecule with a negative parity
We discuss the possible interpretation of X(3872) as a hadronic
molecule with . Using the phenomenological Lagrangian
approach, we studied its radiative and strong decay properties. We find that
our model with about 97.6% isospin zero component explains the existing data
nicely. We predict the partial widths of the radiative and strong decays of
X(3872) and show that the measurement of the ratio may signal the nature
of X(3872).Comment: 5 pages, talk presented at The 4th International Workshop on Charm
