Quarkonium spectroscopy of the linear plus modified Yukawa potential
In this article, the linear plus modified Yukawa potential (LIMYP) is used as
the quark antiquark interaction potential for the approximate analytical bound
state solution of the Klein Gordon equation in three-dimensional space. The
energy eigenvalues and associated wavefunction are obtained by solving the
Klein Gordon equation analytically using the Nikiforov Uvarov (NU) method. The
mass spectra of heavy mesons such as charmonium , bottomonium
, and for various quantum states are obtained using the
energy spectra expression. In comparison to experimental data, graphical
modification of acquired mass spectra of heavy mesons with the parameter
employed in the energy equation and the current potential provides good
results.Comment: 17 pages, 24 figures, 3 table
Identification of newly observed singly charmed baryons using relativistic flux tube model
We calculate the mass spectra of , , ,
, and baryons in the framework of quark-diquark
configuration using relativistic flux tube model. The spin-dependent
interactions are included in the j-j coupling scheme to find complete mass
spectra. We satisfactorily describe the known singly charmed baryons in
quark-diquark configuration. The possible spin-parity quantum numbers
are assigned to several experimentally observed states. Furthermore, some
useful mass predictions are given for more excited states that are reasonably
consistent with other model predictions for lower excited states. {From the
obtained results the Regge trajectories for these singly charmed baryons are
constructed in the () plane and the properties like linearity,
parallelism and equidistant are verified.} Also, these predictions should be
tested in future experiments.Comment: 18 Pages, 9 figures Accepted in Phys. Rev.
