Query: Spectral functions of strange vector mesons in asymmetric hyperonic
  matter   We study the medium modifications of the spectral functions as well as
production cross-sections of the strange vector mesons ($\phi$, $K^*$ and $\bar
{K^*}$) in isospin asymmetric strange hadronic matter. These are obtained from
the in-medium masses of the open strange mesons and the decay widths $\phi
\rightarrow K\bar K$, $K^* \rightarrow K\pi$ and $\bar {K^*} \rightarrow {\bar
K}\pi$ in the hadronic medium. The decay widths are computed using a field
theoretic model of composite hadrons with quark/antiquark constituents, from
the matrix element of the light quark-antiquark pair creation term of the free
Dirac Hamiltonian between the initial and final states. The matrix element is
multiplied with a coupling strength parameter for the light quark-antiquark
pair creation, which is fitted to the observed vacuum decay width of the decay
process. There are observed to be substantial modifications of the spectral
functions as well as production cross-sections of these vector mesons due to
isospin asymmetry as well as strangeness of the hadronic medum at high
densities. These studies should have observable consequences, e.g. in the yield
of the hidden and open strange mesons arising from the isospin asymmetric high
energy heavy ion collisions at the Compressed baryonic matter (CBM) experiments
at the future facility at GSI.
