  In nuclear collisions at RHIC energies, an excess of $\Omega$ hyperons over
$\bar{\Omega}$ is observed, indicating that $\Omega$ carries a net baryon
number despite $s$ and $\bar{s}$ quarks being produced in pairs. The baryon
number in $\Omega$ could have been transported from the incident nuclei and/or
produced in baryon-pair production of $\Omega$ with other types of
anti-hyperons, such as $\bar{\Xi}$. To investigate these two scenarios, we
propose to measure correlations between $\Omega$ and $K$, as well as between
$\Omega$ and anti-hyperons. We will use two versions, the default and
string-melting, of a multiphase transport (AMPT) model to illustrate the method
to measure the correlation and to demonstrate the general shape of the
correlation. We will present the $\Omega$-hadron correlations from simulated
$\mathrm{Au}$+$\mathrm{Au}$ collisions at $\sqrt{s_{NN}} = 7.7$ and $14.6 \
\mathrm{GeV}$, and discuss the dependence on collision energy and on the
hadronization scheme in these two AMPT versions. These correlations can be used
to explore the mechanism of baryon number transport and the effects of baryon
number and strangeness conservation in nuclear collisions.
