Study of Baryon Number Transport Dynamics and Strangeness Conservation Effects Using -hadron Correlations
In nuclear collisions at RHIC energies, an excess of hyperons over
is observed, indicating that carries a net baryon
number despite and quarks being produced in pairs. The baryon
number in could have been transported from the incident nuclei and/or
acquired and balanced in baryon pair productions associated with other types of
anti-hyperons, such as . To investigate these two scenarios, we
propose to measure correlations between and , as well as between
and anti-hyperons. We will use two versions, the default and
string-melting, of a multiphase transport (AMPT) model to illustrate the
correlation method. We will present the -hadron correlations from
simulated Au+Au collisions at and 14.6 GeV, and discuss
the dependence on collision energy and on the hadronization scheme in these two
AMPT versions. These correlations from the AMPT model provide a baseline for
experimental exploration of the dynamics of baryon number transport and the
effects of baryon number and strangeness conservation in nuclear collisions
