The appearance of strangeness in the form of hyperons within the inner coreof neutron stars is expected to affect its detectable properties such as itsglobal structure or gravitational wave emission. In this work, we explore theparameter space of hyperonic stars within the framework of the RelativisticMean Field model allowed by present uncertainties in state-of-the-art nuclearand hypernuclear experimental data. We impose multi-physics constraints atdifferent density regimes to restrict the parameter space: Chiral effectivefield theory, heavy-ion collision data as well as multi-messenger astrophysicalobservations of neutron stars. We investigate possible correlations betweenempirical nuclear and hypernuclear parameters, particularly the symmetry energyand its slope, with observable properties of neutron stars. We do not find acorrelation for the hyperon parameters and the astrophysical data. However, theinclusion of hyperons generates a tension between the astrophysical and heavyion data constraining considerable the available parameter space.
