Consequences of the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>σ</mml:mi> </mml:math> -cut potential for the properties of neutron stars within the framework of the relativistic mean-field model based on chiral effective field

We explore the effect of the $\ensuremath{\sigma}$-cut potential on the properties of neutron stars with and without a hyperon core. The analysis involves two sets of nuclear interactions, QMC-RMF3 and QMC-RMF4, which are constructed from a relativistic mean-field model based on chiral effective field theory. The $\ensuremath{\sigma}$-cut potential plays a significant role in reducing the impact of the $\ensuremath{\sigma}$ field at high densities, leading to a stiffer equation of state while preserving nuclear matter properties at saturation density. The parameter ${f}_{s}$ regulates the influence of the $\ensuremath{\sigma}$-cut potential at high densities, with values determined by observational data. We also investigate the influence of the $\ensuremath{\sigma}$-cut potential on symmetric nuclear matter and symmetry energy. Our results align well with other theoretical and observational data.
