关于中子星中ρ介子凝聚的可能性
On the possibility of rho-meson condensation in neutron stars
摘要：
过去曾讨论过恒星和重离子碰撞中介子凝聚的可能性。在这里，我们研究了ρ介子凝聚（$ρ^{-}$）是否可以发生在非常密集的物质，并确定这种凝聚的强磁场的影响。我们发现，假设ρ质量由于介质效应而减小，ρ介子凝聚可以出现在中子星的核中。我们发现，磁场有一个不可忽视的作用，在触发凝聚。
英文摘要：
The possibility of meson condensation in stars and in heavy-ion collisions has been discussed in the past. Here, we study whether rho meson condensation ($ρ^{-}$) can occur in very dense matter and determine the effect of strong magnetic fields on this condensation. We find that rho meson condensates can appear in the core of the neutron star assuming a rho mass which is reduced due to in-medium effects. We find that the magnetic field has a non-negligible effect in triggering condensation.
