| contents | This paper examines the impacts of the squeezing effect caused by the particle's in-medium mass modification on the three-dimensional Hanbury Brown-Twiss (HBT) radii. An analysis is conducted on how the squeezing effect impacts the three-dimensional HBT radii of $ϕϕ$, $D^0$$D^0$, and $K^+$$K^+$. The squeezing effect suppresses the impacts of transverse flow on the transverse source distribution and broadens the space-time rapidity distribution of the particle-emitting source, leading to an increase in the HBT radii, notably in out and longitudinal direction. This phenomenon becomes more significant for higher transverse pair momentum, resulting in a non-monotonic decrease in the HBT radii with increasing transverse pair momentum. The impact of the squeezing effect on the HBT radii is more pronounced for $D^0$$D^0$ than for $ϕϕ$. Furthermore, this effect is also more significant for $ϕ$$ϕ$ than for $K^+$$K^+$. The findings presented in this paper could offer fresh perspectives on investigating the squeezing effect. |
