We study the effect of in-medium mass-shift on transverse-momentum spectrum and elliptic anisotropy of $\phi$ meson. It is found that the mass-shift enhances the $\phi$ yields and suppresses the elliptic flow $v_2$ in large momentum region, and the effects increase with the increasing mass-shift. The effects are various for different sources and decrease with the increasing expanding velocity. We further study the effects for parts of all $\phi$ meson with mass-shift, and the effects decrease with the decreasing probability of $\phi$ meson with mass-shift. Since the different mass-shift lead to different transverse-momentum spectrum and $v_2$, our study may provide a way to restrict the ranges of in-medium mass-shift of $\phi$ meson in high-energy heavy-ion collisions. |
