In-medium modification of $\rho$-mesons produced in heavy ion collisions

V. L. Eletsky, B. L. Ioffe, J. I. Kapusta

The mass shift $\Delta m_{\rho }$ and width broadening $\Delta {\Gamma }_{\rho }$ of $\rho$ mesons produced in heavy ion collisions is estimated using a general formula which relates the in-medium mass shift of a pa…
