What can we learn from a second phi meson peak in ultrarelativistic nuclear collisions?
The decay width of a phi meson is reduced from its vacuum value as its mass decreases in hot hadronic matter as a result of the partial restoration of chiral symmetry. This reduction is, however, cancelled by collisional broadening through the reactions $\phi\pi\to KK^*$, $\phi K\to\phi K$, $\phi\rh...
