$\ddot{I}(770{)}^0$, K${}^{\ast }(892{)}^0$ and f${}_0(980)$ Production in Au-Au and pp Collisions at $\sqrt{s_{NN}}$ = 200 GeV

Abstract

Preliminary results on $\ddot{I}(770{)}^0\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}$, K${}^{\ast }(892{)}^0\to \ddot{I}€$K and $f_0(980)\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}$ production using the mixed-event technique are presented. The measurements are performed at mid-rapidity by the STAR detector in $\sqrt{s_{NN}}$= 200 GeV Au-Au and pp interactions at RHIC. The results are compared to different measurements at various energies.
