Abstract
We report results on event-by-event fluctuations in mean transverse momentum in AuAu collisions at\(\sqrt {^s NN} = 130\) GeV measured by the STAR experiment at RHIC. The dynamical fluctuations,\(\sigma _{\langle P_t \rangle ,dynam} \) is found to be about 1.2 ±02% of the mean transverse momentum for particles in pseudo-rapidity range of −0.5 < η < 0.5 and for the top 6% central collisions.
