> Title: "Longitudinal scaling property of the charged particle  
> balance function in Au + Au collisions $\sqrt{s_{NN}}$ = 200 GeV"
>
> Abstract: "We present measurements of the charged particle balance  
> function for diverse pseudorapidity and transverse momentum ranges  
> in Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV using the STAR  
> detector at RHIC. We observe that the balance function is boost- 
> invariant within the pseudorapidity coverage [-1.3,1.3]. The balance  
> function properly scaled by the width of the observed pseudorapidity  
> window does not depend on the position or size of the pseudorapidity  
> window. This scaling property also holds for particles in different  
> transverse momentum ranges. In addition, we find that the width of  
> the balance function decreases monotonically with increasing  
> transverse momentum for all centrality classes."
