The charge balance function (BF) is studied in Au − Au collisions at [Formula: see text] using the STAR detector. It is observed that within the acceptance (−1.3 < η < 1.3) of STAR Time Projection Chamber (TPC), the BF is independent of the position of the windows of same size, showing that BF is boost-invariant in the TPC accepted region. It is found that the BF measured in an observed window η w , B(δη|η w ), divided by [Formula: see text] is independent of the size and position of the observed window η w . These properties of BF hold for different transverse momenta and the width of BF decreases with the increasing of the latter. The result supports the delayed-hadronization scenario in thermal models.
