UNDERSTANDING THE PARTICLE PRODUCTION MECHANISM WITH CORRELATION STUDIES USING LONG AND SHORT RANGE CORRELATIONS

Long range forward-backward multiplicity correlations have been measured with the STAR detector for Au+Au collisions at $\sqrt{s_{NN}} = 200\, {\rm GeV}$. Strong long range correlations are observed in central Au+Au collisions. Based on the Dual Parton model and Color Glass Condensate considerations the data suggests that these long range correlations are due to multiple parton interactions. This suggests that dense partonic matter is created in central Au+Au collisions at $\sqrt{s_{NN}} = 200\, {\rm GeV}$.
