suppression pattern of neutral pions at high transverse momentum in au plus au collisions at root s nn 200 gev and constraints on Medium Transport coefficients
Physical Review Letters, 2008Co-Authors: A. Adare, S. Afanasiev, N. N. Ajitanand, Y. Akiba, James Alexander, K. Aoki, C Aidala, H Albataineh, A Aljamel, L AphecetcheAbstract:For Au + Au collisions at 200 GeV, we measure neutral pion production with good statistics for transverse momentum, p(T), up to 20 GeV/c. A fivefold suppression is found, which is essentially constant for 5 in the parton quenching model. The spectral shape is similar for all collision classes, and the suppression does not saturate in Au + Au collisions.

Quantitative constraints on the Transport properties of hot partonic matter from semi-inclusive single high transverse momentum pion suppression in Au+Au collisions at sNN=200 GeV
Physical Review C, 2008Co-Authors: A. Adare, S. Afanasiev, Christine Angela Aidala, N. N. Ajitanand, Y. Akiba, H. Al-bataineh, James Alexander, Ahmed Al-jamel, K. Aoki, Laurent Bernard AphecetcheAbstract:The PHENIX experiment has measured the suppression of semi-inclusive single high-transverse-momentum pi(0)'s in Au+Au collisions at root s(NN) = 200 GeV. The present understanding of this suppression is in terms of energy loss of the parent (fragmenting) parton in a dense color-charge Medium. We have performed a quantitative comparison between various parton energy-loss models and our experimental data. The statistical point-to-point uncorrelated as well as correlated systematic uncertainties are taken into account in the comparison. We detail this methodology and the resulting constraint on the model parameters, such as the initial color-charge density dN(g)/dy, the Medium Transport coefficient , or the initial energy-loss parameter epsilon(0). We find that high-transverse-momentum pi(0) suppression in Au+Au collisions has sufficient precision to constrain these model-dependent parameters at the +/- 20-25% (one standard deviation) level. These constraints include only the experimental uncertainties, and further studies are needed to compute the corresponding theoretical uncertainties.

Aoki, C Aidala, Laurent Bernard AphecetcheAbstract:The PHENIX experiment has measured the suppression of semi-inclusive single high transverse momentum pi^0's in Au+Au collisions at sqrt(s_NN) = 200 GeV.
