We present results from STAR's first dedicated fixed-target run conducted in 2015 with Au + Au collisions at root SNN = 4.5 GeV. Directed flow of protons and lambdas, elliptic flow of identified hadrons, HBT radii, as well as pion, Ks, and Lambda spectra are compared with previous results from the AGS. These results demonstrate that STAR has good event reconstruction and particle identification capabilities in the fixed-target configuration. The implications of these results on future STAR fixed-target runs are discussed.

Abstract
We present results from STAR's first dedicated fixed-target run conducted in 2015 with Au + Au collisions at root SNN = 4.5 GeV. Directed flow of protons and lambdas, elliptic flow of identified hadrons, HBT radii, as well as pion, Ks, and Lambda spectra are compared with previous results from the AGS. These results demonstrate that STAR has good event reconstruction and particle identification capabilities in the fixed-target configuration. The implications of these results on future STAR fixed-target runs are discussed.File in questo prodotto:
