STAR Results from Au + Au Fixed-Target Collisions at sqrt(s_NN) = 4.5 GeV

Understand

We present results from STAR's first dedicated fixed-target run conducted in 2015 with Au + Au collisions at sqrt(s_NN) = 4.5 GeV.

• Directed flow of protons and lambdas, elliptic flow of identified hadrons, HBT radii, as well as pion, K^0_s, 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.
