J. Adam, L. Adamczyk, J. R. Adams, J. K. Adkins et autres

The STAR collaboration reports a measurement of the transverse single-spin asymmetries, ${A}_{N}$, for neutral pions produced in polarized proton collisions with protons ($pp$), with aluminum nuclei ($p\mathrm{Al}$) and with gold nuclei ($p\mathrm{Au}$) at a nucleon-nucleon center-of-mass energy of 200 GeV. Neutral pions …

Charge-Dependent Directed Flow in Cu+Au Collisions at sNN=200 GeV

L. Adamczyk, J. K. Adkins, G. Agakishiev, M. M. Aggarwal et autres

We present the first measurement of charge-dependent directed flow in Cu+Au collisions at sqrt[s_{NN}]=200 GeV. The results are presented as a function of the particle transverse momentum and pseudorapidity for different centralities. A finite difference between the directed flow of positive and …
