Systematic Study of Azimuthal Anisotropy in Cu $+$ Cu and Au $+$ Au Collisions at $s_{_{N N}} = 62.4$ and 200 GeV

A. Adare, S. Afanasiev, C. Aidala +421

We have studied the dependence of azimuthal anisotropy $v_{2}$ for inclusive and identified charged hadrons in Au $+$ Au and Cu $+$ Cu collisions on collision energy, species, and centra…

Inclusive cross sections, charge ratio and double-helicity asymmetries for $π^{+}$ and $π^{-}$ production in $p$ $+$ $p$ collisions at $s$ =200 GeV

A. Adare, C. Aidala, N. N. Ajitanand +378

We present the midrapidity charged pion invariant cross sections and the ratio of $π^{-}$ -to- $π^{+}$ production ( $5 < p_{T} < 13$ GeV/ $c$ ), together with the double-helicity asymmetries ($5<…

Design and performance of coded aperture optical elements for the CESR-TA x-ray beam size monitor

J. P. Alexander, A. Chatterjee, C. Conolly +11

We describe the design and performance of optical elements for an x-ray beam size monitor (xBSM), a device measuring $e^{+}$ and $e^{-}$ beam sizes in the CESR-TA storage ring. The dev…
