Measurements of Forward Jet Production in Polarized pp Collisions at \sqrt{s}=500 GeV

Understand

The AnDY project at RHIC was proposed to measure the analyzing power for Drell-Yan production.

• Test runs took place during polarized proton operations of RHIC in 2011 and 2012 with a model of the AnDY apparatus in place.
• In total, an integrated luminosity of 9 pb^-1 with beam polarization of 50% was sampled.
• The primary detector components were a hadron calorimeter (HCal) that spanned the pseudorapidity interval 2.4 < \eta < 4.0 and a small electromagnetic calorimeter (ECal).
