Event Structure and Double Helicity Asymmetry in Jet Production from Polarized p+p Collisions at sqrt(s) = 200 GeV

We report on event structure and double helicity asymmetry (\(A_LL\)) of jet production in longitudinally polarized p+p collisions at \(\sqrt{s}\)=200 GeV. Photons and charged particles were measured at midrapidity \(|\eta| < 0.35\) with the requirement of a high-momentum (\(>2\) GeV/\(c\)) ph...
