Abstract
We report on the first measurement of the double-spin asymmetry, A LL, of electrons from the decays of hadrons containing heavy flavor in longitudinally polarized p+p collisions at √s=200 GeV for p T=0.5 to 3.0 GeV/c. The asymmetry was measured at midrapidity (

η

<0.35) with the PHENIX detector at the Relativistic Heavy Ion Collider. The measured asymmetries are consistent with zero within the statistical errors. We obtained a constraint for the polarized gluon distribution in the proton of(1σ) based on a leading-order perturbative quantum chromodynamics model, using the measured asymmetry. © 2013 American Physical Society.
