Polarization and cross section of midrapidity J/ψ production in p+p collisions at sqrt(s)=510 GeV

Autor: Acharya, U., Makek, Mihael, Zou, L.

The PHENIX experiment has measured the spin alignment for inclusive J/ψ→e+e− decays in p+p collisions at s√=510 GeV at midrapidity. The angular distributions have been measured in three different polarization frames, and the three decay angula

We report new measurements of inclusive pi production from frozen-spin HD for polarized photon beams covering the Delta(1232) resonance. These provide data simultaneously on both H and D with nearly complete angular distributions of the spin-differen
