Abstract

We report the measurement of the transverse momentum dependence of inclusive J/ψ polarization in p+p collisions at √s=200GeV performed by the PHENIX Experiment at the Relativistic Heavy Ion Collider. The J/ψ polarization is studied in the helicity, Gottfried-Jackson, and Collins-Soper frames for pT<5GeV/c and |y|<0.35. The polarization in the helicity and Gottfried-Jackson frames is consistent with zero for all transverse momenta, with a slight (1.8 sigma) trend towards longitudinal polarization for transverse momenta above 2GeV/c. No conclusion is allowed due to the limited acceptance in the Collins-Soper frame and the uncertainties of the current data. The results are compared to observations for other collision systems and center of mass energies and to different quarkonia production models.

The J/ψ polarization is studied in the helicity, Gottfried-Jackson, and Collins-Soper frames for pT<5GeV/c and |y|<0.35. The polarization in the helicity and Gottfried-Jackson frames is consistent with zero for all transverse momenta, with a slight (1.8 sigma) trend towards longitudinal polarization for transverse momenta above 2GeV/c. No conclusion is allowed due to the limited acceptance in the Collins-Soper frame and the uncertainties of the current data. The results are compared to observations for other collision systems and center of mass energies and to different quarkonia production models.",

N2 - We report the measurement of the transverse momentum dependence of inclusive J/ψ polarization in p+p collisions at √s=200GeV performed by the PHENIX Experiment at the Relativistic Heavy Ion Collider. The J/ψ polarization is studied in the helicity, Gottfried-Jackson, and Collins-Soper frames for pT<5GeV/c and |y|<0.35. The polarization in the helicity and Gottfried-Jackson frames is consistent with zero for all transverse momenta, with a slight (1.8 sigma) trend towards longitudinal polarization for transverse momenta above 2GeV/c. No conclusion is allowed due to the limited acceptance in the Collins-Soper frame and the uncertainties of the current data. The results are compared to observations for other collision systems and center of mass energies and to different quarkonia production models.

AB - We report the measurement of the transverse momentum dependence of inclusive J/ψ polarization in p+p collisions at √s=200GeV performed by the PHENIX Experiment at the Relativistic Heavy Ion Collider. The J/ψ polarization is studied in the helicity, Gottfried-Jackson, and Collins-Soper frames for pT<5GeV/c and |y|<0.35. The polarization in the helicity and Gottfried-Jackson frames is consistent with zero for all transverse momenta, with a slight (1.8 sigma) trend towards longitudinal polarization for transverse momenta above 2GeV/c. No conclusion is allowed due to the limited acceptance in the Collins-Soper frame and the uncertainties of the current data. The results are compared to observations for other collision systems and center of mass energies and to different quarkonia production models.
