J/ polarization in 800-GeV p-Cu interactions Academic Article uri icon

abstract

  • The polarization of the J/ was measured with relatively high statistical precision only in fixed-target experiments, in pion and proton interactions with solid nuclear targets. No significant polarization was seen in either, with the exception of an intriguing large longitudinal polarization at the highest x F value of the pion-induced data. Thus, measurements in collider experiments, at energies and transverse momenta where theoretical calculations should be more robust and which were free of potential complications from nuclear effects, suffer from low statistics.
