Towards the experimental clarification of quarkonium polarization
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
We highlight issues which are often underestimated in the experimental analyses on quarkonium polarization: the relation between the parameters of the angular distributions and the…
A new approach to quarkonium polarization studies
Pietro Faccioli, Carlos Lourenco, Joao Seixas
Significant progress in understanding quarkonium production requires improved polarization measurements, fully considering the intrinsic multidimensionality of the problem. We prop…
Rotation-invariant relations in vector meson decays into fermion pairs
Pietro Faccioli, Carlos Lourenco, Joao Seixas
The rotational properties of angular momentum eigenstates imply the existence of a frame-independent relation among the parameters of the decay distribution of vector mesons into f…
