Determination of chi_c and chi_b polarizations from dilepton angular distributions in radiative decays
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
The angular distributions of the decay products in the successive decays chi_c (chi_b) to J/psi (Upsilon) gamma and J/psi (Upsilon) to l+l- are calculated as a function of the angu…

Model-independent constraints on the shape parameters of dilepton angular distributions
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
The coefficients determining the dilepton decay angular distribution of vector particles obey certain positivity constraints and a rotation-invariant identity. These relations are…
