Partonic structure of neutral pseudoscalars via two photon transition form factors

Khepani Raya, Minghui Ding, Adnan Bashir +2

The $\gamma {\gamma }^{\ast }\to {\eta }_{c,b}$ transition form factors are computed using a continuum approach to the two valence-body bound-state problem in relativistic quantum field theory, and ther…
