Probing the structure of χc1 (3872) with photon transition form factors
(2023) In Physical Review D 107(7).- Abstract
We propose studying the structure of the χc1(3872) axial vector meson through its γL∗γ→χc1(3872) transition form factor. We derive a light-front wave function representation of the form factor for the lowest cc¯ Fock state. We found that the reduced width of the state is well within the current experimental bound recently published by the Belle Collaboration. This strongly suggests a crucial role of the cc¯ Fock-state in the photon-induced production. Our results for the Q2 dependence can be tested by future single-tagged e+e- experiments, giving further insight into the short-distance structure of this meson.
