Description
More than twenty years have elapsed since the discovery of $\chi_{c1}(3872)$ previously denoted as $X(3872)$, and an impressive amount of theoretical and experimental studies has been devoted to its properties, decays and production mechanisms.
Despite the extensive work, a full understanding of the nature of $\chi_{c1}(3872)$ is still missing.
In the present study I reconsider a theoretical framework based on the heavy quark large mass limit to analyze the radiative decays of heavy quarkonia, in particular the electric dipole transitions of $\chi_{c1}(2P)$ to $S$-wave charmonia.
The results favorably compare to recent measurements for $\chi_{c1}(3872)$, obtained by the LHCb Collaboration, if this meson is identified with $\chi_{c1}(2P)$.
