Description
In this talk, I will present our latest theoretical results regarding the exclusive double J/psi production at the B factory.
I will elucidate the reasons why the conventional NRQCD-based predictions for this process exhibit a notably poor convergence. I will then demonstrate that this convergence can be significantly enhanced by employing an improved NRQCD factorization approach. I will also present our most precise predictions, accurate up to NNLO QCD corrections, and discuss the detection prospects for this process.
