Based on the collected data on J/ψ→ γKS0KS0η', the BESIII experiment has conducted an analysis of the mass and spin parity of the X(2370) particle. The findings are consistent with the characteristics expected of the lightest pseudoscalar glueball. We point out that further exploration of this particle's nature can be pursued through investigations of heavy bottom meson decays. Assuming the identity of X(2370) as a pseudoscalar glueball, we compute the form factors for B→ X(2370) transitions in the factorization approach. With these results, the estimated branching fractions for semileptonic B decays into X(2370) can reach the order of 10-6 and those for nonleptonic decays can reach the order 10-8. These results suggest that decays of B meson into X(2370) are detectable at experimental facilities like Belle-II. Future experimental endeavors hold promise in expanding our understanding of glueball physics, contributing to the ongoing exploration surrounding this intriguing particle.
