Abstract
The existence of a glueball has been a tough work for many years study. Utilizing the well developed QCD theory for meson decays, we propose a new way to identify whether a scalar glueball existed or not. In the presence of mixing between glueballs and ordinary scalar mesons, we explore the possibility to extract the mixing parameters from semileptonic B decays and nonleptonic B decays. We also point out a clean way to identify a glueball through decays.
