The Problebility Of Discovrying η_b Through η_b→J/ψ+γ

In 1977,Professor (LENGEND) discovered the mesonΥ(bˉb). On theory,the peo-ple thought that,the meson must think that it may not be exist in the world.We dis-cussed the decayη_b→J/ψ+γ,researched the decay can afford a method to detectthe meson or not.The basic thought of this paper is that,On the base of the B-S equation,we hopewe can calculate the outcome though QCD,getting the decay width and the Branchingratio. The material is that,based on the fermi formula and the process of the decay ,wemake a attempt;We predigest the equation of theη_band the J/ψfor calculation. Andthen,we make a factorial process,got the result.Finaly,we get the Branching ratio ofη_b→J/ψ+γ.At last,we compare the result with the other academicians. though the branchratio is about 10^-7,we think that,as the technic got ahead ,Maybe,the decayη_b→J/ψ+γis a good way to research theη_b .we hope that we can provide some usefuland much more all-around methods to understandη_b .
