Production of $\hat{I}{\cdot }_b$ in ultra-peripheral $PbPb$ collisions

C. N. Azevedo, F. C. Sobrinho, F. S. Navarra

Very recently, the two-photon decay width of the $\hat{I}{\cdot }_b$ meson was computed with lattice QCD methods. This decay has not yet been measured. The knowledge of this width allows for th…
