QCD sum rule analysis of Bottomonium ground states

Pallabi Parui, Sourodeep De, Ankit Kumar +1

The in-medium masses of the bottomonium ground states [$1S$ (${\rm Y}(1S),{\eta }_b$) and $1P$ (${\chi }_{b0},{\chi }_{b1}$)] are investigated in the magnetized vacuum (nuclear medium), using the QCD sum…
