Precision measurement of the $J/ψ\toμ^+μ^-μ^+μ^-$ branching fraction and search for a new gauge boson $Z^{\prime}$ at BESIII
We present a precision measurement of the branching fraction of the rare decay $J/ψ\toμ^+μ^-μ^+μ^-$, and a search for a new gauge boson $Z^{\prime}$ that couples only to the second and third lepton generations, using a data sample of $(8998 \pm 39) \times 10^6$ $J/ψ$ events collected by the BESIII d
