A search for the non-resonant decays Bs 0 → μ+μ−μ+μ− and B0 → μ+μ−μ+μ− is presented. The measurement is performed using the full Run 1 data set collected in proton-proton collisions by the LHCb experiment at the LHC. The data correspond to integrated luminosities of 1 and 2 fb−1 collected at centre-of-mass energies of 7 and 8 TeV, respectively. No signal is observed and upper limits on the branching fractions of the non-resonant decays at 95% confidence level are determined to beℬ(Bs0→μ+μ−μ+μ−)<2.5×10−9 B(B0 → µ+µ−µ+µ −) < 6.9 × 10−10
