Abstract

A search for the non-resonant decays B0s → 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 be B(B0s → μ+ μ− μ+ μ−) < 2.5×10^−9, B(B0 → μ+ μ− μ+ μ−) < 6.9×10^−10.
