The branching ratios and differential distributions for the four-leptonic decays B{sup −}→μ{sup +}μ{sup −}v̄{sub e}e{sup −}, B{sup −}→e{sup +}e{sup −}v̄{sub μ}μ{sup −}, and B{sup −}→μ{sup +}v̄{sub μ}μ{sup −}μ{sup −} are calculated within the Standard Model. The branching ratios for the rare decays B{sub d,s} → e{sup +}e{sup −}μ{sup +}μ{sup −} and B{sub d,s} → μ{sup +}μ{sup −}μ{sup +}μ{sup −} are estimated. Methods for testing the lepton universality in rare multileptonic decays of charged and neutral B mesons are proposed.
