Summary:The extraordinary strong magnetic field generated in ultrarelativistic heavy ion collisions makes it possible to investigate many novel effects in the hot QCD matter, and a direct probe of it thus becomes an urgent task in the field. Here we report a new way to probe it, where the leptonic invariant mass distribution of Z 0 boson will be modified in the presence of the magnetic field due to the Lorentz force on the lepton pairs from the decay of Z 0 boson. It is found that the magnetic field can decrease the mean value of Z 0 leptonic invariant mass and increase its width, and both shifts approximately depend on the integral of the magnetic field over its time duration quadratically.
