Motivated by the first measured Δ+→ p e+ e− decay by the HADES Collaboration, electromagnetic Dalitz baryon decays from the spin 3 2 decuplet (T 10) to the spin 1 2 octet (T 8) baryons are investigated by using the SU (3) flavor symmetry/breaking in this paper. All decay amplitudes of T 10→ T 8 ℓ+ ℓ−(ℓ= e, μ) electromagnetic Dalitz decays could be related by the SU (3) flavor symmetry/breaking, so the amplitudes can be obtained by the measured branching ratio of Δ+→ p e+ e− decay from the HADES Collaboration. The branching ratios, the lepton flavor universality, and the ratios B (T 10→ T 8 ℓ+ ℓ−) B (T 10→ T 8 γ) are predicted by the relevant experimental data. T 10→ T 8 μ+ μ− electromagnetic Dalitz decays are studied for the first time. All predicted B (T 10→ T 8 ℓ+ ℓ−) except B (Ξ⁎ 0→ Ξ 0 μ+ μ−) and B (Ξ⁎−→ Ξ− μ+ μ−) are on the order of O (10− 5− 10− 7), and these decays could be observed and could be used to test the SU (3) flavor symmetry/breaking approach in the electromagnetic Dalitz decays by HADES, PANDA, BESIII, and other experiments in the near future.
