【 摘 要 】

The influence of static magnetic field on decays φ (1020) KK, ϒ (4s)→ BB, and Σ±∗→ π±is discussed. In particular, we estimate how much the ratio of decay widths Γ(K+K-)/Γ(K0K0) and Γ(B+B-)/Γ(B0B0) can be modified by magnetic fields of strength B ≈ 1014 T created in relativistic collisions of heavy nuclei at LHC and RHIC colliders. Due to interaction of charged K and B mesons with the magnetic field, branching ratios for K+K- and B+B- decays of φ (1020) and ϒ (4s) completely closed. We study also the influence of magnetic field on strong decay Σ±∗(1385) → + π±.
