Modification of meson properties in the vicinty of nuclei

We suggest that modification of meson properties (lifetimes and branching ratios) can occur due to the interaction of constituent quark magnetic moments with strong magnetic fields present in the close vicinity of nuclei. A superposition of (J =0) and (J =1, mz =0) particle-antiparticle quantum states (as observed for ortho-Positronium) may occur also in the case of quarkonium states J/Ψ, ηc ϒ, ηb in heavy ion collisions. We speculate on possible modification of η(548) meson properties (related to C parity and CP violation) in strong magnetic fields which are present in the vicinity of nuclei
