Decay of Resonaces in Strong Magnetic Field

Original · EN

We suggest that decay properties (branching ratios) of hadronic resonances may become modified in strong external magnetic field. The behavior of K± *, K⁰* vector mesons as well as Λ*(1520) and Ξ⁰* baryonic states is considered in static fields 10¹³-10¹⁵ T. In particular, n=0 Landau level energy increase of charged particles in the external magnetic field, and the interaction of hadron magnetic moments with the field is taken into account. We suggest that enhanced yield of dileptons and photons from ρ⁰(770) mesons may occur if strong decay channel ρ⁰ → π+π- is significantly suppressed. CP - violating π+π- decays of pseudoscalar ηc and η(547) mesons in the magnetic field are discussed, and superpositions of quarkonium states ηc,b and χc,b(nP) with Ψ(nS), Υ(nS) mesons in the external field are considered.
