Definite evidence for physically incomprehensible inequality $\sigma_{tot}(e^+e^- \to n \bar n) > \sigma_{tot}(e^+e^- \to p \bar p)$

Abstract

Though the neutron mass is larger than the proton mass and obviously one expects in $e^+e^-$ annihilation a creation of more $p \bar p$ pairs in comparison with $n \bar n$ at the same energy, just the opposite inequality for the corresponding total cross sections $\sigma_{tot}(e^+e^- \to n \bar n) > \sigma_{tot}(e^+e^- \to p \bar p)$ has been revealed in the analysis of only the present time existing proton electromagnetic form factors data by the unitary and analytic approach.
