QUARK-ANTIQUARK ONE GLUON EXCHANGE POTENTIAL AND EFFECTIVE NUCLEON-ANTINUCLEON POTENTIAL

  • In this paper, the quark-antiquark one gluon exchange potential corresponding to the annihilation channels is calculated to the order of p2/m2 by means of Fierz reordering transformation. The nucleon-antinucleon effective potential obtained from one gluon exchange potential has a strong attraction at a short distance as expected in the meson-exchange theory.

QUARK-ANTIQUARK ONE GLUON EXCHANGE POTENTIAL AND EFFECTIVE NUCLEON-ANTINUCLEON POTENTIAL

    Corresponding author: SU Jun-Chan,

Abstract: In this paper, the quark-antiquark one gluon exchange potential corresponding to the annihilation channels is calculated to the order of p2/m2 by means of Fierz reordering transformation. The nucleon-antinucleon effective potential obtained from one gluon exchange potential has a strong attraction at a short distance as expected in the meson-exchange theory.
