Abstract

The difference between the strange quark antiquark amount in proton and neutron is studied. This difference is named isospin strange asymmetry, and has the origin in the small mass difference of the nucleon-hyperon-kaon uctuations. The amplitudes of these uctuations are determined by the Effective Chiral Theory(EChT). [ABSTRACT FROM AUTHOR]
