New source of charge-symmetry violation in the nucleon-nucleon system

Journal Article · · Phys. Rev. D; (United States)
Within the framework of the cloudy bag model we show that the small difference of up- and down-quark masses leads to a small increase in the ..pi../sup 0/nn coupling constant relative to ..pi../sup 0/pp. There may be many experimental consequences of this observation but, as an example, Vertical Bara/sub n/nVertical Bar-Vertical Bara/sub p/pVertical Barapprox. =0.3 fm because of this effect.
