Strange vector form factors of the nucleon in the SU(3) chiral quark-soliton model with the proper kaonic cloud
چکیده
Abstract The strange vector form factors are evaluated in the range between Q2 = 0 and Q2 = 1 GeV in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational 1/Nc and ms corrections are taken into account up to linear order. Taking care of a proper Yukawa-tail of the kaonic cloud, we get 〈r2〉Sachs s = −0.095 fm and μs = −0.68 μN . The results are compared with several different models. PACS: 12.40.-y, 14.20.Dh
