Strange mesonic transition form factor

PDF Version Also Available for Download.

Description

The strange-quark vector current {rho}-to-{pi} meson transition form factor is computed at one-loop order using strange meson intermediate states. A comparison is made with a {phi}-meson dominance model estimate. They find that one-loop contributions are comparable in magnitude to those predicted by {phi}-meson dominance. It is possible that the one-loop contribution can make the matrix element as large as those of the electromagnetic current mediating vector meson radiative decays. However, due to the quadratic dependence of the one-loop results on the hadronic form factor cut-off mass, a large uncertainty in the estimate of the loops is unavoidable. These results indicate ... continued below

Description

The strange-quark vector current {rho}-to-{pi} meson transition form factor is computed at one-loop order using strange meson intermediate states. A comparison is made with a {phi}-meson dominance model estimate. They find that one-loop contributions are comparable in magnitude to those predicted by {phi}-meson dominance. It is possible that the one-loop contribution can make the matrix element as large as those of the electromagnetic current mediating vector meson radiative decays. However, due to the quadratic dependence of the one-loop results on the hadronic form factor cut-off mass, a large uncertainty in the estimate of the loops is unavoidable. These results indicate that non-nucleonic strange quarks could contribute appreciably in moderate-{vert_bar}Q{sup 2}{vert_bar} parity-violating electron-nucleus scattering measurements aimed at probing the strange-quark content of the nucleon.
