Electromagnetic form factors of the ρ meson in light cone QCD sum rules
نویسنده
چکیده
We investigate the electromagnetic form factors of the ρ meson in light cone QCD sum rules. We find that the ratio of the magnetic and charge form factors is larger than two at all values of Q2, (Q2 ≥ 0.5 GeV 2). The values of the individual form factors at fixed values of Q2 predicted by the light cone QCD sum rules are quite different compared to the results of other approaches. These results can be checked in future, when more precise data on ρ meson form factors is available. PACS numbers: 12.38.Lg, 13.40.Gp e-mail: [email protected] e-mail: [email protected]

Electromagnetic form-factor of the π meson with light-cone QCD sum rules
In this article, we calculate the electromagnetic form-factor of the π meson with the light-cone QCD sum rules. The numerical value fp(0) = 0.999±0.001 is in excellent agreement with the experimental data (extrapolated to the limit of zero momentum transfer). For large momentum transfers, the values from the two sum rules are all comparable with the experimental data and theoretical estimations...
متن کاملUse and Misuse of QCD Sum Rules in Heavy-to-light Transitions: the Decay B → ρeν Reexamined
The existing calculations of the form factors describing the decay B → ρeν from QCD sum rules have yielded conflicting results at small values of the invariant mass squared of the lepton pair. We demonstrate that the disagreement originates from the failure of the short-distance expansion to describe the ρ meson distribution amplitude in the region where almost the whole momentum is carried by ...

The magnetic moment μ of the ρ meson is studied in QCD light cone sum rules, and it is found that μ = (2.3 ± 0.5). A comparison of our result on the magnetic moment of the ρ meson with the predictions of the other approaches, is presented.
