We use dispersive techniques to address the behavior of the pion form factor as Q2 → ∞ and Q2 → 0. We perform the matching with the constraints of perturbative QCD and chiral perturbation theory in th...
Reanalysis of Proton Form Factor Ratio Data at $\mathbf{Q^2 =}$ 4.0, 4.8, and 5.6 GeV$\mathbf{^2}$ 。
Electromagnetic form factor of pion from N_f=2+1 dynamical flavor QCD 。
Implications of the recent high statistics determination of the pion electromagnetic form factor in the timelike region 。
The transverse charge density in the pion can be represented as a dispersion integral of the imag-inary part of the pion form factor in the timelike region.
The transverse charge density in the pion can be represented as a dispersion integral of the imag-inary part of the pion form factor in the timelike region.
The KLOE experiment at the φ-factory DAΦNE has measured the pion form factor in the range between 0.1at √s= 1 GeV with a photon emitted at large polar angles in th...
The high intensity and high energy antiproton beams which will be produced at FAIR open the possibility to determine time-like electromagnetic form factors in a wide kinematical range, through the a...
We study the reaction e+e- --> e+e- eta_c, eta_c --> K_S K+- pi-+ and obtain eta_c mass and width values 2982.2+-0.4+-1.6 MeV/c^2 and 31.7+-1.2+-0.8 MeV, respectively. We find Gamma(eta_c --> gamma ga...
The electromagnetic probe is an excellent tool to investigate the structure of the nucleon. The nearly 4π detector PANDA, will allow to make a precise determination of the electromagnetic form factors...
