Form factors for timelike momentum transfers, determined by hadron-antihadron formation in e+e- annihilation, provide information about spin correlations between the hadron pair produced, information complementary to that provided by spacelike form factors determined by electron scattering from hadronic targets. Timelike form factors at large momentum transfers have only been so far measured...

The NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient trigger for decays into electrons in 2007. The kaon beam represents a source of tagged neutral pion decays in vacuum. A measurement of the electromagnetic transition form factor slope of the neutral pion in the time-like region from ~1 million fully reconstructed pi0 Dalitz decay is presented.

Based on the large samples of J/ψ and ψ(2s) events accumulated at the BESIII detector, the recent results on baryon spectrosocopy will be presented, including the PWA of ψ(2S)-->p pbar pi0, p pbar eta. Also the perspectives on the baryon spectroscopy at BESIII will be discussed.

Hyperon production in e+e- annihilation provides a clean laboratory for the production of baryons and strangeness in hadronization, and can provide insight into the structure of different hyperons by comparing their production rates. Using 52 pb-1, 805 pb-1, and 586 pb-1 of e+e- annihilation data taken at the psi(2S), psi(3770), and psi(4160) resonances, respectively, with the CLEO-c detector,...

We discuss our dynamical coupled-channels (DCC) model for neutrino-nucleon interaction in the resonance region where single- and double-pion productions are dominant. Our DCC model is based on meson-exchange non-resonant mechanisms, and excitaions of nucleon resonances. By solving a set of coupled-channels scattering equation, we obtain amplitudes for meson productions such as pi N, pi pi N,...

The Siegert's theorem states that in a g* N -> N* transition, where N and N* are respectively the nucleon and a nucleon resonance, the electric amplitude, E (defined by the transverse amplitudes) and the scalar amplitude, S, are related in the pseudo-threshold limit by E ~ w/q*S, where w and q are the photon energy and momentum. The pseudo-threshold limit is the limit where q ->0, when the...

The Charmed baryon is a unique system, considered as a bound state of a charm quark and a light di-quark due to the suppression of the color spin interaction of the heavy charm quark. Belle experiment has led the charmed baryon spectroscopy with the world highest integrated luminosity $e^+e^-$ collision data provided by KEKB accelerator. In this talk, we present the latest results on charmed...

The concept of diquark degrees of freedom is expected to be essential to describe hadrons in the excited states as well as in the ground states. Since the spin-dependent interaction between quarks is inversely proportional to the masses of the quarks, the extraction of a light-qq correlation from baryons with one heavy quark is easier than from those with only light flavors. J-PARC E50...
