The two-photon-exchange (TPE) contribution in $ep\rightarrow ep\pi ^0$ with $W=M_{\Delta}$ and small $Q^2$ is calculated and its corrections to the ratios of electromagnetic transition form factors $R_{EM} = E_{1+}^{(3/2)}/M_{1+}^{(3/2)} $ and $R_{SM

We study the near-threshold incoherent $\ensuremath{\phi}$ photoproduction on the deuteron based on a model of $\ensuremath{\gamma}N\ensuremath{\rightarrow}\ensuremath{\phi}N$, consisting of Pomeron, $(\ensuremath{\pi},\ensuremath{\eta})$ exchanges,

Some of the featured results of the Dubna-Mainz-Taipei (DMT) dynamical model for $\pi N$ scattering and $\pi^0$ electromagnetic production are summarized. These include results for threshold $\pi^0$ production, deformation of $\Delta(1232)$, and the

We reexamine, within the nonrelativistic constituent quark model (NRCQM), a recent claim that the current data on the strangeness form factors indicates that the uuds\bar{s} component in the proton is such that the uuds subsystem has the mixed spatia

We study whether the nonmonotonic behavior found in the differential cross section of the phi-meson photoproduction near threshold can be described by a resonance. Namely, we add a resonance to a model consisting of Pomeron and (pi,eta) exchange by f

A meson-exchange πN model, previously constructed using three-dimensional reduction scheme of the Bethe-Salpeter equation for a model Lagrangian involving π , η , N , Δ, ρ , and σ fields, is extended to energies up to 2 GeV by including the ηN

We review the description of the lowest-energy nucleon excitation -- the $\Delta$(1232)-resonance. Much of the recent experimental effort has been focused on the precision measurements of the nucleon-to-$\Delta$ transition by means of electromagnetic

The Dubna-Mainz-Taipei (DMT) dynamical model for pion electromagnetic production, which describe well the existing data from threshold up to 1 GeV photon lab energy is presented and used to analyze recent data in the Δ region. We find that within DM

The \gamma p \to \gamma \eta p reaction in the S11(1535) resonance region is investigated as a method to access the S11(1535) magnetic dipole moment. To study the feasibility, we perform calculations of the \gamma p \to \gamma \eta p process within a
