It is well known that in effective Lagrangian formulations of photon-induced meson-production processes simply replacing standard Feynman-type $t$-channel exchanges by exchanges of Regge trajectories violates gauge invariance. We point out that the usual procedure for remedying this defect is flawed, and we show how to construct a contact current whose four-divergence cancels the gauge-invariance-

The isobar model EtaMAID is an online program of the MAID
collaboration in Mainz for calculations of observables, amplitudes
and multipoles for $\eta$ and $\eta\prime$ photo- and electroproduction on the nucleon. It was introduced in 2001 and
updated in 2003. Now we will present a new update EtaMAID2016,
taking into account very recent high-precision data of differential
cross sections for $p

Assuming that the $f_2(1270)$, $f_2(1525)$, $a_2(1320)$, and $K^\star_2 (1430)$ resonances are dynamically generated states from vector-meson–vector-meson interactions in the $s$-wave with spin $S = 2$, we study the $\gamma p \to f_2(1270) p,\ f_2(1525) p,\ a^0_2(1320) p$, and $\gamma p \to K^\star_2(1430) \Lambda (\Sigma)$ reactions. These reactions proceed in the following way: the incoming

We shall present nuclear cross section for $AA \to AA V$ and $AA \to AA VV$ processes
where $A$ means a nucleus (lead or gold) and $V$ denotes $\rho^0$ or $J/\psi$ vector meson.
Analysis is done in the impact parameter space equivalent photon approximation.
This approach allows to consider a particular process taking into account
distance between colliding nuclei.
We consider both ultraperi
