Starting from a bound-state model of weakly bound quarks for ($q bar{q}$) mesons, we derive a formalism for computing the production or decay of such mesons, whatever the value of their internal orbital angular momentum L. That approach appears as a natural generalization of the Brodsky-Lepage formalism (valid only for L=0) that has been widely used in recent years for the computation of exclusive processes in perturbative QCD. We here apply it to the production, in photon-photon collisions, of: i) tensor-meson pairs; ii) pseudotensor-meson pairs; iii) hybrid pairs made of a pion and a pseudotensor meson. The numerical results we obtain allow for some hope of experimentally identifying such pairs, in the charged channels, at high-energy e^+e^- colliders of the next generation, provided integrated luminosities as high as $approx 10^{40} cm^{-2}$ can be reached.

We discuss the pair production of charginos in collisions of polarized photons $gammagamma to tilde{chi}_i^+ tilde{chi}_i^-$, ($i=1,2$) and the subsequent leptonic decay of the lighter chargino $tilde{chi}_1^+ to tilde{chi}_1^0 e^+ u_e$ including th
e complete spin correlations. Analytical formulae are given for the polarization and the spin-spin correlations of the charginos. Since the production is a pure QED process the decay dynamics can be studied separately. For high energy photons from Compton backscattering of polarized laser pulses off polarized electron beams numerical results are presented for the cross section, the angular distribution and the forward-backward asymmetry of the decay positron. Finally we study the dependence on the gaugino mass parameter $M_1$ and on the sneutrino mass for a gaugino-like MSSM scenario.
We calculate the probability for dilepton production in central relativistic heavy ion collisions due to the gamma-gamma mechanism. This is a potential background to more interesting mechanisms. We find that this mechanism is negligible in the CERES
experiments. Generally, the contribution due to this mechanism is small in the central region, while it can be large for small invariant masses and forward or backward rapidities. A simple formula based on the equivalent photon approximation and applications to a possible scenario at RHIC are also given.
We study the decays of the pseudotensor mesons $[ pi_{2}(1670) , K_{2}(1770) , eta_{2}(1645) , eta_{2}(1870) ]$ interpreted as the ground-state nonet of $1^1 D_{2}$ $bar{q}q$ states using interaction Lagrangians which couple them to pseudoscalar, vec
tor, and tensor mesons. While the decays of $pi_2 (1670)$ and $K_2 (1770)$ can be well described, the decays of the isoscalar states $eta_2 (1645)$ and $eta_2 (1870)$ can be brought in agreement with experimental data only if the mixing angle between nonstrange and strange states is surprisingly large (about $-42^circ$, similar to the mixing in the pseudoscalar sector, in which the chiral anomaly is active). Such a large mixing angle is however at odd with all other conventional quark-antiquark nonets: if confirmed, a deeper study of its origin will be needed in the future. Moreover, the $bar{q}q$ assignment of pseudotensor states predicts that the ratio $[ eta_2 (1870) rightarrow a_2 (1320) pi]/[eta_2 (1870) rightarrow f_2 (1270) eta]$ is about $23.5$. This value is in agreement with Barberis et al., ($20.4 pm 6.6$), but disagrees with the recent reanalysis of Anisovich et al., ($1.7 pm 0.4$). Future experimental studies are necessary to understand this puzzle. If Anisovichs value shall be confirmed, a simple nonet of pseudoscalar mesons cannot be able to describe data (different assignments and/or additional state, such as an hybrid state, will be needed). In the end, we also evaluate the decays of a pseudoscalar glueball into the aforementioned conventional $bar{q}q$ states: a sizable decay into $K^ast_2 (1430) K$ and $a_2 (1230) pi$ together with a vanishing decay into pseudoscalar-vector pairs [such as $rho(770) pi$ and $K^ast (892) K$] are expected. This information can be helpful in future studies of glueballs at the ongoing BESIII and at the future PANDA experiments.
A vector-dominance two-photon exchange model is proposed to explain the recently observed production of $rho^0rho^0$ and $rho^0phi$ pairs in $e^+e^-$ annihilation at 10.58 GeV with the BaBar detector. All the observed features of the data --angular a
nd decay distributions, rates-- are in agreement with the model. Predictions are made for yet-unobserved final states.
A phenomenological study of the isolated photon production in high energy $pp$ and $pA$ collisions at RHIC and LHC energies is performed. Using the color dipole approach we investigate the production cross section differential in the transverse momen
tum of the photon considering three different phenomenological models for the universal dipole cross section. We also present the predictions for the rapidity dependence of the ratio of $pA$ to $pp$ cross sections. As a further test of the formalism, for different energies and photon rapidites we analyse the correlation function in azimuthal angle $Deltaphi$ between the photon and a forward pion. The characteristic double-peak structure of the correlation function around $Delta phisimeq pi$ observed previously for Drell-Yan pair production is found for isolated photon emitted into the forward rapidity region which can be tested by future experiments.
