Using the Quark-Gluon Strings Model -- combined with Regge phenomenology -- we perform a comparative analysis of $Lambda$, $Sigma^0$, $Lambda(1520)$ and $Theta^+$ production in binary reactions induced by photon, pion and proton beams on the nucleon. We find that the existing experimental data on the $gamma p to K^+ Lambda$ differential and total cross sections can be described very well by the model for photon energies $1 - 16$ GeV and $-t < 2$ GeV$^2$ assuming a dominant contribution of the $K^*$ Regge trajectory. Moreover, using the same parameters we also reproduce the total $gamma p to K^+ Sigma^0$ and $gamma p to K^+ Lambda(1520)$ cross sections suggesting a universality of the Regge model. In order to check the consistency of the approach we evaluate the differential and total cross sections for the reaction $pi^- p to K^0 Lambda$ which is also found to be dominated by the $K^*$ Regge trajectory. Using the apparent universality of the Regge model we extend our scheme to the analysis of the binary reactions $gamma p to bar{K}^0 Theta^+$, $pi^- p to K^- Theta^+$ and $pp to Sigma^+ Theta^+$ as well as the exclusive and inclusive $Theta^+$ production in the reactions $pp to p bar{K}^0 Theta^+$ and $pp to Theta^+ X$. Our detailed studies demonstrate that $Theta^+$ production does not follow the universality principle thus suggesting an essentially different internal structure of the exotic baryon relative to conventional hyperons or hyperon resonances.
The cross sections for the reactions pp -> p Lambda^0K^+ and pn -> n Lambda^0K^+ are calculated near threshold of the final states. The theoretical ratio of the cross sections R = sigma(pn -> n Lambda^0K^+)/ sigma(pp ->pLambda^0K^+) = 3 shows the e
Polarization properties of strange baryons produced in pp reactions, p + p -> p + Lambda^0 + K^+ and p + p -> p + Sigma^0 + K^$, near thresholds of the final states (p Lambda^0 K^+) and (p Sigma^0 K^+) are analysed relative to polarizations of collid
The $Lambda$-hypernucleus production by $A(p, pK^+)_{Lambda}B$ reactions is investigated within the framework of the distorted wave impulse approximation(DWIA). The amplitude for the elementary process is evaluated in a fully covariant two-nucleon mo
Differential cross sections and photon-beam asymmetries for the gamma p -> K+ Lambda(1520) reaction have been measured with linearly polarized photon beams at energies from the threshold to 2.4 GeV at 0.6<cos(theta)<1. A new bump structure was found
The $phi$-$Lambda(1520)$ interference effect in the $gamma pto K^+K^-p$ reaction has been measured for the first time in the energy range from 1.673 to 2.173 GeV. The relative phases between $phi$ and $Lambda(1520)$ production amplitudes were obtaine
