To settle the question whether the growth with energy is universal for different hadronic total cross-sections, we present results from theoretical models for πp, and (pp,pp) total cross-sections. We show that present and planned experiments at LHC can differentiate between different models, all of which are consistent with presently available (lower energy) data . This study is also relevant for the analysis of those very high energy cosmic ray data which require reliable πp total cross-sections as seeds. A preliminary study of the total ππ cross-sections is also made.

“…For the case of pp, if the f /a mesons are responsible, their contribution can be normalized through the optical theorem by finding the contribution of the f /a trajectories to the γp total cross section which is given by [11,12]: σ tot (γp) = 0.0677s 0.0808 + 0.129s −0.4525 .…”

“…There is no data for the γK ± total cross section, so we must estimate it using Regge factorization using the pK ± scattering total cross section, which goes as [11,12]: In both of the above, the first term corresponds to the pomeron contribution. The second term is due to the ρ/ω/a/f trajectories.…”

We first suppose that low-energy hadron pair photoproduction reactions γ ( * ) γ ( * ) → hh are dominated by s-channel resonance contributions. Their normalization is then calculated by their correspondence with the Reggeon term in the Regge parametrization of the γh total cross sections. For the case of pp, we make use of the measured γp total cross section, and for the case of K + K − , we make use of the corresponding total cross section that is estimated using Regge factorization. For hadrons that have no such data, we can only provide rough estimation based on the additive quark rule. As an effective approach that is convenient and parameter-free, we adopt the Veneziano model in the simplest form. The model is only applicable to the region of low centre-of-mass energy. When the transverse momentum is large, perturbative QCD takes over, whereas in the Regge region, it is known that the Regge pole picture fails in photoproduction. Despite the shortcomings of the model, we find that the parameter-free amplitudes offer a sound description of the data at hand.

“…Donnachie and Landshoff [75] have employed the highly successful parametrizations of the hadron-hadron total cross sections [76], based on the exchange of an object we will refer to as the phenomenological Pomeron, along with an assumption of Vector-Meson Dominance (VMD) [48,77,78] and the additive quark model to describe vector-meson photoproduction. They used the e + e − decay width of the ρ 0 to estimate the γ * -ρ 0 -coupling.…”

The first five years of operation of the multi-purpose experiments ZEUS and H1 at the electron-proton storage ring facility HERA have opened a new era in the study of vector-meson production in high-energy photon-proton interactions. The high center-ofmass energy available at this unique accelerator complex allows investigations in hitherto unexplored kinematic regions, providing answers to long-standing questions concerning the energy-dependence of the ρ 0 , ω, φ, and J/ψ production cross sections. The excellent angular acceptance of these detectors, combined with that of specialized tagging detectors at small production angles, has permitted measurements of elastic and inelastic production processes for both quasi-real photons and those of virtuality exceeding the squared mass of the vector meson. This report provides a quantitative picture of the present status of these studies, comparing them to the extensive measurements in this field at lower energies and summarizing topical developments in theoretical work motivated by the new data.
