Hyperon resonances are becoming an extremely useful tool allowing the study of the properties of hadronic fireballs made in heavy ion collisions. Their yield, compared to stable particles with the same quark composition, depends on hadronization conditions. The resonance’s short lifetime makes them ideal probes of the fireball chemical freeze-out mechanisms. An analysis of resonance abundance i...

We review a recent global analysis of inclusive single-charged-hadron production in high-energy colliding-beam experiments, which is performed at nextto-leading order (NLO) in the parton model of quantum chromodynamics endowed with nonperturbative fragmentation functions (FFs). Comparisons of pp data from CERN SppS and the Fermilab Tevatron and γp data from DESY HERA with the corresponding NLO ...

We develop a relativistic covariant and unitary description of the pion-nucleon interaction in a hadron-exchange model. The model is based on the solution of a dimensionally reduced (quasipotential) Bethe-Salpeter equation for the partial-wave off-shell πN scattering amplitudes with the potential consisting of the field-theoretical sand u-channel nucleon, Roper, Delta, D13, S11 exchanges, and t...

Abstract Novel considerations are presented on the physics, apparatus and accelerator designs for a future, luminous, energy frontier electron-hadron ( eh ) scattering experiment at LHC in thirties which key physics topics their relation to hadron-hadron HL-LHC programme discussed. Demands derived set by these design of LHeC detector, corresponding update is described. Optimisations design, esp...

We argue that the extended Nambu-Jona-Lasinio model which introduces four-quark interactions to describe hadron physics at low energies can be confronted with fundamental quantum chromodynamics by means of spectral sum rules. While there arise rather restrictive bounds on the strength of the effective four-quark interaction in the vector channel, introduction of the four-quark interaction in th...

The closed relativistic string carrying two point-like masses is considered as the model of a glueball with two constituent gluons. Here the gluon-gluon interaction is simulated by a pair of strings. For this system exact solutions of classical equations of motions are obtained. They describe rotational states of the string resulting in the set of quasilinear Regge trajectories with different b...

We evaluate the impact of recent developments in hadron phenomenology on extracting possible fundamental tensor interactions beyond the standard model. We show that a novel class of observables, including the chiral-odd generalized parton distributions, and the transversity parton distribution function can contribute to the constraints on this quantity. Experimental extractions of the tensor ha...

This talk summarizes recent QCD results from HERA, the Tevatron Collider and Tevatron xed target experiments.

The interpretation of extensive air shower (EAS) measurements often requires the comparison with EAS simulations based on high-energy hadronic interaction models. These interaction models have to extrapolate into kinematical regions and energy ranges beyond the limit of present accelerators. Therefore, it is necessary to test whether these models are able to describe the EAS development in a co...
