Carathéodory bounds for integer cones

We provide analogues of Carathéodory's theorem for integer cones and apply our bounds to integer programming and to the cutting stock problem. In particular, we provide an NP certificate for the latter, whose existence has not been known so far.     

Hadron structure and specific features of the process of multiple generation at ultrahigh energies

An attempt to correlate the data on multiple production both in the accelerator region and in the region of ultrahigh energies within a unique picture, based on the quark-gluon model of the hadron, suggests the conclusion that quarks are composite objects. In accordance with this conclusion surprising effects, recently discovered at ultrahigh energies, manifest themselves owing to the transition over the energy threshold caused by the intrinsic structure of quarks. The objects arising in this energy region, quark clusters, are analysed within the thermodynamical model the authors have proposed earlier. The estimates obtained do not contradict the experiment.

An estimation of high-momentum quark component characteristics in nuclei

The colour fluctuations of nuclear nucleon are shown to be a suitable theoretical mechanism to realize cumulative deep inelastic lepton-nucleus scattering. Based on this mechanism, the prediction for nuclear structure function depending on the momentum distribution of gluons in nucleon is obtained.

On a present status of the gathering model for cumulative meson production

Physical grounds of the “gathering” model are discussed. It is shown that the “gathering” of nucleons in a collective interaction is a direct consequence of the behaviour of colour forces at large distances. An analytical variant of the model is presented which allows a large simplification of the calculation procedure. The results obtained are compared with the data onπ- andK-meson cumulative production. The model applicability for relativistic nucleus-nucleus collisions is discussed.
