Let R and B be disjoint point sets such that R âˆª B is in general position. We say that B is enclosed by R if there is a simple polygon P with vertex set R such that all the elements in B belong toâ€¦ (More)

If Tn(x, y) is the Tutte polynomial of the complete graph Kn, we have the equality Tn+1(1, 0) = Tn(2, 0). This has an almost trivial proof with the right combinatorial interpretation of Tn(1, 0) andâ€¦ (More)

The information about sizes and nuclear density distributions in unstable (radioactive) nuclei is usually extracted from the data on interaction of radioactive nuclear beams with a nuclear target. Weâ€¦ (More)

We consider the possible contribution of Odderon (Reggeon with Î±Odd(0) âˆ¼ 1 and negative signature) exchange to the differences in the total cross sections of particle and antiparticle, to the ratiosâ€¦ (More)

In the framework of Quark-Gluon String Model we calculate the inclusive spectra of secondaries produced in d+Au collisions at intermediate (CERN SPS) and at much higher (RHIC) energies. The resultsâ€¦ (More)

The RHIC data on charm production are compared with the kT -factorization approach predictions, both standard NLO QCD and FONLL. The calculated results underestimate the STAR Collaboration data. Theâ€¦ (More)

We consider the phenomenological implications of the assumption that baryons are systems of three quarks connected through gluon string junction. The transfer of baryon number in rapidity space dueâ€¦ (More)
