The amplitude of lepton-pair production in relativistic ion collisions beyond the perturbative theory
A. N. Sissakian, A. V. Tarasov, H. T. Torosyan +1
We investigate the structure of some first terms of Watson series representing the amplitude of lepton-pair production in the ion collisions. It is shown that infrared instabilitie…
The pair production in relativistic ions collision and its correspondence to electron scattering
A. N. Sissakian, A. V. Tarasov, H. T. Torosyan +1
It is shown that the processes of electron(positron) scattering and pair production in the Coulomb fields of two relativistic ions, can be expressed through the amplitudes…
NLO QCD procedure of the SIDIS data analysis with respect to light quark polarized sea
A. N. Sissakian, O. Yu. Shevchenko, O. N. Ivanov
The semi-inclusive deep inelastic scattering (SIDIS) process is considered. It is proposed a theoretical procedure allowing the direct extraction from the SIDIS data of the first m…
Separation of variables and Lie algebra contractions. Applications to special functions
George Pogosyan, Alexey Sissakian, Pavel Winternitz
A review is given of some recently obtained results on analytic contractions of Lie algebras and Lie groups and their applications to special function theory.
Topological charge and topological susceptibility in connection with translation and gauge invariance
A. M. Kotzinian, O. Yu. Shevchenko, A. N. Sissakian
It is shown that the evaluation of the expectation value (EV) of topological charge density over -vacuum is reduced to investigation of the Chern-Simons term EV. An equation for…
Phenomenology of Very High Multiplicity Hadron Processes
J. Manjavidze, A. Sissakian
We discuss the possibility to suppress the nonperturbative effects if the very high multiplicity hadron final states are chosen. The theoretical uncertainties and possible experime…
