DEPARTMENT OF THEORETICAL PHYSICS

RESEARCH OVERVIEW

---

Research activities of the Department cover a wide range of topics:

Nuclear Physics:

• algebraic models for nuclear structure,
• elastic scattering of K⁺ on nuclei,
• electromagnetic and weak meson exchange currents,
• electroproduction of hypernuclei and deeply bound L single-particle states,
• few-nucleon systems both in v/c-expansion approach and in covariant framework,
• low lying states of p^-, K^- and S exotic atoms,
• large-basis shell-model calculations for light nuclei and few-nucleon systems,
• mesonic nad nonmesonic decays of light hypernuclei,
• relativistic bound states in Bethe-Salpeter and spectator quasipotential description,

Particle Physics:

• dynamical electroweak symmetry breaking,
• effective chiral model for low energy meson-baryon interaction,
• electroproduction of K⁺ on protons (isobaric and Regge models),
• low-energy effective chromodynamics,
• processes with high transverse momenta at relativistic energies,
• separable model for K⁺ N scattering amplitude,
• solution of Schwinger-Dyson equation in Minkowski space,
• study of macroscopic quantum phases of deconfined QCD matter at finite density,

Mathematical Physics:
