Few-Body Systems (FBS2012)

JINR, Dubna, Russia

June 27 - 29, 2012


The International Workshop "Few-Body Systems", FBS-Dubna 2012, will be held on June 27 - 29, 2012, at the Bogoliubov Laboratory of Theoretical Physics, JINR, Dubna, Russia. The workshop program will cover various topics in physics of few-body systems including scattering theory, Coulombic few-body problems, few-body resonances, Efimov effect, Borromean binding, etc.

Few-body systems theory is dedicated to various quantum systems that might be considered consisting of several (say two, three, or four) elementary constituents. Depending on a particular situation and the energy range under consideration, the role of such constituents may be played by quarks, mesons, individual nucleons, nuclei or even by atoms and molecules. Smallness of the number of constituents in a system allows one to develop mathematically rigorous, exact and faithful approaches to its treatment, that do not require further simplifying physical assumptions or approximations. Due to their universality, the approaches based on the theory of few-body systems pave the way to successful solving various problems in nuclear physics, in physics of atoms and molecules, in quantum chemistry etc.

The purpose of the workshop is to bring together experts and young researchers working on few-body problems of nuclear physics, astrophysics, and physics of atomic and molecular collisions, for presenting their new results, identifying hot topics, and reporting on progress in methods and approaches.

Preliminary program of the workshop includes the following topics:

  • Scattering theory for quantum systems of several particles
  • Recent progress in theory of Coulombic few-body systems
  • Universal properties of few-body systems at ultra-low energies
  • Efimov and Thomas effects, Borromean binding, halo systems
  • Numerical approaches to solving few-body bound-state, resonance and scattering problems
