Relativistic descriptions of few-body systems [PDF]
Few-Body Systems, 2010 A brief review of relativistic effects in few-body systems, of theoretical approaches, recent developments and applications is given. Manifestations of relativistic effects in the binding energies, in the electromagnetic form factors and in three-body ...

Hadronic few-body systems in chiral dynamics, -- Few-body systems in hadron physics -- [PDF]
Few-Body Systems, 2012 Hadronic composite states are introduced as few-body systems in hadron physics. The $\Lambda(1405)$ resonance is a good example of the hadronic few-body systems.

Critical stability of few-body systems [PDF]
, 2013 When a two-body system is bound by a zero-range interaction, the corresponding three-body system -- considered in a non-relativistic framework -- collapses, that is its binding energy is unbounded from below. In a paper by J.V. Lindesay and H.P. Noyes it

Electric dipole polarizability: from few- to many-body systems
EPJ Web of Conferences, 2016 We review the Lorentz integral transform coupled-cluster method for the calculation of the electric dipole polarizability. We benchmark our results with exact hyperspherical harmonics calculations for 4He and then we move to a heavier nucleus studying ...

Two-Body and Three-Body Contacts for Three Bosons in the Unitary Regime: Analytic Expressions and Limiting Forms [PDF]
Atoms, 2019 The two- and three-body contacts are central to a set of univeral relations between microscopic few-body physics within an ultracold Bose gas and its thermodynamical properties.

Few-Body Systems Consisting of Mesons [PDF]
Few-Body Systems, 2020 We present a work which is meant to inspire the few-body practitioners to venture into the study of new, more exotic, systems and to hadron physicists, working mostly on two-body problems, to move in the direction of studying related few-body systems.

Doubly heavy tetraquarks including one-pion exchange potential
Physics Letters B, 2023 Spectrum of the doubly heavy tetraquarks is studied in a constituent quark model including one-pion exchange (OPE) potential. Central and tensor forces induced by OPE between two light quarks are considered.

Fate of the topological susceptibility in two-color dense QCD
Journal of High Energy Physics, 2023 We explore the topological susceptibility at finite quark chemical potential and zero temperature in two-color QCD (QC2D) with two flavors. Through the Ward-Takahashi identities of QC2D, we find that the topological susceptibility in the vacuum solely ...
