Cover Story: Gluons are massless at the level of the fundamental QCD Lagrangian, but acquire an effective mass through the action of the celebrated Schwinger mechanism. The activation of this mechanism hinges on the formation of composite massless poles, which modify the analytic structure of the fundamental vertices of the theory, and induce smoking gun displacements in the corresponding Ward identities. In this article, we elucidate the key notions connected with this special dynamical scenario, placing particular emphasis on the synergy between continuum Schwinger function methods and lattice simulations, and highlighting recent advances that corroborate the action of the Schwinger mechanism in QCD.

This paper review the modelling efforts regarding Generalised Parton Distributions (GPDs) using continuum techniques relying on Dyson–Schwinger and Bethe–Salpeter equations. The definition and main properties of the GPDs are first recalle...

We review recent studies of vortical motion and the resulting polarization of Λ hyperons in heavy-ion collisions at NICA energies, in particular, within the model of three-fluid dynamics (3FD). This includes predictions of the global Λ...

The Invariance of Inelastic Overlap Function

  • Sergey Mikhailovich Troshin and
  • Nikolai Evgenjevich Tyurin

3 February 2023

In this study, we consider the symmetry property of the inelastic overlap function and its relation to the reflective scattering mode appearance. This symmetry property disfavors an exclusion of one of the scattering modes—the reflective mode&m...

  • Burkhard Kämpfer

2 February 2023

In this paper, the impact of core mass on the compact/neutron-star mass-radius relation is studied. Besides the mass, the core is parameterized by its radius and surface pressure, which supports the outside one-component Standard Model (SM) matter. T...

The description of the stellar interior of compact stars remains as a big challenge for the nuclear astrophysics community. The consolidated knowledge is restricted to density regions around the saturation of hadronic matter ρ0=2.8×1014gcm&...

Laser-induced nuclear reactions in ultra-dense hydrogen H(0) (review in Physica Scripta 2019) create mesons (kaons and pions). These mesons decay mainly to muons. The muons created are useful (patented source) for the muon-induced fusion process. The...
