Journal of High Energy Physics, 2022 We perform a re-analysis of Belle data for the transverse Λ and Λ ¯ $$ \overline{\Lambda} $$ polarization in e + e − annihilation processes within a transverse momentum dependent (TMD) factorization approach.

Novel Aspects of QCD in Leptoproduction
, 2004 I review several topics in electroproduction which test fundamental aspects of QCD. These include the role of final-state interactions in producing diffractive leptoproduction processes, the shadowing of nuclear structure functions, and target-spin ...

Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Journal of High Energy PhysicsWe investigate the inclusive production of double quarkonia (J/ψ, ψ(2S), Υ mesons) in polarized hadron-hadron collisions, considering the kinematic configuration where the transverse momentum of each pair of bound states is much smaller than its ...

Gauge-invariant quark and gluon fields in QCD: dynamics, topology, and the Gribov ambiguity
, 2001 We review the implementation, in a temporal-gauge formulation of QCD, of the non-Abelian Gauss's law and the construction of gauge-invariant gauge and matter fields.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Full treatment of the thrust distribution in single inclusive e + e − → h X processes
Journal of High Energy Physics, 2023 Extending the transverse momentum dependent factorization to thrust dependent observables entails a series of difficulties, ultimately associated to the behavior of soft radiation.

Higher Twist in Electroproduction: Flavor Non-Singlet QCD Evolution
, 2013 We present results for the one loop anomalous dimension matrix of flavor non-singlet twist-4 operators of lowest spin that contribute to the leading moment of the $F_2$ structure function in deep inelastic electron-nucleon scattering.

Large Lorentz Scalar and Vector Potentials in Nuclei [PDF]
, 1999 In nonrelativistic models of nuclei, the underlying mass scales of low-energy quantum chromodynamics (QCD) are largely hidden. In contrast, the covariant formulations used in relativistic phenomenology manifest the QCD scales in nuclei through large ...

Measuring the Quantum State of Dark Matter
Annalen der Physik, Volume 536, Issue 1, January 2024.It is demonstrated how the time series obtained from searches for ultralight bosonic dark matter, such as the axion, can be used to determine whether it is in a coherent or incoherent quantum state. Abstract It is shown how the time series obtained from searches for ultralight bosonic dark matter (DM), such as the axion, can be used to determine ...
