Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Signals of the QCD Phase Transition in the Heavens [PDF]
, 2007 The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Axion phenomenology and lattice QCD [PDF]
, 2016 The properties of the QCD axion can be studied from the dependence of strong interactions on the θ -parameter. We present a study of the moments of the topological charge for temperatures up to around 600 MeV, obtained by lattice QCD simulations with 2+1

Event generation with exponential scaling in multiplicity using AmpliCol
Journal of High Energy PhysicsEfficient generation of LHC events is hindered by the rapidly rising cost of evaluating QCD matrix elements with increasing multiplicity. We build on a recently proposed two-step strategy in which unweighted events are first generated using the leading ...

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.

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 ...

Infrared behaviour and renormalization scheme invariance of QCD observables [PDF]
, 2006 In this thesis we study the infrared (IR) behaviour of QCD observables, and solutions to the problem of renormalization scheme dependence. We investigate the IR behaviour of all-orders leading-b renormalon resummations for certain Euclidean observables ...

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.

Effective theories of finite volume QCD [PDF]
, 2008 Finite volume QCD close to the chiral limit cannot be described by chiral Perturbation Theory using the usual p-expansion when the correlation length of pions becomes larger than the size of the box.
