Isotensor Axial Polarizability and Lattice QCD Input for Nuclear Double-
Physical Review Letters, 2017 The potential importance of short-distance nuclear effects in double-β decay is assessed using a lattice QCD calculation of the nn→pp transition and effective field theory methods.

Process-Independent Effective Coupling: From QCD Green’s Functions to Phenomenology [PDF]
Few-body systems, 2018 This article reports on a very recent proposal for a new type of process-independent QCD effective charge (Binosi et al. in Phys Rev D 96(5):054026, 2017.

QCD at non-zero density and phenomenology [PDF]
Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2019 In the last few years, numerical simulations of QCD on the lattice have reached a new level of accuracy. A wide range of thermodynamic observables is now available in the continuum limit and for physical quark masses.

Axion phenomenology and θ-dependence from N f = 2 + 1 lattice QCD [PDF]
Journal of High Energy Physics, 2016 We investigate the topological properties of Nf = 2 + 1 QCD with physical quark masses, both at zero and finite temperature. We adopt stout improved staggered fermions and explore a range of lattice spacings a ∼ 0.05 − 0.12 fm.

QCD phenomenology with infrared finite SDE solutions [PDF]
, 2010 Recent progress in the solution of Schwinger-Dyson equations (SDE), as well as lattice simulation of pure glue QCD, indicate that the gluon propagator and coupling constant are infrared (IR) finite. We discuss how this non-perturbative information can be

Phenomenology on the QCD dipole picture revisited [PDF]
, 2003 We perform an adjust to the most recent structure function data, considering the QCD dipole picture applied to ep scattering. The structure function F2 at small x and intermediate Q2 can be described by the model containing an economical number of free ...

Recent progress on QCD inputs for axion phenomenology [PDF]
, 2016 The properties of the QCD axion are strictly related to the dependence of strong interactions on the topological parameter theta. We present a determination of the topological properties of QCD for temperatures up to around 600 MeV, obtained by lattice ...

QCD phenomenology of static sources and gluonic excitations at short distances [PDF]
, 2004 New lattice data for the ${\ensuremath{\Pi}}_{u}$ and ${\ensuremath{\Sigma}}_{u}^{\ensuremath{-}}$ potentials at short distances are presented. We compare perturbation theory to the lower static hybrid potentials and find good agreement at short ...

QCD Phenomenology and Light-Front Wavefunctions [PDF]
, 2001 A natural calculus for describing the bound-state structure of relativistic composite systems in quantum field theory is the light-front Fock expansion which encodes the properties of a hadrons in terms of a set of frame-independent n-particle ...
