Phenomenology from lattice QCD [PDF]
Nuclear Physics, Section B, Proceedings Supplements, 2003 After a short presentation of lattice QCD and some of its current practical limitations, I review recent progress in applications to phenomenology. Emphasis is placed on heavy-quark masses and on hadronic weak matrix elements relevant for constraining the CKM unitarity triangle. The main numerical results are highlighted in boxes.

QCD phenomenology based on a chiral effective Lagrangian [PDF]
Physics Reports, 1994 We review the Nambu-Jona-Lasinio (NJL) approach to the dynamical breaking of chiral symmetry in Quantum Chromodynamics (QCD). The subjects treated in Part I include the vacuum structure of QCD, mass spectra and coupling constants of hadrons, flavor mixing in mesons, the violation of the OZI rule in baryons, and the validity of the chiral perturbation ...

Heavy quark phenomenology from lattice QCD [PDF]
Nuclear Physics, Section B, Proceedings Supplements, 2001 Recent results relevant for the B-physics phenomenology, obtained from lattice QCD simulations by the APE Collaboration, are reviewed. This includes the B0-B0bar mixing amplitude, B-> pi semileptonic decay and the relative width difference of B0_s mesons, $(ΔΓ/Γ)_{B_s}$.

The B ¯ $$ \overline{B} $$ → π form factors from QCD and their impact on |V ub | [PDF]
Journal of High Energy Physics, 2021 We revisit light-cone sum rules with pion distribution amplitudes to determine the full set of local B ¯ $$ \overline{B} $$ → π form factors. To this end, we determine all duality threshold parameters from a Bayesian fit for the first time.

Phenomenology of the companion-axion model: photon couplings
European Physical Journal C: Particles and Fields, 2022 We study the phenomenology of the ‘companion-axion model’ consisting of two coupled QCD axions. The second axion is required to rescue the Peccei–Quinn solution to the strong-CP problem from the effects of colored gravitational instantons. We investigate

The pion in the graviton soft-wall model: phenomenological applications
European Physical Journal C: Particles and Fields, 2022 The holographic graviton soft-wall model, introduced to describe the spectrum of scalar and tensor glueballs, is improved to incorporate the realization of chiral-symmetry as in QCD.

Tree-level splitting amplitudes for a gluon into four collinear partons
Journal of High Energy Physics, 2020 We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a gluon parent which splits into four collinear partons. This is part of the universal infrared behaviour of the QCD scattering amplitudes at next-to-next-to ...

Large effects from small QCD instantons: making soft bombs at hadron colliders
Journal of High Energy Physics, 2020 It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

Analytic results for Sudakov form factors in QCD
Journal of High Energy Physics, 2022 Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory.
