Gribov-80 Memorial Volume, 2010 I review a number of topics where conventional wisdom in hadron physics has been challenged. For example, hadrons can be produced at large transverse momentum directly within a hard higher-twist QCD subprocess, rather than from jet fragmentation.

Heavy Quark Phenomenology from Lattice QCD [PDF]
Nuclear Physics B - Proceedings Supplements, 2000 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,

QCD Phenomenology of Static Sources [PDF]
Few-Body Systems, 2004 We discuss the spectrum of open string and point particle excitations in QCD with various source representations. Some general relations are introduced and lattice results presented.

QCD Phenomenology of Charm Production at HERA [PDF]
AIP Conference Proceedings, 1997 We compare different schemes for the treatment of heavy quark production in Deep-Inelastic Scattering (DIS). For fully-integrated quantities such as $F_{2}(x,Q^{2})$, we advocate the use of the General-Massive Variable-Flavor-Number (GM-VFN) scheme; we ...

Phenomenology from lattice QCD [PDF]
Nuclear Physics 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.

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

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 ...
