There are two mass generating mechanisms in the standard model of particle physics (SM).
One is related to the Higgs boson and fairly well understood. The other is embedded in …

The questions of how the bulk of the Universe's visible mass emerges and how it is manifest
in the existence and properties of hadrons are profound, and probe the heart of strongly …

Clear windows onto emergent hadron mass (EHM) and modulations thereof by Higgs boson
interactions are provided by observable measures of pion and kaon structure, many of which …

Analyses of the pion valence-quark distribution function (DF),, which explicitly incorporate
the behaviour of the pion wave function prescribed by quantum chromodynamics (QCD) …

We revisit the hard QCD contributions to the pion gravitational form factors, in terms of the
twist-2, 3 pion distribution amplitudes (DAs), including novel semihard contributions from the …

The pion form factors of the QCD energy-momentum tensor (EMT) are studied in the
instanton liquid model (ILM) of the QCD vacuum. In this approach, the breaking of conformal …

We present the first systematic feasibility study of accessing generalized parton distributions
of the pion at an electron-ion collider through deeply virtual Compton scattering. Relying on …

The parton distribution of the pion is obtained for the first time from the solution of a
dynamical equation in Minkowski space. The adopted equation is the homogeneous Bethe …

We study exclusive vector meson photoproduction, p V pg+ with VJ y= or ϒ, at next-to-
leading order (NLO) in collinear factorisation, in order to examine what may be learnt about …

A contact interaction is used to calculate an array of pion twist-two,-three and-four
generalised transverse light-front momentum dependent parton distribution functions …
