A variational approach to hadron structure in lattice QCD
In order to understand how hadrons acquire their physical properties from their constituents, we must resort to the underlying theory of the strong interaction, Quantum Chromodynamics (QCD). However, the non-perturbative nature of this theory in the relevant energy scales renders the standard …

Exploring Hadron Structure Through Monte-Carlo Fits and Model Calculations
… effort to understand the proton's internal structure. There still remain many mysteries about the proton and the theory that describes the interactions within: Quantum Chromodynamics (QCD). The distributions of quarks and gluons are encoded in objects known as parton correlation functions. …

Studies in hadron structure using lattice QCD with quark masses that almost reach the physical point
Lattice QCD allows us to study the structure of hadrons from first-principles calculations of quantum chromodynamics. We present calculations that shed light on the behavior of quarks inside hadrons in both qualitative and quantitative ways. The first is a study of diquarks. We bind two quarks in a …

Studies of Ξ+c production in pPb collisions
… can provide important information on the hadronisation of charm hadrons, as well as on the hadron structure. Since the Ξc+ contains s quark, the enhancement can be an indication of Quark Gluon Plasma formation.

Exclusive photoproduction of charged pions in hydrogen and deuterium from 1 to 6 GeV
… in the description of exclusive processes and hadron structure, from the nucleon-meson degrees of freedom in meson-exchange models at low energy to the quark-gluon degrees of freedom in pQCD at high energy, is essential for us to understand the strong interaction. The differential cross section …

A Study of the Λ(1405) in Lattice QCD
… been significant effort expended to describe the structure of the Λ(1405), however there has been no convincing resolution. It is very difficult to reconcile this low mass with the quark model interpretation for this state, and lattice QCD studies have consistently failed to reproduce it. In this …
