Understanding the quark dynamics becomes indispensable to portray the internal structure of hadrons. This structural anatomization is carried out by making the use of light-front dynamics to understand the behavior of each constituent quark flavor of hadrons, such as spin-0 and spin-1/2 particles. Generalized parton distributions (GPDs) provide valuable three-dimensional insights of these...

Prompted by several potential tetraquark states that have been reported by the LHCb, CMS, and ATLAS Collaborations in the di-J/Ψ and J/Ψ Ψ(2S) spectra, we investigate their contribution to two-photon processes. Within a non-relativistic potential model for the all-charm tetraquark states, we calculate the two-photon decay widths of these states and test model-independent sum rule predictions....

S-matrix theory is one of the most powerful framework to study the (un)stable states that populate QCD spectrum. In particular, it is very useful to extract physical properties of the "exotics" candidates - particles that cannot be described by ordinary quark model - in a non perturbative, phenomenological way. In this talk, I will introduce the so called N/D formalism, which is a technique to...

When it comes to extracting actual testable predictions from theoretical models, perturbative QFT is one of the most successful frameworks, with Feynman diagrams being one of the key bookkeeping devices.

Understanding the small-x regime of Quantum Chromodynamics (QCD) is crucial for advancing high-energy nuclear physics. In this non-linear domain--where gluon densities become large and saturation effects emerge--traditional perturbative frameworks, such as the Parton Model, become inadequate. Instead, the Dipole Model, which is better suited for describing non-perturbative dynamics at small-x,...

Cascade hyperons, despite being discovered over half a century ago, remain considerably less studied compared to the non-strange $\Delta$ and $N$ baryons.
