We present the first proof of concept extraction using neural networks (NNs) of the unpolarized transverse-momentum distributions (TMDs) at next-to-next-to-next-to-leading logarithmic (N$^3$LL) accuracy. By offering a more flexible and adaptable approach, NNs overcome some of the limitations of traditional functional forms, providing a better description of data.

Deeply Virtual Compton Scattering (DVCS) is a powerful tool to investigate the internal structure of hadrons in terms of Generalized Parton Distributions (GPDs). The Sullivan process, involving the exchange of a virtual pion from the proton’s meson cloud, offers a unique opportunity to access the three-dimensional structure of the pion at high energies. Since the pion plays a central role in...

Inclusive processes pose a long-standing challenge for lattice QCD due to their inherently multi-hadron nature and the need to access fully summed final states. Here, we demonstrate how first-principles methods can now overcome these obstacles through spectral reconstruction techniques. We present a first-principles lattice QCD study of the inclusive semileptonic decays of the $D_s$ meson,...

The masses of visible matter arise from both the Higgs mechanism and strong interactions, yet how six Higgs-generated quark masses and flavor-neutral gluons jointly determine the hadron spectrum remains unclear. Using state-of-the-art lattice QCD with controlled continuum and infinite-volume extrapolations, we predict ground-state spin-1/2 and spin-3/2 baryon masses containing light, strange,...

The fusion barrier studies at energies around the Coulomb barrier have been a topic of great interest. At these energies, the coupling between relative motion and internal degrees of freedom of colliding heavy ions is strongly affected, which results in a number of distributed barriers instead of a single barrier (Bfus) [1-6]. A barrier distribution (BD) can be extracted experimentally from...

The P2 experiment aims for a high precision measurement of the weak mixing angle, a fundamental parameter of the Standard Model. The weak mixing angle will be extracted from the parity-violating asymmetry in elastic electron-proton scattering at low momentum transfer, with an expected raw asymmetry of $A_\text{raw} = 0.2403\times 10^{-7}$. The central component of the detector system is an...

We assess the potential of using deuteron photodisintegration around the neutron quasi-free peak as a dual-purpose experiment to simultaneously constrain neutron polarizabilities and probe physics beyond the Standard Model.

The parton distribution functions (PDFs) are crucial to the understanding of the internal structure of hadrons, and their precise determination is necessary for searches of BSM physics in collider experiments.

Two-photon exchange (TPE) is one of the leading explanations for discrepancies in measurements of the proton electromagnetic form factors.
