The degrees of freedom observed in hadronic collisions at high energies can be  strongly entangled with the rest  degrees of freedom in the initial light cone hadronic wavefunction. The coherence of the incoming hadron is destroyed by the interaction with the target; this may lead to the transformation of   the entropy associated with the entanglement into the thermodynamics entropy of produced ...

Among the basic questions posed by Nature, the following three are basic to hadron physics: How does the ≈ 1 GeV mass-scale that characterizes atomic nuclei appear; Why does it have the observed value; and, enigmatically, why are the composite Nambu-Goldstone bosons in QCD abnormally light in comparison? This presentation will describe analyses of the mass budget of the pion and proton in QCD; ... More

We present recent collaborative efforts for solving the bound state Bethe-Salpeter equation in the Minkowski space with the use of the Nakanishi integral representation and also by explicit rotation of the Euclidean energy axis towards the Minkowski axis. We are envisaging future applications to hadrons and in particular to model the pion. In order to do so, we also have to use similar technique ... More

We present a statistical description of the hadron structures in terms of the parton gas on the light front. Specifically, the microcanonical molecular dynamics ensemble is generalized to preserve the light front 3-momentum in order to model the phase space distribution of partons confined inside a hardon. With only the light front kinetic energy, the joint longitudinal momentum fraction distribut ... More

We will present our lattice computation of the valence Parton Distribution Function of 300 MeV pion. For this work, we use perturbative matching of the Euclidean RI-MOM renormalized quasi Parton Distribution Function that we compute on HISQ ensembles with 0.06 and 0.04 fm lattice spacings. In addition, we will discuss the validity of leading order perturbative matching and other systematic effec ... More

An understanding of the partonic structure of hadrons is an essential ingredient in making precise predictions and measurements of hadronic cross-sections and various Standard, and Beyond Standard, Model parameters. Direct first-principles calculations of parton distribution functions (PDFs) via lattice QCD were historically limited to the lowest few moments, principally due to the time-dependence ... More

Owing to the growing availability of computational resources as well as steady theoretical advances in lattice gauge theory and perturbative QCD analyses, the dual technologies of Lattice QCD and QCD Global Analyses have proceeded apace in recent years. In this context, it is increasingly suggested that the output of Lattice QCD calculations could serve as important input to Global Analyses of PD ... More
