Description

The quark-matter phase of neutron stars is thought to be governed by short-range interactions among quark and gluons within Quantum Chromodynamics (QCD). Pressure, energy, as well as other mechanical properties of the nucleon are encoded in the QCD Energy-Momentum Tensor. The matrix elements of this tensor are connected to the Mellin moments of the generalized parton distributions which can be measured in deeply virtual exclusive scattering experiments. We establish a connection between observables from high-energy experiments and from the analysis of gravitational-wave events.
