Quantum chromodynamics (QCDs) is the strongly interacting part of the Standard Model. It is
supposed to describe all of nuclear physics; and yet, almost 50 years after the discovery of …

The Lagrangian that defines quantum chromodynamics (QCD), the strong interaction piece
of the Standard Model, appears very simple. Nevertheless, it is responsible for an …

An electron ion collider has been proposed in China (EicC). It is anticipated that the facility
would provide polarised electrons, protons and ion beams, in collisions with large centre-of …

Finite volume methods apply directly to the conservation law form of a differential equation
system; and they commonly yield cell average approximations to the unknowns rather than …

An algebraic Ansatz for the proton's Poincaré-covariant wave function, which includes both
scalar and pseudovector diquark correlations, is used to calculate proton valence, sea, and …

The energy–momentum tensor in chiral QCD, T_ μ ν T μ ν, exhibits an anomaly,
viz.\varTheta _0:= T_ μ μ ≠ 0 Θ 0:= T μ μ≠ 0. Measured in the proton, this anomaly yields …

In pure-glue QCD, gluon–gluon scattering in the J^ PC= 0^-+ J PC= 0-+ channel is
described by a very simple equation, especially if one considers just the leading contribution …

Computable Foundations for Economics is a unified collection of essays, some of which are
published here for the first time and all of which have been updated for this book, on an …

Even though the Hamiltonian cycle problem is NP-complete, many of its problem instances
aren't. In fact, almost all the hard instances reside in one area: near the Koml\'os-Szemer\'edi …
