Quantum-chromodynamic evolution of the baryon system.
We present a general method for solving the QCD evolution equations which govern relativistic multi-quark wavefunctions. In the case of three-quark systems, we generate a light-cone basis of completely antisymmetric wavefunctions. This provides a general covariant classification of baryonic states. We then calculate the spin-orbit mixing generated by the QCD evolution kernel in the basis of com...
متن کاملQuantum-chromodynamic evolution of six-quark states.
The evolution of six-quark color-singlet state distribution amplitudes is formulated as an application of perturbative quantum chromodynamics to nuclear wave functions. We derive and solve a set of coupled evolution equations for the deuteron S-wave amplitude. The solution of the evolution equations leads to a general matrix representation of anomalous dimensions which can be used to analyze th...
متن کاملQuantum Chromodynamic Evolution of Multiquark Systems
We present a new technique which extends the quantum chromodynamic evolution formalism in order to predict the short distance behavior of multiquark wavefunctions. In particular, predictions are given for the deuteron reduced form factor in the high momentum transfer region, and rigorous constraints on the short distance effective force between two baryons are predicted. These new techniques ca...
متن کاملQUANTUM - CHROMODYNAMIC PREDICTIONS FOR DIRECT PHOTONS IN e + e - COLLISIONS
We analyze the direct photon production in e+ecollisions in quantum chromodynamics using the cut vertex formalism and renormalization group method. The two-loop anomalous dimensions of time-like cut vertices are calculated from the two-loop parton decay probability functions. The moments of the transverse structure function $ are calculated up to the next-to-leading order. The nonleading correc...
متن کاملNonperturbative gadget for topological quantum codes.
Many-body entangled systems, in particular topologically ordered spin systems proposed as resources for quantum information processing tasks, often involve highly nonlocal interaction terms. While one may approximate such systems through two-body interactions perturbatively, these approaches have a number of drawbacks in practice. In this Letter, we propose a scheme to simulate many-body spin H...
