Dark QCD perspective inspired by strong CP problem at QCD scale

Journal of High Energy Physics
We discuss a QCD-scale composite axion model arising from dark QCD coupled to QCD. The presently proposed scenario not only solves the strong CP problem, but also is compatible with the preheating setup for the QCD baryogenesis.

Abelian Decomposition and Monopole Condensation in QCD

EPJ Web of Conferences, 2018
We demonstrate the monopole condensation in QCD using the Abelian decomposition. The Abelian decomposition decomposes the gluons to the color neutral binding gluons (the neurons and the monopoles) and the colored valence gluons (the chromons), and shows ...

QCD fishnets revisited

Physical Review D, 2000
We look back at early efforts to approximate the large N_c Feynman diagrams of QCD as very large fishnet diagrams. We consider more carefully the uniqueness of rules for discretizing P^+ and ix^+ which fix the fishnet model in the strong 't Hooft coupling limit, and we offer some refinements that allow more of the crucial QCD interactions to be ...

Constraints on the variation of the QCD interaction scale ΛQCD

Journal of High Energy Physics
Laboratory and astrophysical tests of “constant variation” have so far concentrated on the dimensionless fine-structure constant α and on the electron or quark mass ratios X e,q = m e,q /ΛQCD, treating the QCD scale ΛQCD as unchangeable.

Two-baryon systems from HAL QCD method and the mirage in the temporal correlation of the direct method

EPJ Web of Conferences, 2018
Both direct and HAL QCD methods are currently used to study the hadron interactions in lattice QCD. In the direct method, the eigen-energy of two-particle is measured from the temporal correlation. Due to the contamination of excited states, however, the

QCD and Jets

Acta Physica Polonica B, 2013
We address aspects of jet physics at the Large Hadron Collider, focusing on features of recent jet measurements which challenge the theory. We discuss examples illustrating the role of QCD parton showers, nonperturbative corrections, soft multi-gluon emission.

The QCD spectrum

Nuclear Physics B - Proceedings Supplements, 1995
Recent results in light hadron spectroscopy are reviewed. Attention is given to the requirements of precision determinations in lattice gauge theory. Different methods for extracting the running coupling constant $ _S$ are compared. Some recent results in determining the nature of the interaction between static quarks are also discussed.

Chiral separation effect from holographic QCD

Journal of High Energy Physics
We analyze the chiral separation effect (CSE) in QCD by using the gauge/gravity duality. In QCD, this effect arises from a combination of chiral anomalies and the axial U(1) anomaly.
