The cosmological constant from the ghost. A toy model
Federico R. Urban, Ariel R. Zhitnitsky
We suggest that the solution to the cosmological vacuum energy puzzle is linked to the infrared sector of the effective theory of gravity interacting with standard model fields. We…
The cosmological constant as a manifestation of the conformal anomaly?
Evan C. Thomas, Federico R. Urban, Ariel R. Zhitnitsky
We propose that the solution to the cosmological vacuum energy puzzle may come from the infrared sector of the effective theory of gravity, where the impact of the trace anomaly is…
On Classification of QCD defects via holography
Alexander Gorsky, Valentin Zakharov, Ariel Zhitnitsky
We discuss classification of defects of various codimensions within a holographic model of pure Yang-Mills theories or gauge theories with fundamental matter. We focus on their rol…
