Instability of Higgs Vacuum via String Cloud

Issei Koga, Sachiko Kuroyanagi, Yutaka Ookouchi

We study the instability of the Higgs vacuum caused by a cloud of strings. By catalysis, the decay rate of the vacuum is highly enhanced and, when the energy density of the cloud i…

Renormalon structure in compactified spacetime

Kosuke Ishikawa, Okuto Morikawa, Kazuya Shibata +2

We point out that the location of renormalon singularities in theory on a circle-compactified spacetime $R^{d - 1} \times S^{1}$ (with a small radius $R Λ ≪ 1$ ) can differ fr…

Infrared renormalon in $S U (N)$ QCD(adj.) on $R^{3} \times S^{1}$

Masahiro Ashie, Okuto Morikawa, Hiroshi Suzuki +2

We study the infrared renormalon in the gluon condensate in the $S U (N)$ gauge theory with $n_{W}$ -flavor adjoint Weyl fermions (QCD(adj.)) on~ $R^{3} \times S^{1}$ with the $\math…

Catalytic Creation of Baby Bubble Universe with Small Positive Cosmological Constant

Issei Koga, Yutaka Ookouchi

We investigate the decay of metastable de Sitter, Minkowski and anti-de Sitter vacua catalyzed by a black hole and a cloud of strings. We apply the method to the creation of the fo…

Infrared renormalon in the supersymmetric $C P^{N - 1}$ model on $R \times S^{1}$

Kosuke Ishikawa, Okuto Morikawa, Akira Nakayama +3

In the leading order of the large- $N$ approximation, we study the renormalon ambiguity in the gluon (or, more appropriately, photon) condensate in the 2D supersymmetric $\mathbb{C}…

Fluctuation-Dissipation and Correlation-Propagation Relations in $(1 + 3)$ D Moving Detector-Quantum Field Systems

Jen-Tsung Hsiang, B. L. Hu, Shih-Yuin Lin +1

The fluctuation-dissipation relations (FDR) are powerful relations which can capture the essence of the interplay between a system and its environment. Challenging problems of this…

Derivation of a Gradient Flow from ERG

Hidenori Sonoda, Hiroshi Suzuki

We establish a concrete correspondence between a gradient flow and the renormalization group flow for a generic scalar field theory. We use the exact renormalization group formalis…

Anomaly matching in QCD thermal phase transition

Kazuya Yonekura

We study an 't Hooft anomaly of massless QCD at finite temperature. With the imaginary baryon chemical potential at the Roberge-Weiss point, there is a $Z_{2}$ symmetry whic…
