Bottom-up open EFT for non-Abelian gauge theory with dynamical color environment
Yoshihiko Abe, Kanji Nishii
We develop a bottom-up open effective field theory (EFT) for non-Abelian gauge theories within the Schwinger--Keldysh formalism. Instead of integrating out the environment complete…
Black Hole Extremality in Nonlinear Electrodynamics: A Lesson for Weak Gravity and Festina Lente Bounds
Yoshihiko Abe, Toshifumi Noumi, Kaho Yoshimura
We study black hole extremality in nonlinear electrodynamics motivated by the Weak Gravity Conjecture (WGC) and the Festina Lente (FL) bound. For illustration, we consider the Eule…
Fixed Point Structure of Gradient Flow Exact Renormalization Group for Scalar Field Theories
Yoshihiko Abe, Yu Hamada, Junichi Haruna
Gradient Flow Exact Renormalization Group (GFERG) is a framework to define the Wilson action via a gradient flow equation. We study the fixed point structure of the GFERG equation…
4D effective action from non-Abelian DBI action with magnetic flux background
Yoshihiko Abe, Tetsutaro Higaki, Tatsuo Kobayashi +2
We study a systematic derivation of four dimensional supersymmetric effective theory from ten dimensional non-Abelian Dirac-Born-Infeld action compactified on a six…
Implications of the weak gravity conjecture in anomalous quiver gauge theories
Yoshihiko Abe, Tetsutaro Higaki, Rei Takahashi
We argue a smallness of gauge couplings in abelian quiver gauge theories, taking the anomaly cancellation condition into account. In theories of our interest there exist chiral fer…
Gradient flow and the renormalization group
Yoshihiko Abe, Masafumi Fukuma
We investigate the renormalization group (RG) structure of the gradient flow. Instead of using the original bare action to generate the flow, we propose to use the effective action…
