Gauged Peccei-Quinn symmetry — A case of simultaneous breaking of SUSY and PQ symmetry
Journal of High Energy Physics, 2018 Recently, a simple prescription to embed the global Peccei-Quinn (PQ) symmetry into a gauged U(1) symmetry has been proposed. There, explicit breaking of the global PQ symmetry expected in quantum gravity are highly suppressed due to the gauged PQ ...

Abundant Symmetry-Breaking Solutions of the Nonlocal Alice–Bob Benjamin–Ono System
Complexity, 2020 The Benjamin–Ono equation is a useful model to describe the long internal gravity waves in deep stratified fluids. In this paper, the nonlocal Alice–Bob Benjamin–Ono system is induced via the parity and time-reversal symmetry reduction. By introducing an

No-go for tree-level R-symmetry breaking
European Physical Journal C: Particles and Fields, 2017 We show that in gauge mediation models with tree-level R-symmetry breaking where supersymmetry and R-symmetries are broken by different fields, the gaugino mass either vanishes at one loop or finds a contribution from loop-level R-symmetry breaking. Thus

Effective restoration of the U_A(1) symmetry with temperature and density [PDF]
, 2004 We investigate the full U(3)$\otimes$U(3) chiral symmetry restoration, at finite temperature and density, on the basis of a quark model which incorporates the most relevant properties of QCD in this context: explicit and spontaneous breaking of chiral ...

Noether identities in gravity theories with nondynamical backgrounds and explicit spacetime symmetry breaking [PDF]
, 2016 Gravitational effective field theories with nondynamical backgrounds explicitly break diffeomorphism and local Lorentz invariance. At the same time, to maintain observer independence the action describing these theories is required to be mathematically ...

$$ \mu -\tau $$ μ-τ reflection symmetry embedded in minimal seesaw
European Physical Journal C: Particles and Fields, 2018 We embed $$\mu -\tau $$ μ-τ reflection symmetry into the minimal seesaw formalism, where two right-handed neutrinos are added to the Standard Model of particle physics. Assuming that both the left- and right-handed neutrino fields transform under $$\mu -\

The effective action of superrotation modes
Journal of High Energy Physics, 2021 Starting from an analysis of four-dimensional asymptotically flat gravity in first order formulation, we show that superrotation reparametrization modes are governed by an Alekseev-Shatashvili action on the celestial sphere.

Supersymmetry Breaking, R-Symmetry Breaking and Metastable Vacua
, 2007 Models of spontaneous supersymmetry breaking generically have an R-symmetry, which is problematic for obtaining gaugino masses and avoiding light R-axions.

“Explicit versus dynamical” breaking of chiral symmetry
Physics Letters B, 1989 Abstract We study the explicit and dynamical breaking of chiral symmetry in the (2+1)-dimensional four-Fermi model. The model is renormalizable in the 1 N f expansion. We calculate the masses of the fermions and pseudo-Goldstone bosons in terms of the explicit breaking parameters.

Dark matter from a complex scalar singlet: the role of dark CP and other discrete symmetries
Journal of High Energy Physics, 2021 We study the case of a pseudo-scalar dark matter candidate which emerges from a complex scalar singlet, charged under a global U(1) symmetry, which is broken both explicitly and spontaneously.
