Bound of diffusion constants from pole-skipping points: spontaneous symmetry breaking and magnetic field [PDF]
Journal of High Energy Physics, 2021 We investigate the properties of pole-skipping of the sound channel in which the translational symmetry is broken explicitly or spontaneously. For this purpose, we analyze, in detail, not only the holographic axion model, but also the magnetically ...

Strange quark matter in the presence of explicit symmetry breaking interactions [PDF]
, 2015 It is shown that a first order transition associated with a jump in the strange quark mass appears in a generalized 3 flavour Nambu--Jona-Lasinio (NJL) treatment of quark matter.

Inhomogeneous phases in the quark-meson model with explicit chiral-symmetry breaking [PDF]
The European Physical Journal Special Topics, 2020 We investigate the existence of inhomogeneous chiral phases in the quark-meson model with explicit chiral-symmetry breaking. We find that the inhomogeneous region shrinks with increasing pion masses but survives for the physical value of mπ.

Explicit Chiral Symmetry Breaking as a Premise of the Cross-Sections' Rise [PDF]
arXiv, 2009 We argue that if QCD yields a theory of interacting hadrons then explicit chiral symmetry breaking is a necessary condition for infinitely rising cross-sections. Otherwise cross-sections go to zero at high energies.

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

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 ...

μ − τ reflection symmetry and its explicit breaking for leptogenesis in a minimal seesaw model [PDF]
Modern Physics Letters A, 2019 The minimal seesaw framework, embroiling the Dirac neutrino mass matrix [Formula: see text] and the Majorana neutrino mass matrix [Formula: see text], is quite successful to explain the current global-fit results of neutrino oscillation data.

Radiation from charged particles due to explicit symmetry breaking in a gravitational field [PDF]
, 2018 The paradox of a free falling radiating charged particle in a gravitational field is a well-known fascinating conceptual challenge that involves classical electrodynamics and general relativity (GR).

Gauged Peccei-Quinn Symmetry - A Case of Simultaneous Breaking of SUSY and PQ Symmetry [PDF]
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 symmetry.

Explicit flavor symmetry breaking and holographic compact stars [PDF]
, 2015 We study the effects of flavor symmetry breaking on holographic dense matter and compact stars in the D4/D6 model. To this end, two light flavors and one intermediate mass flavor are considered. For two light quarks, we investigate how the strong isospin
