Discrete symmetries, invisible axion, and lepton number symmetry in an economic 3-3-1 model
(American Physical Soc, 2003-12-01)
We show that Peccei-Quinn and lepton number symmetries can be a natural outcome in a 3-3-1 model with right-handed neutrinos after imposing a Z(11)circle timesZ(2) symmetry. This symmetry is suitably accommodated in this ...
Minimal Composite Higgs Models at the LHC
(Springer, 2014-06)
We consider composite Higgs models where the Higgs is a pseudo-Nambu Goldstone boson arising from the spontaneous breaking of an approximate global symmetry by some underlying strong dynamics. We focus on the SO(5) → SO(4) ...
Discrete symmetries, invisible axion, and lepton number symmetry in an economic 3-3-1 model
(2003-01-01)
We show that Peccei-Quinn and lepton number symmetries can be a natural outcome in a 3-3-1 model with right-handed neutrinos after imposing a [Formula Presented] symmetry. This symmetry is suitably accommodated in this ...
Perturbative breaking of the pseudospin symmetry in the relativistic harmonic oscillator
(World Scientific Publ Co Pte Ltd, 2004-08-01)
We show that relativistic mean fields theories with scalar S, and vector V, quadratic radial potentials can generate a harmonic oscillator with exact pseudospin symmetry and positive energy bound states when S = -V. The ...

On higher spin symmetries in de Sitter QFTs
(2016-03-01)
We consider the consequences of global higher-spin symmetries in quantum field theories on a fixed de Sitter background of spacetime dimension D ≥ 3. These symmetries enhance the symmetry group associated with the isometries ...

Galilean symmetry in generalized Abelian Schrödinger?Higgs models with and without gauge field interaction
(World Scientific, 2015-11)
we consider a generalization of non-relativistic schrödinger–higgs lagrangian by introducing a nonstandard kinetic term. we show that this model is galilean invariant, we construct the conserved charges associated to the ...
Approximate symmetries and gravity
(2020-01-01)
There are strong reasons to believe that global symmetries of quantum theories cannot be exact in the presence of gravity. While this has been argued at the qualitative level, establishing a quantitative statement is more ...
