Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Extracting the chiral anomaly from e + e − → 3π

Journal of High Energy Physics
The strength of the interaction of three pions and a photon, F 3π is predicted by the axial anomaly in terms of the pion decay constant, a relation that is frequently used to constrain low-energy radiative processes involving pions, but only tested ...

Chiralspin Symmetry and Its Implications for QCD

Universe, 2019
In a local gauge-invariant theory with massless Dirac fermions, a symmetry of the Lorentz-invariant fermion charge is larger than a symmetry of the Lagrangian as a whole.

On chiral excitations with exotic quantum numbers

Physics Letters B, 2019
We consider the flavour sextet of charmed meson resonances with JP=1+ quantum numbers that is predicted by the leading order chiral Lagrangian with up, down and strange quarks.

Exotic meson decays in the environment with chiral imbalance

EPJ Web of Conferences, 2017
An emergence of Local Parity Breaking (LPB) in central heavy-ion collisions (HIC) at high energies is discussed. LPB in the fireball can be produced by a difference between the number densities of right- and left-handed chiral fermions (Chiral Imbalance)

Dynamical vector resonances from the EChL in VBS at the LHC: the WW case

Journal of High Energy Physics, 2019
In this work we study the phenomenology of the process pp → W + W − jj at the LHC, in the scenario of the resonant vector boson scattering subprocess W + W − → W + W − which we describe within the effective field theory framework of the Electroweak ...

Chiral lagrangians and WW scattering

Nuclear Physics B, 1991
Recently, it has been proposed that the scattering of strongly interacting longitudinal gauge bosons can be studied using chiral perturbation theory. By fitting the energy dependence of the scattering amplitudes in the energy region 0.5 TeV < √s < 1.2 TeV one is sensitive to the nature of electroweak symmetry breaking.

Infrared enhancement of supersymmetry in four dimensions

Journal of High Energy Physics, 2018
We study a recently-found class of RG flows in four dimensions exhibiting enhancement of supersymmetry in the infrared, which provides a lagrangian description of several strongly-coupled N=2 SCFTs.
