Constructions of chiral polytopes of small rank [PDF]
, 2011 An abstract polytope of rank n is said to be chiral if its automorphism group has precisely two orbits on the flags, such that adjacent flags belong to distinct orbits. The present paper describes a general method for deriving new finite chiral polytopes

Isospin-breaking effects in the two-pion contribution to hadronic vacuum polarization
Journal of High Energy Physics, 2022 Isospin-breaking (IB) effects in the two-pion contribution to hadronic vacuum polarization (HVP) can be resonantly enhanced, if related to the interference of the ρ(770) and ω(782) resonances.

Non-Abelian sine-Gordon solitons
Nuclear Physics B, 2015 We point out that non-Abelian sine-Gordon solitons stably exist in the U(N) chiral Lagrangian. They also exist in a U(N) gauge theory with two N by N complex scalar fields coupled to each other.

Axial-vector transition form factors and e + e − → f 1 π + π −
Journal of High Energy Physics, 2023 We study the transition form factors (TFFs) of axial-vector mesons in the context of currently available experimental data, including new constraints from e + e − → f 1(1285)π + π − that imply stringent limits on the high-energy behavior and, for the ...

Controlled Lagrangian and Hamiltonian Systems [PDF]
, 2002 any control systems are mechanical systems. The unique feature of mechanical systems is the notion of energy, which gives much information on the stability of equilibria.

Radiative corrections to the forward-backward asymmetry in e + e − → π + π −
Journal of High Energy Physics, 2022 We present a calculation of the C-odd radiative corrections to e + e − → π + π − in a dispersive formalism, concentrating on the leading pion-pole contribution in the virtual box diagrams.

The lagrangian formulation of chiral scalars
Physics Letters B, 1987 Abstract The lagrangian proposed by Siegel describing left- or right-moving scalars in two dimensions is analysed. The existence of anomalies is pointed out and a modification of the lagrangian leading to the elimination of anomalies is proposed. The generalization for chiral scalars defined on an arbitrary Riemann surface is discussed.

European Physical Journal C: Particles and Fields, 2020 We investigate the most interesting decay processes involving axions, photons and the lightest pseudoscalar mesons, making use of a chiral effective Lagrangian model with $$L=3$$ L=3 light quark flavors, which also includes the flavor-singlet ...

a → πππ decay at next-to-leading order in chiral perturbation theory
Journal of High Energy Physics, 2022 We discuss the construction of the two-flavour axion-pion effective Lagrangian at the next-to-leading order (NLO) in chiral perturbation theory and present, as a phenomenological application, the calculation of the decay rate of a GeV-scale axion-like ...
