On the amplitudes for the CP-conserving K ±(K S ) → π ±(π 0)ℓ + ℓ − rare decay modes
The amplitudes for the rare decay modes K ± → π ± ℓ + ℓ − and K S → π 0 ℓ +ℓ− are studied with the aim of obtaining predictions for them, such as to enable the possibility to search for violations of lepton-flavour universality in the kaon sector.

The lagrangian formulation of chiral scalars
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.

On QCD predictions for the chiral Lagrangian coefficients [PDF]
Based on a previous study of deriving the chiral Lagrangian (CL) from QCD, we illustrate the main feature of QCD predictions for the CL coefficients (CLC) in certain approximations. We first show that, in the large-N(c) limit, the anomaly part contributions to the CLC are exactly cancelled by certain terms in the normal part contributions (NPC), so ...

T-duality transformation of gauged linear sigma model with F-term
We develop the duality transformation rules in two-dimensional theories in the superfield formalism. Even if the chiral superfield which we dualize involves an F-term, we can dualize it by virtue of the property of chiral superfields.

Anomalous effective lagrangians and vector resonance models [PDF]
Chiral lagrangians including vector resonances have been shown to saturate the finite part of some of the counterterms needed to regularize ordinary one-loop effective lagrangians of pseudoscalar interactions with external currents.

On the off-shell superfield Lagrangian formulation of 4D, N=1 supersymmetric infinite spin theory
We develop a complete off-shell Lagrangian description of the free 4D,N=1 supersymmetric theory of infinite spin. Bosonic and fermionic fields are formulated in terms of spin-tensor fields with dotted and undotted indices.

Holography and chiral Lagrangian [PDF]
In a wide class of holographic models described by the Yang-Mills and Chern-Simons terms, we derive all the ${\cal O}(p^6)$ Chiral Perturbation Theory low-energy constants. Various model-independent relations exist among the constants up to this order, generalizing the previously found relations at $p^4$ order. Some of them can be extended to relations

Guiding and Manipulating Light Fields in Microstructured Liquid Crystals
This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Chiral Lagrangians and Nambu-Jona-Lasinio like models [PDF]
We discuss the low-energy analysis of models involving quarks and four-fermion couplings. The relation with QCD and with other models of mesons and meson plus quarks at low energies is discussed.
