NNLO positivity bounds on chiral perturbation theory for a general number of flavours
We present positivity bounds, derived from the principles of analyticity, unitarity and crossing symmetry, that constrain the low-energy constants of chiral perturbation theory. Bounds are produced for 2, 3 or more flavours in meson-meson scattering with

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.

On structure of effective action in four-dimensional quantum dilaton supergravity [PDF]
A general structure of effective action in new chiral superfield model associated with $N=1$, $D=4$ supergravity is investigated. This model corresponds to finite quantum field theory and does not demand the regularization and renormalization at ...

Effective chiral Lagrangians and lattice QCD [PDF]
We propose a general method to obtain accurate estimates for some of the "low-energy constants" in the one-loop effective chiral Lagrangian by means of simulating lattice QCD. In particular, the method is sensitive to those constants whose values are required to test the hypothesis of a massless up-quark.

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.

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.

Nucleon-to-Delta axial transition form factors in relativistic baryon chiral perturbation theory [PDF]
We report a theoretical study of the axial Nucleon to Delta(1232) ($N\to\Delta$) transition form factors up to one-loop order in relativistic baryon chiral perturbation theory.
