A Supersymmetric Effective Chiral Lagrangian [PDF]
Physics Letters B, 1994 We construct in a manifestly supersymmetric form the leading and subleading terms in momentum for an effective supersymmetric chiral Lagrangian in terms of complex pions and their superpartners.

Holography and chiral Lagrangian [PDF]
AIP Conference Proceedings, 2012 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.

Chiral Lagrangian with confinement from the QCD Lagrangian [PDF]
Physical Review D, 2002 An effective Lagrangian for the light quark in the field of a static source is derived systematically using the exact field correlator expansion. The lowest Gaussian term is bosonized using nonlocal colorless bosonic fields and a general structure of ...

Constrained Electroweak Chiral Lagrangian [PDF]
The Origin of Mass and Strong Coupling Gauge Theories, 2007 We update the uncertainty analysis on $S$ parameter of the electroweak chiral Lagrangian (EWCL) by including the LEP-II W pair production data. We find that experimental data still allow a positive $S^{EXP}(1\textrm{TeV})$.Comment: 7 pages, 2 figures ...

The order p 8 mesonic chiral Lagrangian [PDF]
Journal of High Energy Physics, 2019 We derive the chiral Lagrangian at next-to-next-to-next-to-leading order (NNNLO) for a general number N f of light quark flavours as well as for N f = 2, 3. We enumerate the contact terms separately.

On the minimality of the order p6 chiral Lagrangian [PDF]
Physics Letters B, 2015 A method to find relations between the operators in the mesonic Lagrangian of Chiral Perturbation Theory at order p6 is presented. The procedure can be used to establish if the basis of operators in the Lagrangian is minimal.

The Electroweak Chiral Lagrangian and New Precision Measurements [PDF]
Physical Review D, 1993 A revised and complete list of the electroweak chiral lagrangian operators up to dimension-four is provided. The connection of these operators to the $S$, $T$ and $U$ parameters and the parameters describing the triple gauge boson vertices $WW\gamma$ and

On the off-shell superfield Lagrangian formulation of 4D, N=1 supersymmetric infinite spin theory
Physics Letters B, 2022 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.

2, 12, 117, 1959, 45171, 1170086, …: a Hilbert series for the QCD chiral Lagrangian
Journal of High Energy Physics, 2021 We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation is

Species Doubling and Chiral Lagrangians [PDF]
Physical Review Letters, 1996 Coupling gauge fields to the chiral currents from an effective Lagrangian for pseudoscalar mesons naturally gives rise to a species doubling phenomenon similar to that seen with fermionic fields in lattice gauge theory.
