Generalisations of the MHV lagrangian theory to D-dimensions and to super-space [PDF]
, 2010 It has been known that the CSW rules correctly reproduce all tree-level scattering amplitudes for perturbative non-abelian gauge theory but fail to explain some of the loop order results.

Nucleon magnetic form factors with non-local chiral effective Lagrangian [PDF]
, 2014 Chiral perturbation theory is a useful method to investigate the hadron properties. We apply the non-local chiral effective Lagrangian to study the nucleon magnetic form factors.

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

The Lagrangian method for chiral symmetry [PDF]
, 1969 We describe the non linear realizations of chiral symmetry group and study some of its implications in elementary particle phycics. In Chapter 1, the basic concepts of non linear realization techniques are introduced the way of reviewing the special case

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Meson-Baryon Effective Chiral Lagrangian at $O(q^3)$ Revisited [PDF]
, 2007 After our work [1] was published, Frink and Meissner [2] pointed out that the O(q^3) three-flavour meson-baryon chiral Lagrangian presented there was not minimal. Here, we critically review their paper and revise ours.

Matching from quark to hadronic operators: external source vs spurion methods
Journal of High Energy PhysicsVarious weak processes at the hadronic scale have been utilized to search for new physics at high energy scale, which can be described by the QCD chiral Lagrangian matched from the low-energy effective theory (LEFT). Utilizing the chiral symmetry SU(2) L

Hard thermal loops and chiral Lagrangians [PDF]
Physical Review D, 1998 Chiral symmetry is used as the guiding principle to derive hard thermal loop effects in chiral perturbation theory. This is done by using a chiral invariant background field method for the non-linear sigma model and the Wess-Zumino-Witten lagrangian, with and without external vector and axial vector sources.
