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. A soft supersymmetry breaking term is included and below the supersymmetry breaking scale the Lagrangian reduces to the usual bosonic chiral Lagrangian in ...

Chiral Lagrangians and the QCD string [PDF]
Physics Letters B, 1999 We propose a method to derive the low-energy efective action of QCD assuming that the long-distance properties of strong interactions can be described by a string theory. We bypass the usual problems related to the existence of the tachyon and absence of the adequate Adler zero by using a sigma model approach where excitations above the correct ...

Chiral Lagrangian for excited pions [PDF]
Physical Review D, 1997 We construct a chiral Lagrangian containing besides the usual pion field (pi) also its first radial excitation (pi'). The Lagrangian is derived by bosonization of a Nambu--Jona-Lasinio quark model with separable non-local interactions, with form factors corresponding to 3-dimensional ground and excited state wave functions.

Lattice Quantum ChromoDynamics with approximately chiral fermions [PDF]
, 2008 In this work we present Lattice QCD results obtained by approximately chiral fermions. We use the CI fermions in the quenched approximation to investigate the excited baryon spectrum and to search for the Theta^+ pentaquark on the lattice. Furthermore we

A systematic approach to the SILH Lagrangian
Nuclear Physics B, 2015 We consider the electroweak chiral Lagrangian, including a light scalar boson, in the limit of small ξ=v2/f2. Here v is the electroweak scale and f is the corresponding scale of the new strong dynamics.

Unitarized one-loop graviton-graviton scattering [PDF]
EPJ Web of Conferences, 2022 In this work we interpret the Einstein-Hilbert (EH) Lagrangian of gravitation as the first term of a low-energy effective theory similar to those considered in the chiral Lagrangian approach to low-energy hadron physics or the electroweak chiral ...
