Complete one-loop renormalization of the Higgs-electroweak chiral Lagrangian [PDF]

, 2018
Employing background-field method and super-heat-kernel expansion, we compute the complete one-loop renormalization of the electroweak chiral Lagrangian with a light Higgs boson.

Implications of a new effective chiral meson Lagrangian [PDF]

, 2002
Based on a recently derived effective chiral meson Lagrangian from the extended SU(2)[circle times operator]SU(2) Nambu-Jona-Lasinio (ENJL) model, in the linear realization of chiral symmetry, we extract to leading order in the 1/Nc expansion all ...

Strong CP-violation in an effective chiral Lagrangian approach [PDF]

, 1991
Possible long-distance effects like eta --> pi-pi and the electric dipole moment of the neutron (nEDM), which may originate in the strong CP-non-conserving sector of QCD, are re-examined in the light of an effective chiral lagrangian approach.

Chiralspin Symmetry and Its Implications for QCD

Universe, 2019
In a local gauge-invariant theory with massless Dirac fermions, a symmetry of the Lorentz-invariant fermion charge is larger than a symmetry of the Lagrangian as a whole.

Multi-skyrmion solutions of a sixth order skyrme model [PDF]

, 2001
In this Thesis, we study some of the classical properties of an extension of the Skyrme model defined by adding a sixth order derivative term to the Lagrangian.

A simple chiral Lagrangian approach toK→πππ decays andε′+0− [PDF]

, 1989
We analyse the K~nrcn decays in the framework of a chiral Lagrangian supplemented by the 1IN expansion (N being the number of colors). The measured KL--*n+Tz~ - Dalitz plot is very well reproduced.

On chiral excitations with exotic quantum numbers

Physics Letters B, 2019
We consider the flavour sextet of charmed meson resonances with JP=1+ quantum numbers that is predicted by the leading order chiral Lagrangian with up, down and strange quarks.

Exotic meson decays in the environment with chiral imbalance

EPJ Web of Conferences, 2017
An emergence of Local Parity Breaking (LPB) in central heavy-ion collisions (HIC) at high energies is discussed. LPB in the fireball can be produced by a difference between the number densities of right- and left-handed chiral fermions (Chiral Imbalance)

Dynamical vector resonances from the EChL in VBS at the LHC: the WW case

Journal of High Energy Physics, 2019
In this work we study the phenomenology of the process pp → W + W − jj at the LHC, in the scenario of the resonant vector boson scattering subprocess W + W − → W + W − which we describe within the effective field theory framework of the Electroweak ...

Resonance chiral Lagrangian currents and experimental data for τ−→π−π−π+ντ [PDF]

, 2013
In this paper we document the modifications introduced to the previous version of the Resonance Chiral Lagrangian current ({\it Phys.Rev.} {\bf D86} (2012) 113008) of the $\tau^\pm \to \pi^\pm \pi^\pm \pi^\mp \nu_\tau$ decay which enable the one ...
