Chiral Lagrangian for strange hadronic matter [PDF]

open access: yes, 2006
A generalized Lagrangian for the description of hadronic matter based on the linear SU(3)L × SU(3)R -model is proposed. Besides the baryon octet, the spin-0 and spin-1 nonets, a gluon condensate associated with broken scale invariance is incorporated ...

Precision measurement constraints on the 4-Site model & the effect of interference in searches for new physics [PDF]

open access: yes, 2013
This work is divided in two parts.The first part presents a careful computation of Electroweak Precision Tests constraints on the 4-Site model, and the resulting limits on fermion couplings.

Chiral oscillations in finite time quantum field theory

open access: yesEuropean Physical Journal C: Particles and Fields
We demonstrate how chiral oscillations of a massive Dirac field can be described within quantum field theory using a finite-time interaction picture approach, where the mass term in the Lagrangian is treated as a perturbative coupling between massless ...

T-duality invariant approaches to string theory [PDF]

open access: yes, 2010
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.

Axion production in the η → ππa decay within SU(3) chiral perturbation theory

open access: yesJournal of High Energy Physics
We study the axion and axion-like particle production from the η → ππa decay within the SU(3) chiral perturbation theory up to the one-loop level. The conventional SU(3) chiral low energy constants are found to be able to reabsorb all the divergences ...

The electroweak chiral Lagrangian reanalyzed [PDF]

open access: yes, 1999
In this paper we reanalyze the electroweak chiral Lagrangian with particular focus on two issues related to gauge invariance. Our analysis is based on a manifestly gauge-invariant approach that we introduced recently.

Learning holographic QCD with unflavored meson spectra

open access: yesJournal of High Energy Physics
We develop a data-driven neural network framework to reconstruct the five-dimensional background geometry, the dilaton potential, and the chiral-symmetry-breaking scalar potential of holographic QCD from hadron mass spectra. Framed as an inverse problem,
