On Different Formulations of Chiral Bosons [PDF]

open access: yes, 1999
It is shown, that recently constructed PST Lagrangians for chiral supergravities follow directly from earlier Kavalov-Mkrtchyan Lagrangians by an Ansatz for the ' tensor by expressing this in terms of the PST scalar.

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

open access: yesFortschritte der Physik, Volume 73, Issue 9-10, October 2025.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Strange form factors and Chiral Perturbation Theory

open access: yes, 2005
We review the contributions of Chiral Perturbation Theory to the theoretical understanding or not-quite-yet-understanding of the nucleon matrix elements of the strange vector current.PACS: 12.39.Fe Chiral Lagrangians – 14.20.Dh Protons and ...

Refining the scalar and tensor contributions in τ → πππν τ decays

open access: yesJournal of High Energy Physics, 2017
In this article we analyze the contribution from intermediate spin-0 and spin-2 resonances to the τ → νπππ decay by means of a chiral invariant Lagrangian incorporating these mesons.

Holomorphic field theories and higher algebra

open access: yesBulletin 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 ...

Chiral Lagrangians and Nambu-Jona-Lasinio like models

open access: yes, 1995
We discuss the low-energy analysis of models involving quarks and four-fermion couplings. The relation with QCD and with other models of mesons and meson plus quarks at low energies is discussed.

Hidden-charm and hidden-bottom molecular pentaquarks in chiral effective field theory

open access: yesJournal of High Energy Physics, 2019
The newly observed P c (4312), P c (4440) and P c (4457) at the LHCb experiment are very close to the Σ c D ¯ $$ {\varSigma}_c\overline{D} $$ and Σ c D ¯ ∗ $$ {\varSigma}_c{\overline{D}}^{\ast } $$ thresholds.

The dual properties of chiral and isospin asymmetric dense quark matter formed of two-color quarks

open access: yesJournal of High Energy Physics, 2020
In this paper the phase structure of dense baryon matter composed of u and d quarks with two colors has been investigated in the presence of baryon μ B , isospin μ I and chiral isospin μ I5 chemical potentials in the framework of Nambu-Jona-Lasinio model

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

open access: yesAstronomische 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.

From Nano Robotic Manipulation to Nano Manipulation Robot

open access: yesSmartBot, Volume 1, Issue 3, September 2025.
This review addresses a critical research gap by summarizing advancements in nano robotic manipulation, tracing its evolution from passive observation to autonomous nanomanipulation robots. It explores the interplay of observation, construction, and operation, unveiling fundamental principles of atomic‐scale control. The review establishes a systematic
