High-Precision Nuclear Forces From Chiral EFT: State-of-the-Art, Challenges, and Outlook

Frontiers in Physics, 2020
We review a new generation of nuclear forces derived in chiral effective field theory using the recently proposed semilocal regularization method. We outline the conceptual foundations of nuclear chiral effective field theory, discuss all steps needed to

Isospin-breaking effects in the two-pion contribution to hadronic vacuum polarization

Journal of High Energy Physics, 2022
Isospin-breaking (IB) effects in the two-pion contribution to hadronic vacuum polarization (HVP) can be resonantly enhanced, if related to the interference of the ρ(770) and ω(782) resonances.

Chiral and Gluon Condensates at Finite Temperature [PDF]

, 1994
We investigate the thermal behaviour of gluon and chiral condensates within an effective Lagrangian of pseudoscalar mesons coupled to a scalar glueball. This Lagrangian mimics the scale and chiral symmetries of QCD. (Submitted to Z. Phys.

Vector and pseudoscalar charm meson radiative decays [PDF]

, 1994
Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar $D$ mesons. We first reanalyse $D^{*} \rightarrow D \gamma$ decays within the effective Lagrangian approach using heavy quark spin ...

Axial-vector transition form factors and e + e − → f 1 π + π −

Journal of High Energy Physics, 2023
We study the transition form factors (TFFs) of axial-vector mesons in the context of currently available experimental data, including new constraints from e + e − → f 1(1285)π + π − that imply stringent limits on the high-energy behavior and, for the ...

Non-Abelian sine-Gordon solitons

Nuclear Physics B, 2015
We point out that non-Abelian sine-Gordon solitons stably exist in the U(N) chiral Lagrangian. They also exist in a U(N) gauge theory with two N by N complex scalar fields coupled to each other.

Radiative corrections to the forward-backward asymmetry in e + e − → π + π −

Journal of High Energy Physics, 2022
We present a calculation of the C-odd radiative corrections to e + e − → π + π − in a dispersive formalism, concentrating on the leading pion-pole contribution in the virtual box diagrams.

Scaling Of Chiral Lagrangians And Landau Fermi Liquid Theory For Dense Hadronic Matter [PDF]

, 1998
We discuss the Fermi-liquid properties of hadronic matter derived from a chiral Lagrangian field theory in which Brown-Rho (BR) scaling is incorporated.
