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

Constraints on chiral operators in N=2 SCFTs [PDF]
, 2014 : We study certain higher-spin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality (“type A”

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 ...

Self-interacting chiral p-forms in higher dimensions
Physics Letters B, 2019 There exists no natural variational principle for the dynamics of abelian p-form potentials with self-dual field strengths, also called chiral p-forms. Relying on the PST method, we establish the general consistency condition for a Lagrangian to describe

Parity-violating πNN coupling constant from the flavor-conserving effective weak chiral Lagrangian
Physics Letters B, 2017 We investigate the parity-violating pion–nucleon–nucleon coupling constant hπNN1, based on the chiral quark-soliton model. We employ an effective weak Hamiltonian that takes into account the next-to-leading order corrections from QCD to the weak ...

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 three-pion contribution to hadronic vacuum polarization
Journal of High Energy Physics, 2023 Isospin-breaking (IB) effects are required for an evaluation of hadronic vacuum polarization at subpercent precision. While the dominant contributions arise from the e + e − → π + π − channel, also IB in the subleading channels can become relevant for a ...
