Static and dynamic properties of the pion from continuum modelling of strong QCD [PDF]
, 2010 We present nonperturbative numerical solutions for the quark propagator Schwinger-Dyson equation (SDE) and pseudoscalar meson Bethe-Salpeter equation (BSE) at and beyond the rainbow-ladder truncation level of this system of equations.

A light NMSSM pseudoscalar Higgs boson at the LHC redux [PDF]
, 2015 The Next-to-Minimal Supersymmetric Standard Model (NMSSM) contains a singlet-like pseudoscalar Higgs boson in addition to the doublet-like pseudoscalar of the Minimal Supersymmetric Standard Model.

Decay of charmonium states into a scalar and a pseudoscalar glueball
EPJ Web of Conferences, 2016 In the framework of a chiral symmetric model, we expand a U(4)R × U(4)L symmetric linear sigma model with (axial-)vector mesons by including a dilaton field, a scalar glueball, and the pseudoscalar glueball.

Exact formula of the spectrum of the pseudoscalar octet
Physics Letters B, 2015 Non-perturbative proof is presented of a generalized version of Goldstone theorem, where the Lagrangian conserves an approximate SU(3) chiral symmetry, that both quark masses and electromagnetism make contributions to the masses of spinless particles of ...

Geometric Stabilization of Biomolecular Chirality in Open Systems
Chirality, Volume 38, Issue 6, June 2026.Entropic topology favors orientation‐preserving deformations in molecular configuration space, leading to a spontaneous statistical bias toward right‐handed α$$ \alpha $$‐helices. The figure illustrates how configurations with positive determinant (dextral) occupy a larger accessible volume of microstates, providing a purely geometric‐entropic ...

Thermal quarkonium physics in the pseudoscalar channel [PDF]
, 2017 The pseudoscalar correlator is an ideal lattice probe for thermal modifications to quarkonium spectra, given that it is not compromised by a contribution from a large transport peak.

New Journal of PhysicsA search for a pair of low-mass pseudoscalars $a$ that promptly decay into $\tau$ -leptons is presented using 140 fb $ ^{-1}$ of proton–proton collision data at $13$ TeV centre-of-mass energy recorded with the ATLAS detector at the Large Hadron Collider.

Radiative Decay Widths of Ground and Excited States of Vector Charmonium and Bottomonium
Advances in High Energy Physics, 2017 We study the radiative decay widths of vector quarkonia for the process of J/ψ(nS)→ηc(nS)γ and Υ(nS)→ηb(nS)γ (for principal quantum numbers n=1,2,3) in the framework of Bethe-Salpeter equation under the covariant instantaneous ansatz using a 4×4 form of ...

Photonics of Topological Magnetic Textures
Advanced Optical Materials, Volume 14, Issue 13, 3 April 2026.Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...
