Mixed scalar-pseudoscalar Higgs boson production through next-to-next-to-leading order at the LHC
Journal of High Energy Physics, 2020 We study the production of a mixed scalar-pseudoscalar Higgs boson in gluon fusion at the LHC, through next-to-next-to-leading order (NNLO) in QCD. We obtain fully differential results, including the decay of the Higgs boson to two charged lepton pairs ...

Fermionic bound states and pseudoscalar exchange [PDF]
Journal of Physics G: Nuclear and Particle Physics, 1999 We discuss the possibility that fermions bind due to Higgs or pseudoscalar exchange. It is reasonable to believe on qualitative grounds that this can occur for fermions with a mass larger than 800-900 GeV. An exchange of a pseudoscalar boson leads in the non-relativistic limit to an unacceptable potential which behaves like 1/r^3 at the origin. We show

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

Excited scalar and pseudoscalar mesons in the extended linear sigma model
European Physical Journal C: Particles and Fields, 2017 We present an in-depth study of masses and decays of excited scalar and pseudoscalar $${\bar{q}}q$$ q ¯ q states in the Extended Linear Sigma Model (eLSM). The model also contains ground-state scalar, pseudoscalar, vector and axial-vector mesons.

Unsuitable use of spin and pseudospin symmetries with a pseudoscalar Cornell potential
, 2014 The concepts of spin and pseudospin symmetries has been used as mere rhetorics to decorate the pseudoscalar potential [Chin. Phys. B 22 090301 (2013)].

Pseudoscalar Field as a Possible Candidate for Phantom Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We demonstrate the existence of a single pseudoscalar (PS) field in the mathematically backed and parity‐preserving modifications of the standard Stückelberg formalism (SSF) in the context of the Lagrangian formulation of the (i) two (1 + 1)‐dimensional (2D) massive Abelian 1‐form gauge theory, (ii) three (2 + 1)‐dimensional (3D) massive Abelian 2‐form

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We obtain the off‐shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti‐BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three (2 + 1)‐dimensional (3D) Abelian two‐form gauge theory with a single pseudoscalar field. The latter field (having the negative kinetic term

Trace and Axial Anomalies on Equal Footing
Advances in High Energy Physics, 2020 We discussed that for some particular nonsupersymmetric theories, a generalized symmetry that includes both the scale and axial transformations and leads to a single current may contain also a pseudoscalar term. The method, inspired by the superconformal

Dalitz analysis of the three-body charmless decays B+=>K+Pi+Pi- and B+=>K+K+K-
, 2004 We report results on the Dalitz analysis of three-body charmless B+=>K+Pi+Pi- and B+=>K+K+K- decays based on a 140 fb$^{-1}$ data sample collected with the Belle detector.
