Type-III two Higgs doublet model plus a pseudoscalar confronted with h→μτ, muon g−2 and dark matter

Nuclear Physics B, 2016
In this work, we introduce an extra singlet pseudoscalar into the Type-III two Higgs doublet model (2HDM) which is supposed to solve a series of problems in the modern particle-cosmology.

Observation of pseudoscalar and tensor resonances in J / ψ → γ ϕ ϕ [PDF]

, 2016
Based on a sample of (1310.6 +/- 10.5) x 10(6) J/psi events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/psi -> gamma phi phi is performed in order to study the intermediate states ...

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.

Distinguishing scalar from pseudoscalar Higgs production at the LHC

, 2002
In this letter we examine the production channels for the scalar or pseudoscalar Higgs plus two jets at the CERN Large Hadron Collider (LHC). We identify possible signals for distinguishing between a scalar and a pseudoscalar Higgs boson.Comment: 7 pages,

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

Universal properties of pseudoscalar mediators in dark matter extensions of 2HDMs

Journal of High Energy Physics, 2018
A bstractWe discuss universal signals of consistent models of pseudoscalar mediators for collider searches for Dark Matter. Keeping only the degrees of freedom that can not be decoupled due to consistency conditions, we present a universality class of ...
