Spectrum of scalar and pseudoscalar glueballs from functional methods. [PDF]
Eur Phys J C Part Fields, 2020 We provide results for the spectrum of scalar and pseudoscalar glueballs in pure Yang–Mills theory using a parameter-free fully self-contained truncation of Dyson–Schwinger and Bethe–Salpeter equations.

Reconstructing a light pseudoscalar in the Type-X Two Higgs Doublet Model
Physics Letters B, 2017 We investigate the detectability as well as reconstructibility of a light pseudoscalar particle $A$, of mass in the 50 - 60 GeV range, which is still allowed in a Type-X (lepton-specific) two-Higgs doublet scenario.

Excited scalar and pseudoscalar mesons in the extended linear sigma model [PDF]
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.

Altermagnetism and magnetic groups with pseudoscalar electron spin [PDF]
Physical review B, 2022 We revise existing group-theoretical approaches for a treatment of nonrelativistic collinear magnetic systems with perfect translation invariance. We show that full symmetry groups of these systems, which contain elements with independent rotations in ...

On the constitutive pseudoscalars of hemitropic micropolar media in inverse coordinate frames [PDF]
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021 The paper is devoted to the constitutive pseudoscalars associated with the theory of hemitropic micropolar continuum. The basic concepts of pseudotensor algebra are presented. The pseudotensor form of the hemitropic micropolar elastic potential is given,

Neutron star observations of pseudoscalar-mediated dark matter [PDF]
Physical Review D, 2022 Scattering interactions between dark matter and Standard Model states mediated by pseudoscalars are generically challenging to uncover at direct detection experiments due to rates suppressed by powers of the local dark matter velocity v DM ∼ 10 − 3 c ...

Fermion singlet dark matter in a pseudoscalar dark matter portal [PDF]
Journal of High Energy Physics, 2021 We explore a simple extension to the Standard Model containing two gauge singlets: a Dirac fermion and a real pseudoscalar. In some regions of the parameter space both singlets are stable without the necessity of additional symmetries, then becoming a ...

Pseudoscalars and the η′ in the holographic soft-wall model [PDF]
EPJ Web of Conferences, 2022 Pseudoscalar mesons and glueballs are studied in a model based on the AdS/QCD correspondence. Glueball masses are obtained in the pure-gauge case, while the mixing between pseudoscalar glueballs and singlet pseudoscalar mesons produces the expected mass ...

Revealing the structure of light pseudoscalar mesons at the electron–ion collider [PDF]
, 2021 How the bulk of the Universe's visible mass emerges and how it is manifest in the existence and properties of hadrons are profound questions that probe into the heart of strongly interacting matter.

Nucleon axial-vector and pseudoscalar form factors, and PCAC relations [PDF]
, 2021 We use a continuum quark+diquark approach to the nucleon bound-state problem in relativistic quantum field theory to deliver parameter-free predictions for the nucleon axial and induced pseudoscalar form factors, $G_A$ and $G_P$, and unify them with the ...
