The Isgur-Wise Function: A Lattice Determination from Pseudoscalar --> Pseudoscalar Form Factors [PDF]
Nucl.Phys.Proc.Suppl.34:486-488,1994, 1993 Form factors for pseudoscalar --> pseudoscalar decays of heavy-light mesons are found in quenched lattice QCD with heavy-quark masses in the range of approximately 1-2 GeV. The Isgur-Wise function, $\xi(\omega)$, is extracted from these form factors. Results are in good agreement with $\xi(\omega)$ derived from CLEO measurements for B --> D*.

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.

Thermal quarkonium physics in the pseudoscalar channel [PDF]
Journal of High Energy Physics, 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.

Combined search for anomalous pseudoscalar HVV couplings in VH(H→bb‾) production and H→VV decay
Physics Letters B, 2016 A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (=W or Z) in a sample of proton–proton collision events corresponding to an integrated luminosity of 18.9 fb−1 at a center-of-mass energy of 8 TeV is ...

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 ...

Seed-Mediated Growth and Advanced Characterization of Chiral Gold Nanorods. [PDF]
Adv MaterRecent progress in bottom‐up wet‐chemical synthesis of gold nanoparticles has created remarkable opportunities to produce nanoparticles with well‐defined chiral shapes and strong chiroptical activities. This perspective focuses on the seed‐mediated synthesis of chiral gold nanorods as a convenient case of chiral morphogenesis.

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.

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 ...
