Constructing new pseudoscalar meson nonets with the observed $X(2100)$, $X(2500)$ and $\eta(2225)$ [PDF]
, 2017 Stimulated by the BESIII observation of $\eta(2100)$, $X(2500)$ and $\eta(2225)$, we try to pin down new pseudoscalar meson nonets with these states. The mass spectrum analysis and strong decay study indicate that $X(2120)$ and $\eta(2225)$ associated ...

Is there a scalar or pseudoscalar at 95 GeV?
Physical Review DWe discuss the possibility of interpreting the recent experimental hints in favor of a 95 GeV resonance with extensions of the Standard Model featuring an extra Higgs doublet and SM scalar (2HDM+s) or pseudoscalar singlet (2HDM+a). We compare the possibility of reproducing the experimental anomalies with the theoretical constraints on the extended ...

Veneziano's Model for Pseudoscalar-Pseudoscalar Scattering, Factorization and the Nonet Ansatz [PDF]
Progress of Theoretical Physics, 1969 Crossing·symmetric, Regge behaved amplitudes of the Veneziano type are constructed for Ps-Ps scattering, where Ps denotes the pseudoscalar meson octet. Factorization of the parent and the first (odd) daughter Regge trajectories is investigated in detail.

Pseudoscalars in the charmonium model
Zeitschrift f�r Physik C Particles and Fields, 1980 We take the recently found charmonium state at 2.976 GeV to be the ηc and show that it can be included in a charmonium model with relativistic corrections which reproduces the s-wave spectrum, the leptonic widths Γ(V→e+ e−) and the p-wave splittings. The upsilon spectrum is discussed as are the effects of radial and pseudoscalar mixing.

Projective duality encodes complementary orientations in geometric algebras
Mathematical Methods in the Applied Sciences, Volume 47, Issue 14, Page 11422-11438, 30 September 2024.Oriented elements are part of geometry, and they come in two complementary types: intrinsic and extrinsic. Those different orientation types manifest themselves by behaving differently under reflection. Projective dualization in geometric algebras can encode them, or conversely, orientation types inform the interpretation of dualization.

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 ...

QCD corrections to production of Higgs pseudoscalars [PDF]
Physical Review D, 1994 Models of electroweak symmetry breaking with more than a single doublet of Higgs scalars contain a neutral pseudoscalar boson. The production of such a pseudoscalar in hadron collisions proceeds primarily via gluon fusion through a top-quark loop (except for those models in which the pseudoscalar coupling to bottom quarks is strongly enhanced).

Biosensing with Oleosin‐Stabilized Liquid Crystal Droplets
Small, Volume 20, Issue 31, August 1, 2024.Oleosins can stabilize nematic liquid crystal droplets for use in biological sensing, while chiral nematic liquid crystals can instead directly be used to sense the presence of oleosins. Abstract Liquid crystals (LCs) are emerging as novel platforms for chemical, physical, and biological sensing.
