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 ...

First lattice calculation of radiative leptonic decay rates of pseudoscalar mesons [PDF]
Physical Review D, 2020 We present a non-perturbative lattice calculation of the form factors which contribute to the amplitudes for the radiative decays $P\to \ell \bar \nu_\ell \gamma$, where $P$ is a pseudoscalar meson and $\ell$ is a charged lepton.

Nucleon axial and pseudoscalar form factors from lattice QCD at the physical point [PDF]
Physical Review D, 2020 We compute the nucleon axial and induced pseudoscalar form factors using three ensembles of gauge configurations, generated with dynamical light quarks with mass tuned to approximately their physical value.

Comparing 2HDM + scalar and pseudoscalar simplified models at LHC [PDF]
Journal of High Energy Physics, 2020 In this work we compare the current experimental LHC limits of the 2HDM + scalar and pseudoscalar for the t t ¯ $$ t\overline{t} $$ , mono- Z and mono- h signatures and forecast the reach of future LHC upgrades for the mono- Z channel.

Decay of the pseudoscalar glueball into scalar and pseudoscalar mesons [PDF]
Physical Review D, 2013 We study a chiral Lagrangian which describes the two- and three-body decays of a pseudoscalar glueball into scalar and pseudoscalar mesons. The various branching ratios are a parameter-free prediction of our approach. We compute the decay channels for a pseudoscalar glueball with a mass of 2.6 GeV, as predicted by Lattice QCD in the quenched ...

On the Definition of Chirality and Enantioselective Fields
Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022 Abstract In solid state physics, any symmetry breaking is known to be associated with emergence of an order parameter. However, the order parameter for molecular and crystal chirality, which is a consequence of parity and mirror symmetry breaking, has not been known since its discovery.

The pseudoscalar decay constant [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 We discuss insights that may be drawn from our recent 2 flavour O(a)--improved Wilson quark simulations. We discuss the evidence of the onset of chiral logarithms in the pion decay constant. An overview is given of current extrapolation methods and a modification of chiral perturbation theory is presented as an approach for sensibly extrapolating to ...

On the Neuber theory of micropolar elasticity. A pseudotensor formulation
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020 The present paper deals with a pseudotensor formulation of the Neuber theory of micropolar elasticity. The dynamic equations of the micropolar continuum in terms of relative tensors (pseudotensors) are presented and discussed.

On a micropolar theory of growing solids
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020 The present paper is devoted to the problem of boundary conditions formulation in the growing micropolar solid mechanics. The static equations of the micropolar continuum in terms of relative tensors (pseudotensors) are derived due to virtual work ...
