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.

Analysis of the pseudoscalar hidden-charm tetraquark states with the QCD sum rules
Nuclear Physics B, 2022 In this work, we take all the color-antitriplet diquarks, such as the scalar, pseudoscalar, vector, axialvector and tensor diquarks, as the basic constituents to construct the local pseudoscalar four-quark currents without importing the explicit P-waves ...

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.

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 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 ...

ON THE COMPLEXION OF PSEUDOSCALAR MESONS [PDF]
International Journal of Modern Physics A, 2005 A strongly momentum-dependent dressed-quark mass function is basic to QCD. It is central to the appearance of a constituent-quark mass-scale and an existential prerequisite for Goldstone modes. Dyson-Schwinger equation (DSEs) studies have long emphasised this importance, and have proved that QCD's Goldstone modes are the only pseudoscalar mesons to ...

MSSM scenarios with a light CP-odd Higgs boson [PDF]
EPJ Web of Conferences, 2019 The possibility of the presence of a light pseudoscalar with the mass of 28 GeV in the MSSM Higgs sector extended by dimension-six operators is analyzed. The perturbative unitarity and vacuum stability constraints are discussed.

Backreaction of electromagnetic fields and the Schwinger effect in pseudoscalar inflation magnetogenesis [PDF]
Physical Review D, 2019 We study magnetogenesis in axion-like inflation driven by a pseudoscalar field $\phi$ coupled axially to the electromagnetic (EM) field $(\beta/M_{p})\phi F_{\mu\nu}\tilde{F}^{\mu\nu}$ with dimensionless coupling constant $\beta$.
