Primordial gravitational waves for universality classes of pseudoscalar inflation [PDF]
, 2016 Current bounds from the polarization of the CMB predict the scale-invariant gravitational wave (GW) background of inflation to be out of reach for upcoming GW interferometers. This prospect dramatically changes if the inflaton is a pseudoscalar, in which

On the Effective Hamiltonian for Pseudoscalar Meson with Pseudoscalar Coupling with Nucleon [PDF]
Progress of Theoretical Physics, 1954 The method of canonical transformation is applied to the pseudo-scalar meson theory with pseudoscalar coupling. It will be shown that tbe Tanj1)-Foldy~) transformation results as the best one when regarded as a variational function among the similar family of transformation.

Doped holographic fermionic system
European Physical Journal C: Particles and Fields, 2020 We construct a two-current model. It includes two gauge fields, which introduce the doping effect, and a neutral scalar field. And then we numerically construct an AdS black brane geometry with scalar hair.

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 ...

Physics Letters B, 2016 A search is reported for a light pseudoscalar Higgs boson decaying to a pair of τ leptons, produced in association with a bb‾ pair, in the context of two-Higgs-doublet models. The results are based on pp collision data at a centre-of-mass energy of 8 TeV

Decay of the pseudoscalar glueball and its first excited state into scalar and pseudoscalar mesons and their first excited states [PDF]
Phys. Rev. D 100, 096007 (2019), 2019 We expand the study of the pseudoscalar glueball and its first excited state by constructing an interaction Lagrangian which produces the two- and three-body decays of the pseudoscalar glueball, $J^{PC}=0^{-+}$, into the (pseudo)scalar and the excited (pseudo)scalar mesons as well as by constructing other two different chiral Lagrangians which describe

Strange and Charm Quark Spins from Anomalous Ward Identity [PDF]
, 2017 We present a calculation of the strange and charm quark contributions to the nucleon spin from the anomalous Ward identity (AWI). It is performed with overlap valence quarks on 2+1-flavor domain-wall fermion gauge configurations on a $24^3 \times 64 ...

SCALAR AND PSEUDOSCALAR GLUEBALLS [PDF]
International Journal of Modern Physics A, 2009 We employ two simple and robust results to constrain the mixing matrix of the isosinglet scalar mesons f0(1710), f0(1500), f0(1370): one is the approximate SU (3) symmetry empirically observed in the scalar sector above 1 GeV and confirmed by lattice QCD, and the other is the scalar glueball mass at 1710 MeV in the quenched approximation. In the SU (3)
