Rare hadronic B decays: probing deeper into the Standard Model [PDF]

open access: yes, 2003
We present recent results from the Belle experiment on rare hadronic B meson decays. The results are based on a 78 fb^{-1} data sample and consist of branching fractions, CP asymmetries, and polarization amplitudes.

Search for a low-mass pseudoscalar Higgs boson produced in association with a bb‾ pair in pp collisions at s=8 TeV

open access: yesPhysics 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

Doped holographic fermionic system

open access: yesEuropean 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.

Chiral Properties of Pseudoscalar Mesons on a Quenched $20^4$ Lattice with Overlap Fermions [PDF]

open access: yes, 2001
The chiral properties of the pseudoscalar mesons are studied numerically on a quenched $20^4$ lattice with the overlap fermion. We elucidate the role of the zero modes in the meson propagators, particularly that of the pseudoscalar meson.

Gluonic Correlations in Matter [PDF]

open access: yes, 2000
We derive the analogue of the QCD low energy theorems for the scalar and pseudoscalar gluonic correlators in nuclear matter. We find that the scalar correlations are depleted while the pseudoscalar correlations are enhanced to leading order in the ...

Chiral Lagrangian with higher resonances and flavour $ SU(3) $ breaking

open access: yes, 1993
A chiral Lagrangian with $ SU(3) $ breaking and higher resonances is proposed. In this model, the $ SU(3) $ breaking structure in vector-pseudoscalar sector is realized with the decay constants of pseudoscalar mesons and the masses of vector mesons used ...

INVESTIGATING PSEUDOSCALAR AND SCALAR DARK MATTER [PDF]

open access: yesInternational Journal of Modern Physics A, 2006
In this paper another class of Dark Matter candidate particles — the pseudoscalar and scalar light bosonic candidates — is discussed. Particular care is devoted to the study of the processes for their detection (which only involves electrons and photons/X-rays) in a suitable underground experimental setup.

Can the 126 GeV boson be a pseudoscalar?

open access: yes, 2012
We test the possibility that the newly-discovered 126 GeV boson is a pseudoscalar by examining the correlations among the loop-induced pseudoscalar decay branching fractions to $\gamma\gamma$, $ZZ^*$, $Z\gamma$, and $WW^*$ final states in a model ...

Magneto-optic effects of the cosmic microwave background

open access: yesNuclear Physics B, 2018
Generation of magneto-optic effects by the interaction of the CMB with cosmic magnetic fields is studied. Effects which generate polarization such as the Cotton–Mouton effect, vacuum polarization and photon–pseudoscalar mixing in external magnetic field ...
