SCALAR AND PSEUDOSCALAR GLUEBALLS [PDF]

open access: yesInternational 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)

Pseudoscalar pole terms contributions to hadronic light-by-light corrections to the muonium hyperfine splitting [PDF]

open access: yes, 2002
The contribution of pseudoscalar pole diagrams to the hadronic light-by-light corrections of order alpha^3 E_F to the ground state hyperfine splitting in hydrogenic atom is calculated in the pseudoscalar pole terms approximation.

Heavy quark masses [PDF]

open access: yes, 1991
In the large quark mass limit, an argument which identifies the mass of the heavy-light pseudoscalar or scalar bound state with the renormalized mass of the heavy quark is given.

Two and three pseudoscalar production in e + e − annihilation and their contributions to (g − 2) μ

open access: yesJournal of High Energy Physics, 2021
A coherent study of e + e − annihilation into two (π + π − , K + K − ) and three (π + π − π 0 , π + π − η) pseudoscalar meson production is carried out within the framework of resonance chiral theory in energy region E ≲ 2 GeV. The work of [L.Y.

The light pseudoscalar Higgs boson in NMSSM [PDF]

open access: yes, 2006
We study the associated production of a very light pseudoscalar Higgs boson with a pair of charginos. The novel signature involves a pair of charged leptons from chargino decays and a pair of photons from the pseudoscalar Higgs boson decay, plus large ...

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.

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.

The a0(980) in the single Cabibbo-suppressed process Λc → π0ηp

open access: yesPhysics Letters B, 2023
In this work, we have investigated the Cabibbo-suppressed process Λc→π0ηp, by taking into account the intermediate scalar state a0(980), which could be dynamically generated from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary ...
