Light Scalar Mesons from Phi to Psi [PDF]

open access: yes, 2006
The following topics are considered. 1) Confinement, chiral dynamics, and light scalar mesons. 2) Chiral shielding of the $\sigma(600)$. 3) The $\phi$ meson radiative decays about nature of light scalar resonances.

Study a0(980)-f0(980) mixing from a0(980) -> f0(980) transition

open access: yes, 2008
Various processes have been proposed previously to study a0(980)-f0(980) mixing through f0(980)->a0(980) transition. Here we investigate in detail the difference between a0(980)->f0(980) and f0(980)->a0(980) transitions. It is found that the a0(980)->f0(980) transition can provide additional constrains to the parameters of a0(980) and f0 ...

Study the CP violation of the quasi-two-body decays of B meson with the a00(980) and f0(980) mixing

open access: yesNuclear Physics B, 2023
In the framework of the QCD factorization approach, we study the localized CP violations of the B−→K−π+π−, B−→π−π+π−, B−→K−K+K−, B−→π−K+K−, B−→K−π0η and B−→π−π0η decays with and without the a00(980)−f0(980) mixing mechanism, respectively, and find that ...

f0(980) production in inelastic pp collisions at s = 5.02 TeV

open access: yesPhysics Letters B, 2023
The measurement of the production of f0(980) in inelastic pp collisions at s=5.02 TeV is presented. This is the first reported measurement of inclusive f0(980) yield at LHC energies. The production is measured at midrapidity, |y|

New information on the strong isospin symmetry breaking in the reactions of the a00(980) and f0(980) resonance production [PDF]

open access: yesEPJ Web of Conferences, 2019
We discuss the isotopic symmetry breaking as a tool of studying the production mechanisms and nature of light scalar mesons. The anomalous isospin breaking effects can appear not only due to the a00(980)−f0(980)$ a_0^0(980) - {f_0}(980) $ mixing, but ...

Manifestations of the $a^0_0(980)-f_0(980)$ mixing in $D^0\to K^0_S\pi^+\pi^-$ and $D^0\to K^0_S\eta\pi^0$ decays

open access: yes, 2017
Possible manifestations of the isospin-breaking mixing of the $a^0_0(980)$ and $f_0(980)$ resonances are analyzed in the $D^0\to K^0_S \pi^+\pi^-$ and $D^0\to K^0_S\eta\pi^0$ decays.

First measurement of direct $f_0(980)$ photoproduction on the proton [PDF]

open access: yes, 2008
We report on the results of the first measurement of exclusive $f_0(980)$ meson photoproduction on protons for $E_\gamma=3.0 - 3.8$ GeV and $-t = 0.4-1.0$ GeV$^2$.

The scalar $$f_0(500)$$ f 0 ( 500 ) , $$f_0(980)$$ f 0 ( 980 ) , and $$a_0(980)$$ a 0 ( 980 ) resonances and vector mesons in the single Cabibbo-suppressed decays $$\Lambda _c \rightarrow p K^+K^-$$ Λ c → p K + K - and $$p\pi ^+\pi ^-$$ p π + π -

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In the chiral unitary approach, we have studied the single Cabibbo-suppressed decays $$\Lambda _c\rightarrow pK^+K^-$$ Λ c → p K + K - and $$\Lambda _c \rightarrow p \pi ^+\pi ^-$$ Λ c → p π + π - by taking into account the s-wave meson–meson interaction

Radiative decays of basic scalar, vector and tensor mesons and the determination of the P-wave q\bar q multiplet

open access: yes, 2001
We perform simultaneous calculations of the radiative decays of scalar mesons f_0(980)-> \gamma\gamma, a_0(980)-> \gamma\gamma, vector meson \phi(1020)-> \gamma f_0(980), \gamma a_0(980), \gamma \pi^0, \gamma \eta, \gamma \eta' and tensor mesons a_2(1320)

The (980) and (980) in the Process

open access: yesPhysics Letters, 2021
In this work, we have investigated the process Ds+→K+K−π+, taking into account the contributions from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary approach, and also the intermediate ϕ resonance. By analyzing the BESIII and BABAR measurements, we conclude that the f0(980) state, dynamically generated from the S-wave ...
