Evidence for two-quark content of $f_{0}(980)$ in exclusive $b\to c$ decays [PDF]

, 2003
Inspired by a large decay branching ratio (BR) of $B^{+}\to f_{0}(980)K^{+}$ measured by Belle recently, we propose that a significant evidence of the component of $n\bar{n}=(u\bar{u}+d\bar{d})/\sqrt{2}$ in $f_{0}(980)$ could be demonstrated in exclusive

The a0(980) and f0(980) in the process Ds+→K+K−π+

Physics Letters B, 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.

Analysis the $f_0(980)$ and $a_0(980)$ mesons as four-quark states with the QCD sum rules

, 2005
In this article, we take the point of view that the scalar mesons $ f_0(980)$ and $a_0(980)$ are diquark-antidiquark states $(qq)_{\bar{3}}(\bar{q}\bar{q})_3$, and devote to determine their masses in the framework of the QCD sum rules approach with the ...

Observation of a00 (980)-f0 (980) Mixing

, 2018
We report the first observation of a00(980)-f0(980) mixing in the decays of J/???f0(980)??a00(980)????0 and ?c1?a00(980)?0?f0(980)?0??+?-?0, using data samples of 1.31×109 J/? events and 4.48×108 ?(3686) events accumulated with the BESIII detector.

Calculation of the $$B\rightarrow K_{0,2}^*(1430)f_0(980)/\sigma $$ B→K0,2∗(1430)f0(980)/σ decays in the perturbative QCD approach

European Physical Journal C: Particles and Fields, 2019
Motivated by the observations of the decays $$B^0 \rightarrow K_0^{*}(1430)^0 f_0(980)$$ B0→K0∗(1430)0f0(980) and $$ B^0 \rightarrow K_2^{*}(1430)^0 f_0(980)$$ B0→K2∗(1430)0f0(980) from BaBar collaboration, we study the $$B^{0(+)} \rightarrow K_{0,2}^{*}(

Measurement of $B^0\to\pi^+\pi^-\pi^+\pi^-$ Decays and Search for $B^0\to\rho^0\rho^0$

, 2008
We report on a search for the decay $B^0\to\rho^0\rho^0$ and other charmless modes with a $\pi^+\pi^-\pi^+\pi^-$ final state, including $B^0\to\rho^0\pi^+\pi^-$, non-resonant $B^0\to 4\pi^{\pm}$, $B^0\to\rho^0f_0(980)$, $B^0\to f_0(980)f_0(980)$ and $B^0\

Why the f(0)(980) is mostly ssbar [PDF]

, 2000
We exploit the W-emission process to study the measured weak decay of the D(s,+)(1.9686) meson into f(0)(980) and a positively charged pion. We conclude that the scalar f(0)(980) meson contains mostly strange-antistrange flavors, which is supported by ...
