a0(980)–f0(980) mixing in χc1 decay [PDF]

EPJ Web of Conferences, 2019
We investigate the isospin breaking in the χc1→π0π+π−${\chi _{c1}} \to {\pi ^0}{\pi ^ + }{\pi ^ - }$ and χc1→π0π0η${\chi _{c1}} \to {\pi ^0}{\pi ^0}\eta $ decays and its relation to the a0(980) – f0(980) mixing, which was measured by the BESIII ...

Finite width effects in \phi radiative decays [PDF]

, 2002
The decay widths \phi \to \gamma f_0(980) and \phi \to \gamma a_0(980) are calculated taking into account the finite widths of the scalar resonances f_0(980) and a_0(980).

Charmless hadronic B decays involving scalar mesons: Implications to the nature of light scalar mesons [PDF]

, 2005
The hadronic charmless B decays into a scalar meson and a pseudoscalar meson are studied within the framework of QCD factorization. Although the light scalar mesons $f_0(980)$ and $a_0(980)$ are widely perceived as primarily the four-quark bound states ...

Role of scalar $$a_0(980)$$ a 0 ( 980 ) in the single Cabibbo suppressed process $$D^+ \rightarrow \pi ^{+} \pi ^{0} \eta $$ D + → π + π 0 η

European Physical Journal C: Particles and Fields, 2020
Taking into account that the scalar $$a_0(980)$$ a 0 ( 980 ) can be dynamically generated from the pseudoscalar-pseudoscalar interaction within the chiral unitary approach, we have studied the single Cabibbo suppressed process $$D^+\rightarrow \pi ^+\pi ^

Light meson decays at BESIII [PDF]

EPJ Web of Conferences, 2019
The BESIII experiment has accumulated the world’s largest data samples of 1.3 billion J/ψ events and 0.45 billion ψ(3686) events, which provide a unique opportunity to investigate light meson decays.

Cabibbo-favored Λc+→Λa0(980)+ decay in the final state interaction

Physics Letters B, 2021
The anti-triplet charmed baryon decays with the light scalar mesons are rarely measured, whereas the recent observation of the Cabibbo-favored Λc+→Ληπ+ decay hints a possible Λc+→Λa0(980)+,a0(980)+→ηπ+ process.
