The Ds+→π+KS0KS0 reaction and the I=1 partner of the f0(1710) state

L. R. Dai et al.

Summary: In this study, the decay modes of the D-s(+) decay producing a pion and two vector mesons were identified. Two resonances associated with the f(0)(1710) and a(0)(1710) were generated through posterior vector-vector interaction and decayed into the observed K+K- or (KSKS0)-K-0 pair. The study also determined parameters consistent with experimental results and predicted the branching ratio of the a(0)(1710) contribution to the D-s(+)->pi(K+KS0)-K-0 reaction.

Observation of an a0-like State with Mass of 1.817 GeV in the Study of DS+ → KS0K+ π0 Decays

M. Ablikim et al.

Summary: Using data from e(+)e(-) annihilation, we performed an amplitude analysis on the decay D-s(+) -> (KSK+)-K-0 pi(0) and determined the relative branching fractions and phases for intermediate processes. We observed a new state with a mass of 1.817 GeV decaying to (KSK+)-K-0 for the first time. Additionally, we measured the ratio of the branching fractions and provided a precision measurement of the absolute branching fraction.

Roles of a0(980), ?(1670), andS(1385) in the ?c+ ? ??p+ decay

Guan-Ying Wang et al.

Summary: Recently, the Belle Collaboration has measured the lambda(+)(c) -> eta lambda pi(+ )decay and observed clear signals of the resonances A(1670) and E(1385). By reanalyzing the process and considering the S-wave eta A and eta pi+ final state interactions, researchers have obtained results that are consistent with the experimental measurements.

Newly observed a0(1817) as the scaling point of constructing the scalar meson spectroscopy

Dan Guo et al.

Summary: Stimulated by the newly observed a(0)(1817) by the BESIII Collaboration, this study proposes a scheme for constructing the scalar meson family based on observed scalar states. Two Regge trajectories are identified and the third radial excitation is predicted. The study has important implications for understanding the properties of scalar mesons.

Theoretical study of the process Ds+ → π+ KS0KS0 and the isovector partner of f0(1710)

Xin Zhu et al.

Summary: This study presents a theoretical analysis of a(0)(1710), which is the isovector partner of f(0)(1710), in the process D-s(+) pi(+)-+(KSKS0)-K-0. The authors investigate the weak interaction part through the charm quark decay process and the hadronization part through different mechanisms. The results provide valuable insights into the nature of scalar f(0)(1710) and its isovector partner a(0)(1710).

Two dynamical generated a0 resonances by interactions between vector mesons

Zheng-Li Wang et al.

Summary: In this study, dynamically generated a(0) resonances are investigated using a coupled-channel approach, with interactions between vector mesons and their coupling to pseudoscalar meson channels. The results reveal the existence of a(0)(1710) as a coupled-channel dynamically generated state near the K*(K) over bar* threshold, as well as the possibility of a(0)(1450) being dynamically generated by rho omega interactions involving pi and eta exchange.

Study of the decay Ds+→ KS0KS0π+ and observation of an isovector partner to f0 (1710)

M. Ablikim et al.

Summary: In this study, an amplitude analysis of the decay D-s(+) -> (KSKS0)-K-0 pi(+) is performed using e(+)e(-) annihilation data collected with the BESIII detector. An enhancement near 1.7 GeV/c(2) is observed in the K(S)(0)K(S)(0) mass spectrum, suggesting the existence of an isospin one partner of the f(0)(1710). The branching fraction of the decay D-s(+) -> (KSKS0)-K-0 pi(+) is determined to be B(D-s(+) -> (KSKS0)-K-0 pi(+)) = (0.68 +/- 0.04(stat) +/- 0.01(syst))%.

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

Jun-Ya Wang et al.

Summary: In this study, the process D-s(+) -> K+ K-pi(+) was investigated, considering the contributions from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary approach and the intermediate phi resonance. The dynamically generated f(0)(980) state was found to give the dominant contribution near the K+ K- threshold in the invariant mass distribution of the decay. Our results suggest that the lineshape adopted for the resonances a(0)(980) and f(0)(980) by BESIII and BABAR may not be suitable for fitting data close to the K+ K- threshold.

Further study of f0(1710) with the coupled-channel approach and the hadron molecular picture

Zheng-Li Wang et al.

Summary: The study shows that although the pole assigned to f(0) (1710) does not change much, the ratios of partial decay widths calculated under different models still agree fairly with experimental values in both cases.

Summary: In this study, decay processes gamma gamma -> eta(c)-> eta'K+K-, eta'pi(+)pi(-), and eta pi(+)pi(-) were investigated using data from the BABAR detector at SLAC PEP-II collider. New branching fractions and resonances were measured, providing insights into scalar mesons and potential identification of the scalar glueball.

Amplitude analysis and branching fraction measurement of Ds+ → K+K-π+

M. Ablikim et al.

Summary: In this study, an amplitude analysis and branching fraction measurement of D-s(+) -> K+K-pi(+) decay were conducted using a data sample recorded with the BESIII detector. The absolute branching fraction was measured to be (5.47 +/- 0.08(stat) +/- 0.13(sys))%, based on the amplitude analysis results with a high purity and statistics sample.

Can the nature of a0(980) be tested in the Ds+. π+ π0η decay?

Xi-Zhe Ling et al.

Summary: The study suggests that the D-s(+) decay may proceed via internal and external W-emission mechanisms instead of the W-annihilation mechanism, proposing a new interpretation for the D-s(+) -> pi(+) pi(0)eta decay. Experimental data show that the intermediate state a(0)(980) can be dynamically generated, supporting its interpretation as a molecular state.
