Title: Observation of a Resonant Structure in e + e − → K + K − π 0 π 0

Abstract

A partial-wave analysis is performed for the process $e^+ e^– → K^+ K^– π^0π^0$ at the center-of-mass energies ranging from 2.000 to 2.644 GeV. The data samples of $e^+ e^–$ collisions, collected by the BESIII detector at the BEPCII collider with a total integrated luminosity of 300 pb–1 , are analyzed. The total Born cross sections for the process $e^+ e^– → K^+ K^– π^ 0π^0$, as well as the Born cross sections for the subprocesses $$e^+ e^– → \phi π^0 π^0, K^+(1460)K^–, K^+_1(1400)K^–, K^+_1(1270)K^–,$$ and $$K^{\ast+} (892)K^{\ast–}(892)$$, are measured versus the center-of-mass energy. The corresponding results for $e^+ e^– → K^+ K^– π^0π^0$ and $$\phiπ^0π^0$$ are consistent with those of $$\textit{BABAR}$$ with better precision. By analyzing the cross sections for the four subprocesses, $$K^+ (1460)K^–, K^+_1(1400)K^–, K^+_1(1270)K^–$$, and $$K^{\ast+}(892)K^{\ast–}(892)$$, a structure with mass $$\textit{M}$$ = ( 2126.5 ± 16.8 ± 12.4 ) MeV /$c^2$ and width Γ = ( 106.9 ± 32.1 ± 28.1 ) MeV is observed with an overall statistical significance of 6.3σ, although with very limited significance in the subprocesses $$e^+ e^– → K^+_1(1270)K^–$$ and $$K^{\ast} + (892)K^{\ast–}(892)$$. The resonant parameters of the observed structure suggest it can be identified with the $$\phi(2170)$$, thus the results provide valuable input to the internal nature of the $$\phi(2170)$$.

abstractNote = {A partial-wave analysis is performed for the process $e^+ e^– → K^+ K^– π^0π^0$ at the center-of-mass energies ranging from 2.000 to 2.644 GeV. The data samples of $e^+ e^–$ collisions, collected by the BESIII detector at the BEPCII collider with a total integrated luminosity of 300 pb–1 , are analyzed. The total Born cross sections for the process $e^+ e^– → K^+ K^– π^ 0π^0$, as well as the Born cross sections for the subprocesses $e^+ e^– → \phi π^0 π^0, K^+(1460)K^–, K^+_1(1400)K^–, K^+_1(1270)K^–,$ and $K^{\ast+} (892)K^{\ast–}(892)$, are measured versus the center-of-mass energy. The corresponding results for $e^+ e^– → K^+ K^– π^0π^0$ and $\phiπ^0π^0$ are consistent with those of $\textit{BABAR}$ with better precision. By analyzing the cross sections for the four subprocesses, $K^+ (1460)K^–, K^+_1(1400)K^–, K^+_1(1270)K^–$, and $K^{\ast+}(892)K^{\ast–}(892)$, a structure with mass $\textit{M}$ = ( 2126.5 ± 16.8 ± 12.4 ) MeV /$c^2$ and width Γ = ( 106.9 ± 32.1 ± 28.1 ) MeV is observed with an overall statistical significance of 6.3σ, although with very limited significance in the subprocesses $e^+ e^– → K^+_1(1270)K^–$ and $K^{\ast} + (892)K^{\ast–}(892)$. The resonant parameters of the observed structure suggest it can be identified with the $\phi(2170)$, thus the results provide valuable input to the internal nature of the $\phi(2170)$.},
