Observation of chi(c2) -> eta 'eta ' and chi(c0,2) -> eta eta '

open access: yes, 2017
Using a sample of 448.1 x 10(6) Psi(3686) events collected with the BESIII detector in 2009 and 2012, we study the decays chi(c0,2) -> eta 'eta ' and eta eta '. The decays chi(c2) -> eta 'eta ', chi(c0) -> eta eta ' and chi(c2) -> eta eta ' are observed for the first time with statistical significances of 9.6 sigma, 13.4 sigma and 7.5 sigma ...

Observation of $\chi_{c2}\to\eta'\eta'$ and $\chi_{c0,2}\to\eta\eta'$

open access: yes, 2017
Using a sample of $447.9\times 10^6$ $\psi(3686)$ events collected with the BESIII detector in 2009 and 2012, we study the decays $\chi_{c0,2}\to$ $\eta'\eta'$ and $\eta\eta'$. The decays $\chi_{c2}\to\eta'\eta'$, $\chi_{c0}\to\eta\eta'$ and $\chi_{c2}\to\eta\eta'$ are observed for the first time with statistical significances of $9.6\sigma$, $13.4 ...

The eta -> eta(0)gamma gamma decay, the eta/eta ' mixing angle and the eta mass measurement at KLOE

open access: yes, 2006
We present preliminary results from the KLOE experiment on the Br(eta -> pi(0)gamma gamma), the ratio of the two branching fractions Br(phi -> eta'gamma)/Br(phi -> eta gamma) with the pi(+)pi(-)7 gamma final state and a preliminary measurement of the eta mass using the decay phi -> eta gamma, eta -> gamma gamma.

Building machine learning assisted phase diagrams: Three chemically relevant examples

open access: yesAIP Advances, 2022
In this work, we present a systematic procedure to build phase diagrams for chemically relevant properties by the use of a semi-supervised machine learning technique called uncertainty sampling.

Evidence of a Cenomanian shallow-marine carbonate platform in the northwestern margin of the Bortziriak-Cinco Villas massif, eastern Basque-Cantabrian Basin

open access: yesGeogaceta, 2023
Basin margin evolution of rift basins is not always well constrained. In the northeastern margin of the Basque-Cantabrian Basin, a revision of a carbonate succession permits deciphering the transition from synto post-rift phases in the poorly studied ...
