Excitation Spectra of the ${}^{12}{\rm C}(p,d)$ Reaction near the $η'$-Meson Emission Threshold Measured in Coincidence with High-Momentum Protons Open
The missing mass of the ${}^{12}{\rm C}(p,d)$ reaction has been measured near the $η'$-meson emission threshold in coincidence with a high-momentum proton to selectively collect $η'$-${}^{11}{\rm C}$ mesic nucleus formation events at GSI, …

Studies of three-and four-body hypernuclei with heavy-ion beams, nuclear emulsions and machine learning Open
Interests on few-body hypernuclei have been increased by recent results of experiments employing relativistic heavy ion beams. Some of the experiments have revealed that the lifetime of the lightest hypernucleus, hypertriton, is significan…

Study of light hypernuclei in Europe: The hypertriton and nnΛ puzzles Open
The current understanding of light hypernuclei, which are sub-atomic nuclei with strangeness, is being challenged and studied in detail by several European research groups and collaborations. In recent years, studies of hypernuclei using h…

A new measurement on <sup>56</sup>Fe(n,inl) using GAINS@GELINA Open
The extended dataset of 56 Fe(n,n’γ) cross sections measured by our group more than a decade ago at GELINA (Geel Linear Accelerator) was used in many recent evaluations like ENDF, JEFF and CIELO. Despite the special measures we took to ens…

Observation of the helicity-selection-rule suppressed decay of the $χ_{c2}$ charmonium state Open
The decays of $χ_{c2}\to K^{+}K^{-}π^{0}$, $K_{S} K^{\pm}π^{\mp}$ and $π^{+}π^{-}π^{0}$ are studied with the $ψ(3686)$ data samples collected with the Beijing Spectrometer (BESIII). For the first time, the branching fractions of $χ_{c2}\to…

Improved measurements of branching fractions for $η_c\toϕϕ$ and $ωϕ$ Open
Using $(223.7\pm1.4)\times10^6$ J/$ψ$ events accumulated with the BESIII detector, we study $η_c$ decays to $ϕϕ$ and $ωϕ$ final states. The branching fraction of $η_c\toϕϕ$ is measured to be $Br(η_c\toϕϕ)=(2.5\pm0.3^{+0.3}_{-0.7}\pm0.6)\ti…
