Abstract

The ALICE experiment at CERN will propose unprecedented requirements for event building and data recording. New technologies will be adopted as well as ad-hoc frameworks, from the acquisition of experimental data up to the transfer onto permanent media and its later access. These issues justify a careful, in-depth planning and preparation. The ALICE Data Challenge is a very important step of this development process where simulated detector data is moved from dummy data sources up to the recording media using processing elements and data-paths as realistic as possible. We will review herein the current status of past, present and future ALICE Data Challenges, with particular reference to the sessions held in 2002 when - for the first time - streams worth one week of ALICE data were recorded onto tape media at sustained rates exceeding 300 MB/s.

First measurement of the masses of the $Υ_1(1D)$ and $Υ_3(1D)$ states and the energy dependence of the cross sections for $e^+e^-\toΥ_J(1D)η$ and $e^+e^-\toΥ_J(1D)π^+π^-$

We study the processes $e^+e^-\toΥ_J(1D)η$ and $e^+e^-\toΥ_J(1D)π^+π^-$ at center-of-mass energies $\sqrt{s}$=(10.73 -- 11.02) GeV using a $142.5\,\mathrm{fb}^{-1}$ data sample, including 122~fb$^{-1}$ near the $Υ$(10860) peak ($\sqrt{s}$ = 10.866 GeV), collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. From the peak sample, the products of Born cross section times branching fraction are obtained for $σ_{\rm Born}(e^+e^-\toΥ_J(1D)η)$ or $σ_{\rm Born}(e^+e^-\toΥ_J(1D)π^+π^-)$ and ${\cal B}(Υ_J(1D)\toχ_{b1}γ)$ or ${\cal B}(Υ_J(1D)\toχ_{b2}γ)$ for each $Υ_J(1D)$ state. The corresponding branching fractions for $Υ(10860)$ decays are also obtained. The significances of the $Υ_1(1D)$, $Υ_2(1D)$, and $Υ_3(1D)$ signals are 4.8$σ$, ${>}10σ$, and 3.0$σ$, respectively, including systematic uncertainties. The mass for $Υ_2(1D)$ is measured to be $(10167.0\pm 1.0\pm 0.2)$ MeV/$c^2$, where the first and second uncertainties are statistical and systematic. The mass splittings $Δm_{12}=m(Υ_2(1D))-m(Υ_1(1D))$ and $Δm_{23}=m(Υ_3(1D))-m(Υ_2(1D))$ are $(11.8\pm1.5\pm0.4)$ MeV/$c^2$ and $(7.6\pm2.4\pm0.6)$ MeV/$c^2$, respectively.~We determine the energy dependence of the cross sections for $e^+e^-\toΥ_J(1D)η$ and $e^+e^-\toΥ_J(1D)π^+π^-$ for the $Υ_1(1D)$, $Υ_2(1D)$, and $Υ_3(1D)$ states, combined.

Dark sector searches at BESIII

Large samples of charmonia, charm mesons, hyperons and light mesons collected by BESIII offer sensitive tests of dark sector interactions with charm and light quarks. This contribution reviews recent searches for sub-GeV dark matter in $η\toπ^0+\mathrm{invisible}$ and $J/ψ\toϕ+\mathrm{invisible}$, massless dark photons in $D^0\toωγ'$ and $D^0\toγγ'$, invisible $K^0_S$ decays, dark baryons in $Ξ^-\toπ^-χ$, and light vector bosons in $χ_{cJ}\to J/ψV$, $V\to e^+e^-$. Particular attention is given to the $η$ search, which constrains scalar-mediated dark matter and tests thermal relic benchmarks.

Dark-field Search for Quantum Vacuum Signals in the Low-Energy Regime

We report on the experimental details of a dark-field search for light-by-light scattering signals performed at the High Energy Density (HED) instrument of the European XFEL (EuXFEL) in a pump-probe type experiment colliding the EuXFEL beam with the 300-TW-class near-infrared Relativistic Laser at XFEL (ReLaX) at a center-of-mass photon energy of $ω_\star = 116\,\mathrm{eV}$. Especially in combination with polarization filtering, the dark-field concept allows the signal-to-background ratio to be significantly enhanced and both polarization channels to be recorded. This work elaborates on the experimental setup and the diagnostics used, from the per-shot spatiotemporal-overlap diagnostics, via the polarizing beam splitter, to the characterization of the residual background. Moreover, it provides details on the start-to-end simulations of the setup used for analysis. Accumulating 2751 pump-probe collisions, no excess above background is observed, and an upper limit on the light-by-light scattering cross section of $7\times10^{4}$ times the QED prediction at a 95% confidence level is derived. This is the most stringent bound on low-energy light-by-light scattering achieved to date, representing an improvement by ten orders of magnitude upon previous experimental limits.
