Dark-Sector Search via Pion-Produced η and η′ Mesons Decaying Invisibly in the NA64h Detector / NA64 Collaboration
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar η and η′ mesons in the NA64h experiment at the CERN SPS. Our novel technique uses the charge-exchange reaction of 50 GeV π- on nuclei of an active target as the source of neutral mesons. [...]

Search for Light Dark Matter with NA64 at CERN / NA64 Collaboration
Thermal dark matter models with particle $\chi$ masses below the electroweak scale can provide an explanation for the observed relic dark matter density. This would imply the existence of a new feeble interaction between the dark and ordinary matter. [...]

Search for a New $B$ - $L$ $Z'$ Gauge Boson with the NA64 Experiment at CERN / NA64 Collaboration
A search for a new $Z'$ gauge boson associated with (un)broken B-L symmetry in the keV-GeV mass range is carried out for the first time using the missing-energy technique in the NA64 experiment at the CERN SPS. From the analysis of the data with 3.22e11 electrons on target collected during 2016-2021 runs no signal events were found. [...]

Nucl. Problems) ; Solin, A V (Minsk, Inst. Nucl. Problems)
The aim of this work is to describe the characteristics and properties of the particle-tracking detectors created at the Joint Institute for Nuclear Research by the glued straw tube technology for the NA64 experiment on the extracted electron beam of the CERN SPS. The physical task of the experiment is to search for phenomena of the dark sector and dark matter..

The reconstruction of photons in the ATLAS detector is studied with data taken during the 2004 Combined Test Beam, where a full slice of the ATLAS detector was exposed to beams of particles of known energy at the CERN SPS. The results presented show significant differences in the longitudinal development of the electromagnetic shower between converted and unconverted photons as well as in the total measured energy.

Study of Jet Shapes in Inclusive Jet Production in pp Collisions at $\sqrt{s}$ = 7 TeV using the ATLAS Detector / ATLAS Collaboration
Jet shapes have been measured in inclusive jet production in proton-proton collisions at sqrt(s) = 7 TeV using 3 pb^{-1} of data recorded by the ATLAS experiment at the LHC. Jets are reconstructed using the anti-kt algorithm with transverse momentum 30 GeV < pT < 600 GeV and rapidity in the region |y| < 2.8. [...]

Measurement of the centrality dependence of $J/{\psi}$ yields and observation of Z production in lead-lead collisions with the ATLAS detector at the LHC / ATLAS Collaboration
Using the ATLAS detector, a centrality-dependent suppression has been observed in the yield of $J/{\psi}$ mesons produced in the collisions of lead ions at the Large Hadron Collider. In a sample of minimum-bias lead-lead collisions at a nucleon-nucleon centre of mass energy $\surd sNN$ = 2.76 TeV, corresponding to an integrated luminosity of about 6.7 ${\mu}b^{-1}$, $J/{\psi}$ mesons are reconstructed via their decays to ${\mu}+{\mu}-$ pairs.

Measurement of the inclusive isolated prompt photon cross section in pp collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the cross section for the inclusive production of isolated prompt photons in $pp$ collisions at a centre-of-mass energy $\sqrt(s)$ = 7 TeV is presented. The measurement covers the pseudorapidity ranges $|\eta^{\gamma}| < 1.37$ and $1.52 \leq |\eta^{\gamma}| < 1.81$ in the transverse energy range $15 \leq E^{\gamma}_T\ \leq 100~GeV$. [...]
