Differential cross-section measurements of D± and Ds± meson production in proton-proton collisions at s = 13 TeV with the ATLAS detector
, Journal of High Energy Physics, Vol: 2025The production of D<sup>±</sup> and Ds± charmed mesons is measured using the D<sup>±</sup>/Ds±→ ϕ(μμ)π<sup>±</sup> decay channel with 137 fb<sup>−1</sup> of s = 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider during the years 2016–2018. The charmed mesons are reconstructed in the range of transverse momentum 12 < p<inf>T</inf> < 100 GeV and pseudorapidity |η| < 2.5. The differential cross-sections are measured as a function of transverse momentum and pseudorapidity, respectively, and compared with next-to-leading- order QCD predictions. The predictions are found to be consistent with the measurements in the visible kinematic region within the large theoretical uncertainties.

New Constraints on Cosmic Ray-Boosted Dark Matter from the LUX-ZEPLIN Experiment.
, Phys Rev Lett, Vol: 134While dual-phase xenon time projection chambers have driven the sensitivity toward weakly interacting massive particles at the GeV/c^{2} to TeV/c^{2} mass scale, the scope for sub-GeV/c^{2} dark matter particles is hindered by a limited nuclear recoil energy detection threshold. One approach to probe for lighter candidates is to consider cases where they have been boosted by collisions with cosmic rays in the Milky Way, such that the additional kinetic energy lifts their induced signatures above the nominal threshold. In this Letter, we report first results of a search for cosmic ray-boosted dark matter (CRDM) with a combined 4.2 metric ton/yr exposure from the LUX-ZEPLIN experiment. We observe no excess above the expected backgrounds and establish world-leading constraints on the spin-independent CRDM-nucleon cross section as small as 3.9×10^{-33} cm^{2} at 90% confidence level for sub-GeV/c^{2} masses.

Improved reconstruction of highly boosted τ-lepton pairs in the ττ→(μνμντ)(hadrons+ντ) decay channels with the ATLAS detector
, European Physical Journal C, Vol: 85, ISSN: 1434-6044This paper presents a new τ-lepton reconstruction and identification procedure at the ATLAS detector at the Large Hadron Collider, which leads to significantly improved performance in the case of physics processes where a highly boosted pair of τ-leptons is produced and one τ-lepton decays into a muon and two neutrinos (τμ), and the other decays into hadrons and one neutrino (τhad). By removing the muon information from the signals used for reconstruction and identification of the τhad candidate in the boosted pair, the efficiency is raised to the level expected for an isolated τhad. The new procedure is validated by selecting a sample of highly boosted Z→τμτhad candidates from the data sample of 140 fb-1 of proton–proton collisions at 13 TeV recorded with the ATLAS detector. Good agreement is found between data and simulation predictions in both the Z→τμτhad signal region and in a background validation region. The results presented in this paper demonstrate the effectiveness of the τhad reconstruction with muon removal in enhancing the signal sensitivity of the boosted τμτhad channel at the ATLAS detector.

The performance of missing transverse momentum reconstruction and its significance with the ATLAS detector using 140 fb-1 of s=13 TeV pp collisions
, European Physical Journal C, Vol: 85, ISSN: 1434-6044This paper presents the reconstruction of missing transverse momentum (pTmiss) in proton–proton collisions, at a center-of-mass energy of 13 TeV. This is a challenging task involving many detector inputs, combining fully calibrated electrons, muons, photons, hadronically decaying τ-leptons, hadronic jets, and soft activity from remaining tracks. Possible double counting of momentum is avoided by applying a signal ambiguity resolution procedure which rejects detector inputs that have already been used. Several pTmiss ‘working points’ are defined with varying stringency of selections, the tightest improving the resolution at high pile-up by up to 39% compared to the loosest. The pTmiss performance is evaluated using data and Monte Carlo simulation, with an emphasis on understanding the impact of pile-up, primarily using events consistent with leptonic Z decays. The studies use 140fb-1 of data, collected by the ATLAS experiment at the Large Hadron Collider between 2015 and 2018. The results demonstrate that pTmiss reconstruction, and its associated significance, are well understood and reliably modelled by simulation. Finally, the systematic uncertainties on the soft pTmiss component are calculated. After various improvements the scale and resolution uncertainties are reduced by up to 76% and 51%, respectively, compared to the previous calculation at a lower luminosity.
