openCost: Automatisierte, standardisierte Lieferung und offene Bereitstellung von Publikationskosten und Verlagsvereinbarungen : Zwischenbericht zum DFG-Projekt Nr. 457354095
13 pp. () [10.3204/PUBDB-2025-00973]  GO
Within the scope of openCost we are creating a technical infrastructure that allows us to comprehensively record all costs involved in scientific publishing and subsequently make them freely accessible by means of standardized interfaces. This will enable cost transparency on an institutional, national, and international level.Therefore, with the support of (inter-)national experts, we have developed a standardized metadata schema to record, retrieve and map all publication costs of a scientific institution in a structured form.

Prospects for a search for direct pair production of top squarks at the high-luminosity LHC with the ATLAS detector
26 pp. () [10.3204/PUBDB-2024-07917]  GO
Prospects for a future search for direct pair production of top squarks (stop) in events with two opposite-charge leptons (electrons or muons), jets and missing transverse momentum at the HL-LHC are investigated in this note. The region of small mass-splitting between the stop and the lightest neutralino Δm(~t1,~χ01), where the stop proceeds through a four-body or three-body decay, without the presence of an on-shell top quark, is studied, and finally the analysis is also applied to the two-body decay region, where Δm(~t1,~χ01)>m(t).

Studies of matrix element correction in t\bar{t} events using MG5_aMC@NLO+Pythia8
[ATL-PHYS-PUB-2024-002]
7 pp. () [10.3204/PUBDB-2024-07916]  GO
We discuss the effect of matrix element corrections (MEC) to parton showers for t\bar{t} events usings the MG5_aMC@NLO + Pythia8 event generators. The studies are done for inclusive \ttbar production as well as for a setupusing the FxFx procedure with up to 2 additional jets in the matrix element. [...]

Reinterpretation of electroweak supersymmetry searches with final states containing taus in models of variable $R$-parity-violating coupling strength
[ATL-PHYS-PUB-2024-007]
15 pp. () [10.3204/PUBDB-2024-07914]  GO
Two ATLAS searches for supersymmetric particles in final states with multiple leptons, optimized for $R$-parity-conserving and $R$-parity-violating models, are reinterpreted in models with variable $R$-parity-violating couplings. The simplified models of pair-produced staus and pair-produced higgsinos are considered. [...]

Limits on long-lived chargino production using large specific ionisation and low-β in 140fb$^{−1}$ of pp collisions at $\sqrt{s}$ = 13 TeV using the ATLAS experiment
[ATL-PHYS-PUB-2024-009]
11 pp. () [10.3204/PUBDB-2024-07913]  GO
This note reinterprets a search utilising large specific ionisation in the pixel detector and the time-of-flight to the hadron calorimeter of the ATLAS detector at the LHC using an integrated luminosity of 140fb$^{−1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV. The signal considered is production of pure wino, anomaly-mediated-SUSY-breaking-like charginos. [...]

Monte Carlo Validation in ATLAS with PAVER
[ATL-PHYS-PUB-2024-013]
9 pp. () [10.3204/PUBDB-2024-07911]  GO
A dedicated validation of new Monte Carlo (MC) versions is essential in order to detect potential issues before launching large-scale MC production campaigns for the ATLAS collaboration in an effective and sustainable way. An automated, robust validation system named PMG Architecture for Validating Evgen with Rivet (PAVER) was developed for this purpose. [...]

Transformer networks for constituent-based $b$-jet calibration with the ATLAS detector
[ATL-PHYS-PUB-2024-015]
29 pp. () [10.3204/PUBDB-2024-07910]  GO
The precise measurement of a jet’s kinematics is a critical component of the physics program based on proton–proton collision data recorded by the ATLAS detector at the Large Hadron Collider. The determination of the energy and mass of jets containing bottom quarks $b$-jets is particularly difficult as, for example, they have different radiation patterns compared to the average jet and can contain heavy-flavour decays into a charged lepton and an unobserved neutrino.

Updated projection of the sensitivity of searches for Higgs boson pair production in the $b\bar{b}\tau^{+}\tau^{-}$ final state from LHC Run 2 to the High Luminosity LHC with the ATLAS detector
[ATL-PHYS-PUB-2024-016]
29 pp. () [10.3204/PUBDB-2024-07909]  GO
An updated projection of the sensitivity to non-resonant Higgs boson pair production in the $b\bar{b}\tau^{+}\tau^{-}$ final state from LHC Run 2 to the High Luminosity LHC with the ATLAS detector is presented. Sensitivites are projected assuming a centre-of-mass energy of $14\,\text{TeV}$ for a variety of integrated luminosities ranging from $1000$ to $3000\,\text{fb}^{-1}$. [...]
