A search for charged leptons with large impact parameters using 139 fb$^{-1}$ of $\sqrt{s} = 13$ TeV $pp$ collision data from the ATLAS detector at the LHC is presented, addressing a long-standing gap in coverage of possible new physics signatures. Results are consistent with the background prediction. [...]

The paper presents a measurement of the Standard Model Higgs Boson decaying to $b$-quark pairs in the vector boson fusion (VBF) production mode. A sample corresponding to 126 fb$^{-1}$ of $\sqrt{s} =$ 13 TeV proton-proton collision data, collected with the ATLAS experiment at the Large Hadron Collider, is analyzed utilizing an adversarial neural network for event classification.

Die Helmholtz-Gemeinschaft hat 2016 beschlossen, dass zum Stichtag 31.12.2020 60% aller Publikationen als Open Access (OA) verfügbar gemacht werden sollen, welches dann für jedes weitere Jahr um 10% gesteigert werden soll. Um diese Vorgabe umzusetzen, hat DESY mit dem Publikationsserver PubDB schon frühzeitig angefangen, wo immer möglich Publikationen für OA zugänglich zu machen. [...]

This paper presents a search for dark matter in the context of a two-Higgs-doublet model together with an additional pseudoscalar mediator, $a$, which decays into the dark-matter particles. Processes where the pseudoscalar mediator is produced in association with a single top quark in the 2HDM+$a$ model are explored for the first time at the LHC. [...]

A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W$, $Z$, or Higgs boson. The trilepton invariant-mass spectrum is constructed from events with three or more leptons, targeting chargino decays that include an electron or muon and a leptonically decaying $Z$ boson. [...]
