Abstract:
© 2018 Elsevier B.V. Active silicon detectors built on p-type substrate are a promising technological solution for large area silicon trackers such as those at the High Luminosity LHC, but the radiation hardness of this novel approach has to be evaluated. Active n-in-p strip detector prototypes CHESS2 for ATLAS with different substrate resistivities in the range of 20–1000 Ωcm were irradiated with neutrons and protons up to a fluence of 2×10 15 n eq cm −2 and 3.6×10 15 n eq cm −2 . Charge collection in passive test structures on the chip was evaluated using Edge-TCT and minimum ionising electrons from 90 Sr. Results were used to assess radiation hardness of the detector in the given fluence range and to determine parameters of initial acceptor removal in different substrates.Search for Higgs boson pair production in the $γγWW^{*}$ channel using $pp$ collision data recorded at $\sqrt{s} = 13$ TeV with the ATLAS detector

Abstract:
In the present paper, the ATLAS inclusive W± and Z boson production data are analyzed together with the CMS inclusive W± and Z boson production data to investigate any possible tensions between the data sets and to determine the strange sea fraction, within the framework of a parton distribution function fit at next-to next-to-leading order in perturbative QCD.Search for charged Higgs bosons decaying via $H^{\pm} \to τ^{\pm}ν_τ$ in the $τ$+jets and $τ$+lepton final states with 36 fb$^{-1}$ of $pp$ collision data recorded at $\sqrt{s} = 13$ TeV with the ATLAS experiment
