Measurement of the $t \bar{t}$ production cross-section in $pp$ collisions at $\sqrt{s}=5.02$ TeV with the ATLAS detector
The inclusive top-quark pair ($t\bar{t}$) production cross-section $\sigma_{t\bar{t}}$ is measured in proton-proton collisions at a centre-of-mass energy $\sqrt{s}=5.02$ TeV, using 257 pb$^{-1}$ of data collected in 2017 by the ATLAS experiment at the LHC. [...]

BSM Targets at a Target-less DUNE / Bhattarai, Aayush (Texas U., Arlington) ; Brdar, Vedran (Fermilab ; Northwestern U.) ; Dutta, Bhaskar (Texas A-M) ; Jang, Wooyoung (Texas U., Arlington) ; Kim, Doojin (Texas A-M) ; Shoemaker, Ian M. (Virginia Tech.) ; Tabrizi, Zahra (Northwestern U.) ; Thompson, Adrian (Texas A-M) ; Yu, Jaehoon (Texas U., Arlington ; CERN)
In this Letter we demonstrate that a future accelerator-based neutrino experiment such as DUNE can greatly increase its sensitivity to a variety of new physics scenarios by operating in a mode where the proton beam impinges on a beam dump. [...]

SUSY searches in ATLAS and CMS / Matorras Cuevas, Pablo (Cantabria Inst. of Phys.) /ATLAS ,CMS and SUSY Collaborations
A selected summary of the most recent searches for signals of supersymmetry performed at the ATLAS and CMS Collaborations is presented. This presentation was given at the School and Workshops on Elementary Particle Physics and Gravity in Corfu, Greece, and in addition to a brief introduction to supersymmetry and its motivations, a selection of analyses was presented, including searches for gluino/squark, top and bottom squarks, chargino-neutralino pair productions, sleptons, and R-parity violation long lived particles, finishing up with a short conclusion and outlook..
