Process Quality Control Strategy for the Phase-2 Upgrade of the CMS Outer Tracker and High Granularity Calorimeter / Hinger, Viktoria
Between 2025 and 2027, some essential components of the CMS (Compact Muon Solenoid) detector - most notably the tracker and the calorimeter endcap - will be upgraded to prepare for HL-LHC (High Luminosity Large Hadron Collider) conditions. [...]

Triggering long-lived particles in HL-LHC and the challenges in the first stage of the trigger system / Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Mukherjee, Swagata (Aachen, Tech. Hochsch.) ; Sengupta, Rhitaja (Bangalore, Indian Inst. Sci.) ; Solanki, Prabhat (Bangalore, Indian Inst. Sci.)
Triggering long-lived particles at the first stage of the trigger system is very crucial in LLP searches to ensure that we do not miss them at the very beginning. [...]

Measurements of the production cross-section for a $Z$ boson in association with $b$-jets in proton$-$proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
This paper presents a measurement of the production cross-section of a $Z$ boson in association with $b$-jets, in proton$-$proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 35.6 fb$^{-1}$. [...]
