A new cold cooling system using krypton for the future upgrade of the LHC after the long shutdown 4 (LS4) / Contiero, Luca (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Hafner, Armin (Norwegian University of Science and Technology (NTNU) (NO)) ; Banasiak, Krzysztof (Norwegian University of Science and Technology (NTNU) (NO)) ; Allouche, Yosr (Norwegian University of Science and Technology (NTNU) (NO)) ; Petagna, Paolo (CERN)
Future silicon detectors for high-energy physics experiments will require operation at lower temperatures to cope with radiation damage to the sensors and the consequent increase of dark current, beyond the limit of the current CO2 evaporative cooling system. This, along with other requirements such as mass minimization and high radiation hardness, drives the need for new advanced cooling technology. [...]

Study of baryon-strangeness and charge-strangeness correlations in Pb$-$Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV with ALICE / Saha, Swati (Bhubaneswar, NISER ; HBNI, Mumbai)
In the quest to unravel the mysteries of the strong force and the underlying properties of the quark-gluon plasma, the ALICE collaboration at CERN has carried out a comprehensive study focusing on the correlations between net-conserved quantities such as net-baryon, net-charge and net-strangeness.
