 Search for direct pair production of sleptons and charginos decaying to two leptons and neutralinos with mass splittings near the $W$-boson mass in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector A search for the electroweak production of pairs of charged sleptons or charginos decaying into two-lepton final states with missing transverse momentum is presented.

 Asymptotic Accelerated Expansion in String Theory and the Swampland / Calderón-Infante, José (Madrid, IFT) ; Ruiz, Ignacio (Madrid, IFT) ; Valenzuela, Irene (Madrid, IFT ; CERN) We study whether the universal runaway behaviour of stringy scalar potentials towards infinite field distance limits can produce an accelerated expanding cosmology à la quintessence.

 Beyond the standard model searches in the top quark sectors at ATLAS and CMS / Chatterjee, Suman (Vienna, OAW) /ATLAS and CMS Collaborations Searches for new physics are one of the most active fields of research at LHC. Due to its large mass, the top quark is predicted to have an enhanced coupling with the fields of new physics in several theoretical models. Multiple techniques are developed to probe new physics using the top quark as a tool in different phase space regions. [...] CMS-CR-2022-145.- Geneva : CERN, 2022 - 7 p.

 Upgrade Calorimetry towards high-granularity / Paganis, Efstathios (Taiwan, Natl. Taiwan U.) /CMS Collaboration The increase of the instantaneous luminosity during the High-Luminosity LHC (HL-LHC, phase 2) places stringent requirements on the detectors. New proposed calorimeters have to be designed to operate in the harsh radiation environment at the HL-LHC, where the average number of interactions per bunch crossing is expected to exceed 140.

 Level-1 Triggering on High-Granularity Calorimeter information at the HL-LHC / Portales, Louis (Ecole Polytechnique) /CMS Collaboration The CMS collaboration is building the high granularity calorimeter (HGCAL) for the endcap regions as part of its planned upgrade for the High-Luminosity LHC. The calorimeter data will form part of the Level-1 trigger (hardware) of the CMS experiment, reducing the event rate from the nominal 40 MHz to up to 750 kHz with a decision time (latency) of 10 microseconds.
