EOS at IHEP / li, Haibo (speaker) (Institute of High Energy Physics Chinese Academy of Science)
In this presentation, we will report our current experiences and challenges with running EOS instances for used by IHEP CAS. Currently, IHEP has a total of 42PB storage, of which EOS accounts for 16PB, an increase of 10PB in 2020. [...]

The first disk-based custodial storage for the ALICE experiment / Ahn, Sang Un (speaker) (Korea Institute of Science & Technology Information (KR))
We present a disk-based custodial storage for the ALICE experiment at CERN to preserve its raw data alternative to tape with the EOS QRAIN. In this presentation, we describe the detailed system deployment of disk-based custodial storage, the integration to the ALICE experiment and the current status of system monitoring such as hardware error detection and power consumption measurement..

ALICE shines light inside the proton and nuclei / Broz, Michal (speaker) (Czech Technical University in Prague (CZ))
The strong electromagnetic fields generated by ultrarelativistic heavy ions provide the possibility to study photon-induced interactions at the LHC in new kinematic regions. Vector mesons are copiously produced in ultra-peripheral collisions where the impact parameter is larger than the sum of the radii of the two projectiles, implying that electromagnetic induced processes become dominant [...]

Illuminating Antimatter: the ALPHA antihydrogen experiment at CERN / Hangst, Jeffrey Scott (speaker) (Aarhus University (DK))
The ALPHA experiment at the Antiproton Decelerator is unique in its combined ability to produce, trap, and study atoms of antihydrogen - the simplest anti-atom. The Standard Model requires that hydrogen and antihydrogen have the same spectrum [...]

Towards GAMBIT 2.0 / Kvellestad, Anders (speaker) (University of Oslo)
The Global and Modular Beyond-the-standard-model Inference Tool (GAMBIT) is an open-source framework for performing BSM global fits. In this talk I will give update on recent and ongoing developments in GAMBIT. [...]

Constraining Electroweakinos in the Minimal Dirac Gaugino Model / Reyes-González, Humberto (speaker) (University of Genoa)
Supersymmetric models with Dirac gauginos, instead of Majorana, are known to have distinctive phenomenological properties. Concretely, in the Minimal Dirac Gaugino Supersymmetric Standard Model (MDGSSM) the electroweakino sector is characterized by an enriched spectrum with a total of 6 neutralinos and 4 charginos exhibiting naturally small mass splittings and thus, yielding a frequent presence of scenarios with Long Lived Particles (LLPs). In this talk, we explore the electroweakino sector of the MDGSSM on the light of dark matter (DM) and collider constraints. [...]

Direct Detection of Dark Matter: Precision Predictions in a Simplified Model Framework / Borschensky, Christoph (speaker) (University of Tübingen)
We present a calculation of the next-to-leading order QCD corrections for the scattering of Dark Matter particles off nucleons in the framework of simplified models with $s$- and $t$-channel mediators. These results are matched to the Wilson coefficients and operators of an effective field theory that is generally used for the presentation of experimental results on spin-independent and spin-dependent direct detection rates. Detailed phenomenological studies illustrate the complementary reach of collider searches for Dark Matter and the direct detection experiments CRESST and XENON. [...]

EWino searches in CheckMate and $(g-2)_\mu$ in the MSSM / Chakraborti, Manimala (speaker)
We implemented (and validated) the most recent searches for EWinos in the MSSM into CheckMate. These newly included search results are crucial for the interpretation of the anomalous magnetic moment of the muon. [...]

Exploring Multilepton Signatures From Dark Matter at the LHC / Freegard, Arran Charles (speaker) (Queen Mary University of London (GB))
While overwhelming cosmological evidences point to the existence of Dark Matter (DM), only its gravitational interaction has been experimentally confirmed. Limitations on the most general mono-X DM signature at colliders motivate searches beyond this. [...]
