Spectroscopy of Strange Mesons and First Observation of a Strange Crypto-Exotic State with $J^P=0^-$ / COMPASS Collaboration
We measured the strange-meson spectrum in the scattering reaction $K^{-}+p \rightarrow K^{-}\pi^{-}\pi^{-}+p$ with the COMPASS spectrometer at CERN. [...]

Reinterpretation and preservation of data and analyses in HEP / LHC Reinterpretation Forum Collaboration
Data from particle physics experiments are unique and are often the result of a very large investment of resources. [...]

Measurement of the hard exclusive $\pi^{0}$ muoproduction cross section at COMPASS / COMPASS Collaboration
A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality $Q^2$ ranging from 1 to 8 (GeV/$c$)$^{\rm\, 2}$ and the Bjorken variable $x_{\rm Bj}$ ranging from 0.02 to 0.45. [...]

Multiplicities of positive and negative pions, kaons, and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target / COMPASS Collaboration
The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable $x$, the relative virtual-photon energy $y$ and the fraction of the virtual-photon energy transferred to the final-state hadron $z$. Data were obtained by the COMPASS Collaboration using a 160 GeV muon beam of both electric charges and a liquid hydrogen target. [...]

Black Holes from Supercharge Cohomology / Chang, Chi-Ming (speaker)
In this talk, I will introduce supercharge cohomology, which is semi-protected by supersymmetry and reveals much richer information beyond state counting. I will classify supercharge cohomologies in holographic conformal field theories into two categories: monotone (graviton) and fortuitous (black hole). [...]

High-Statistics Measurement of Collins and Sivers Asymmetries for Transversely Polarized Deuterons / COMPASS Collaboration
New results are presented on a high-statistics measurement of Collins and Sivers asymmetries of charged hadrons produced in deep inelastic scattering of muons on a transversely polarised $^6$LiD target. The data were taken in 2022 with the COMPASS spectrometer using the 160 \gevv muon beam at CERN, balancing the existing data on transversely polarised proton targets. [...]

Final COMPASS results on the transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan process / COMPASS Collaboration
The COMPASS Collaboration performed measurements of the Drell-Yan process in 2015 and 2018 using a 190 GeV/c $\pi^{-}$ beam impinging on a transversely polarised ammonia target. Combining the data of both years, we present final results on the amplitudes of the five azimuthal modulations in the dimuon production cross section. [...]

Measurement of the inclusive semileptonic $B$ meson branching fraction in 62.8 fb$^{-1}$ of Belle II data / Belle-II Collaboration
We report a measurement of the branching fraction of inclusive semileptonic $B$ meson decays $B\to X_c\ell\nu\ell$ in $\Upsilon(4S)\to B\bar B$~data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider and corresponding to 62.8 fb$^{-1}$ of integrated luminosity.

Collider constraints on electroweakinos in the presence of a light gravitino / GAMBIT Collaboration
Using the GAMBIT global fitting framework, we constrain the MSSM with an eV-scale gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos and charginos) as the only other light new states. We combine 15 ATLAS and 12 CMS searches at 13 TeV, along with a large collection of ATLAS and CMS measurements of Standard Model signatures. [...]
