A search for dark matter produced in association with a dark Higgs boson decaying into a Higgs boson pair in 3$b$ or 4$b$ final states using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
A search is performed for dark matter particles produced in association with a resonant pair of Higgs bosons using 140 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. [...]

Search for decays of the Higgs boson into scalar particles decaying into four or six $b$-quarks using $pp$ collisions at $\sqrt{s}= 13\,\mathrm{TeV}$ with the ATLAS detector
A search for exotic decays of the Higgs boson $H$ into new scalar or pseudoscalar particles that subsequently decay into $b$-quarks is presented [...]

Constraining primordial curvature perturbations with present and future GW detectors / Pieroni, Mauro (Madrid, Inst. Estructura Materia ; CERN)
Primordial scalar curvature perturbations ($\zeta$), typically probed on large cosmological scales via CMB and LSS observations, can be significantly enhanced on smaller scales by various early Universe mechanisms, for instance, non-minimal inflationary models. [...]

Operation of the Trigger System for the ICARUS Detector at Fermilab / ICARUS Collaboration
The ICARUS liquid argon TPC detector is taking data on the Booster (BNB) and Main Injector (NuMI) Neutrino beam lines at Fermilab with a trigger system based on the scintillation light produced by charged particles in coincidence with the proton beam extraction from the accelerators. [...]

Search for squarks and gluinos in $pp$ collisions at $\sqrt{s} = 13$ TeV and $13.6$ TeV in events with $\tau$-leptons, jets and missing transverse momentum using the ATLAS detector
A search for R-parity-conserving supersymmetry in events with large missing transverse momentum, jets and at least one hadronically decaying $\tau$-lepton is presented. [...]

Extreme Blazars Observed with MAGIC: Second Catalog Release / Foffano, Luca (CERN) /RE23/CTA-LST Collaboration
Extremely high-peaked BL Lac objects - also named extreme blazars - are among the most energetic and persistent extragalactic accelerators in the Universe. These sources are defined by a synchrotron emission peaking above 1017 Hz (∼ 0.3 keV) in the X-ray band [...]

Search for the nonresonant and resonant production of a Higgs boson in association with an additional scalar boson in the $ \gamma\gamma\tau\tau $ final state in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
The results of a search for the production of two scalar bosons in final states with two photons and two tau leptons are presented. [...]

Probing Neutral Triple Gauge Couplings via $ZZ$ Production at $e^+e^-$ Colliders / Ellis, John (Shanghai Jiao Tong U. ; King's Coll. London ; CERN) ; He, Hong-Jian (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Tsinghua U., Beijing ; Peking U., CHEP) ; Xiao, Rui-Qing (Peking U.) ; Zeng, Shi-Ping (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U.)
Neutral triple gauge couplings (nTGCs) first arise from the dimension-8 operators of the Standard Model Effective Field Theory (SMEFT), rather than the dimension-4 SM Lagrangian and dimension-6 SMEFT operators, opening up a unique window for probing new physics at the dimension-8 level. [...]
