How Accidental was Inflation? / Antoniadis, Ignatios (Chulalongkorn U. ; Paris, LPTHE) ; Ellis, John (King's Coll. London ; CERN) ; Ke, Wenqi (Minnesota U.) ; Nanopoulos, Dimitri V. (CERN ; Athens Academy ; Texas A-M) ; Olive, Keith A. (Minnesota U.)
Data on the cosmic microwave background (CMB) are discriminating between different models of inflation, disfavoring simple monomial potentials whilst being consistent with models whose predictions resemble those of the Starobinsky $R + R^2$ cosmological model. [...]

SHiP experiment at the SPS Beam Dump Facility / SHiP Collaboration
In 2024, the SHiP experiment, together with the associated Beam Dump Facility (BDF) under the auspices of the High Intensity ECN3 (HI-ECN3) project, was selected for the future physics exploitation of the ECN3 experimental facility at the SPS. [...]

Combination and interpretation of differential Higgs boson production cross sections in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
Precision measurements of Higgs boson differential production cross sections are a key tool to probe the properties of the Higgs boson and test the standard model. [...]
