TL;DR: A section of the UA1 uranium/tetramethylpentane forward calorimeter has been tested with muon and electron beams from the CERN Super Proton Synchrotron as mentioned in this paper.

TL;DR: In this article, a new method to account for these additional interactions in the simulation chain is described, instead of sampling the inelastic interactions and adding their energy deposits to a hard-scatter interaction one-by-one, the interactions are presampled, independent of the hard scatter, and stored as combined events.

TL;DR: In this paper , a statistical combination of searches for H $\rightarrow$ invisible decays where multiple production modes of the Standard Model Higgs boson are considered was performed with the ATLAS detector using 139 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 13$ TeV at the LHC.

TL;DR: In this article, the authors measured the branching ratio of φ mesons with the KLOE detector using a sample of ∼5×10 7 φ decays and fit the two-pion mass spectrum to models to disentangle contributions from various sources.

TL;DR: In this paper, the main goal of the KLOE experiment is the study of CP violation in the K mesons system, with an accuracy of 10−4 in the measurement of Re( e′ e ).
