Latest neutrino results from the FASER experiment and their implications for forward hadron production Open
The muon puzzle -- an excess of muons relative to simulation predictions in ultra-high-energy cosmic-ray air showers -- has been reported by many experiments. This suggests that forward particle production in hadronic interactions is not f…

First Measurement of the Muon Neutrino Interaction Cross Section and Flux as a Function of Energy at the LHC with FASER Open
This Letter presents the measurement of the energy-dependent neutrino-nucleon cross section in tungsten and the differential flux of muon neutrinos and antineutrinos. The analysis is performed using proton-proton collision data at a center…

Shining light on the dark sector: search for axion-like particles and other new physics in photonic final states with FASER Open
A bstract The first FASER search for a light, long-lived particle decaying into a pair of photons is reported. The search uses LHC proton-proton collision data at $$ \sqrt{s} $$ = 13 . 6 TeV collected in 2022 and 2023, corresponding to …

Shining Light on the Dark Sector: Search for Axion-like Particles and Other New Physics in Photonic Final States with FASER Open
The first FASER search for a light, long-lived particle decaying into a pair of photons is reported. The search uses LHC proton-proton collision data at $\sqrt{s}=13.6~\text{TeV}$ collected in 2022 and 2023, corresponding to an integrated …

Neutrino rate predictions for FASER Open
The Forward Search Experiment (FASER) at CERN’s Large Hadron Collider (LHC) has recently directly detected the first collider neutrinos. Neutrinos play an important role in all FASER analyses, either as signal or background, and it is ther…

Boosted object identification in searches in ATLAS and CMS Open
Reconstruction and identification of objects with high transverse momentum (p$_{\\mathrm{T}}$), like top quarks and W, Z, Higgs bosons, from their hadronic decays can play a significant role in both searches for new physics and measurement…

The Level-1 CMS electron and photon trigger for the LHC Run II Open
The CMS experiment implements a sophisticated two-level triggering system composed of the Level-1, instrumented by custom-design hardware boards, and a software High Level Trigger. A new Level-1 trigger architecture with improved performan…
