🧐 A New Way to See Electron Neutrinos at the LHC 🔍 Measurement of electron neutrinos using the calorimeter, a subdetector that captures a particle’s energy. These exciting results demonstrate yet another way that we can measure high-energy neutrinos! faser.web.cern.ch/briefing-2…

Photographing TeV Neutrinos with FASER 📸 Measuring neutrino interaction cross sections in a previously unexplored energy range using the FASERν emulsion detector. Extends beyond current artificial neutrino sources and approaches energy scales of cosmic sources.

Einem Team mit Beteiligung der #unibern hat Neutrino-Wechselwirkungen bei Teilchenkollisionen im #LHC des @CERN bei bisher unerreichten Energien gemessen. Diese #Neutrinos könnten erste Spuren bisher ‘unentdeckter Physik’ sein: sohub.io/nen3. @FASERexperiment @BernLhep

A team involving #unibern has measured neutrino interactions in particle collisions in the #LHC of @CERN at unprecedented energies. The high-energy #neutrinos could be the first traces of previously 'undiscovered physics': sohub.io/a0hg. @FASERexperiment @BernLhep

The strength of a neutrino 💪 Recently, the @FASERexperiment at CERN measured high-energy neutrino interaction strength. At the annual @_Moriond_ conference, the FASER collaboration presented a measurement of the interaction strength of electron neutrinos (νe) and muon neutrinos (νμ). The energies of the neutrinos were found to be in a range between 500 and 1700 GeV. The interaction strength of neutrinos had never previously been measured in this energy range.

🚨 More data incoming! 🚨 First stable beams collisions of the year! Looking forward to what we can do with this new data in the coming months. #BeamTime #LHCRun3
5 Apr 2024
Today, the LHC receives the first stable beams of 2024 – a few short weeks after the first #BeamTime of the year and after several weeks of getting the #LHC ready for chapter three of #LHCRun3. While we appreciate the excitement for the solar eclipse next Monday, CERN’s accelerator complex moves on a different schedule than the geometry of the Universe.😉 Find out more: home.cern/news/news/accelera…

We make our first electron and muon neutrino cross section measurements using our emulsion detector. These are also the first neutrino cross section measurements at TeV energy scales! 🥳 arxiv.org/abs/2403.12520

We also presented our first search for axion-like particles (ALPs)! These could explain the strong CP problem. Unfortunately we see no sign of these new particles, but can set exclusion limits in new regions of parameter space.
