Electromagnetic Shower Reconstruction and Identification in FASER's Emulsion Detector for LHC Forward Neutrino Measurements
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +132
We present methods for electromagnetic shower reconstruction and identification in the FASERnu emulsion detector using 100 GeV and 200 GeV electron test-beam data from the CERN SPS…
Momentum Measurement of Charged Particles in FASER's Emulsion Detector at the LHC
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +132
We present a momentum measurement method based on multiple Coulomb scattering (MCS) in the FASER emulsion detector. The measurement of charged-particle momenta is essential for…
The X17 with Chiral Couplings
Max H. Fieg, Toni Mäkelä, Tim M. P. Tait +1
In recent years, the ATOMKI collaboration has performed a series of measurements of excited nuclei, observing a resonant excess of electron-positron pairs at large opening angles c…
First Measurement of the Muon Neutrino Interaction Cross Section and Flux as a Function of Energy at the LHC with FASER
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +107
This letter presents the measurement of the energy-dependent neutrino-nucleon cross section in tungsten and the differential flux of muon neutrinos and anti-neutrinos. The analysis…
Discovering neutrino tridents at the Large Hadron Collider
Wolfgang Altmannshofer, Toni Mäkelä, Subir Sarkar +3
Neutrino trident production of di-lepton pairs is well recognized as a sensitive probe of both electroweak physics and physics beyond the Standard Model. Although a rare process, i…
