The SHiP/NA67 experiment is a general-purpose intensity-frontier experiment for the search for feebly interacting GeV-scale particles and to perform neutrino physics measurements at the HI-ECN3 (high-intensity) beam facility at the CERN SPS, operated in beam-dump mode, taking full advantage of the available $4\times 10^{19}$ protons per year at 400 GeV. The collaboration is currently...
Searches for beyond the Standard Model (BSM) massive long-lived particles decaying to muon pairs face severe irreducible backgrounds in Liquid Argon Time Projection Chambers (LArTPCs). Standard neutrino interactions regularly produce a muon and a pion in the final state, which are currently indistinguishable in LArTPC data. We address this ambiguity using a novel machine-learning method based...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation experiment that will provide new constraints for Beyond Standard Model (BSM) phenomena. Lorentz invariance is one of the fundamental principles of quantum field theory and is closely related to symmetries such as charge, parity, and time (CPT) reversal, which form the foundation of the Standard Model (SM)...
We propose a unified representation-theoretic reinterpretation of electroweak decay phenomenology based on tachyonic wavefunctions derived in a recent group theoretic extension of special relativity to include superluminal objects. The starting point is the extended space-time geometry in which the invariant content of a four vector is not $\Delta s^2$, but its modulus $|\Delta s^2|$....
