We present a measurement of electron-neutrino interactions from the Fermilab Booster Neutrino Beam using the MicroBooNE liquid argon time projection chamber to address the nature of the excess of low-energy interactions observed by the MiniBooNE collaboration. Three independent electron-neutrino searches are performed across multiple single-electron final states, including an exclusive search for two-body scattering events... More »

The European Strategy in Particle Physics, has put an e+e- factory as first priority and recommended that Europe, together with its international partners, should investigate the technical and financial feasibility of a future hadron collider at CERN with a centre-of-mass energy of at least 100 TeV, and with an electron-positron Higgs and electroweak factory as...

Enabling new long-lived particles (LLPs) searches at the LHC presents HEP research with unique opportunities. Introducing novel experimental techniques to identify and reconstruct LLPs will open up new possibilities for discoveries with striking signatures. I will present new  long-lived particles searches, with a focus on the CMS Muon System result, which significantly pushed the envelope... More »

Current and next generation precision neutrino oscillation experiments aim to probe CP-violation in the lepton sector, the neutrino mass ordering, and physics beyond the Standard Model such as the existence of light sterile neutrinos by measuring the appearance of electron neutrinos in nearly pure beams of muon neutrinos. Yet to this day, only a handful of...

The MicroBooNE liquid argon time projection chamber (LArTPC) has collected a record number of neutrino interactions from two high-intensity neutrino beamlines (BNB and NuMI) at Fermilab. The experiment has demonstrated that liquid-argon technology enables a far-reaching physics program, and has recently released its first results investigating the nature of the MiniBooNE anomalous excess of low-energy...
