Abstract: Neutrino Oscillations have been firmly established by experiments conducted in the last two decades with solar, atmospheric, accelerator and reactor neutrinos leading to the determination of the neutrino mass-eigenvalue differences (squared) and of the three angles of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. Outstanding issues are still to be settled, namely, the possible existence of CP violation in the leptonic sector and the hierarchy of the neutrino mass eigenvalues. In addition, some anomalies seem to give hints for a required extension of the minimal PMNS oscillation scheme by invoking the existence of still undetected sterile neutrinos. The Liquid Argon Time Projection Chamber (LAr-TPC) is a prime candidate detector for future neutrino oscillation experiments, large-mass neutrino observatories and proton decay searches. In this talk, I will present the ArgonCube collaboration which submitted a letter of intend to CERN SPSC to propose a novel LAr-TPC technology based on a fully-modular and innovative design. A large LAr-TPC detector will be installed and operated at the future Neutrino Platform facility at CERN for a complete engineering and physics test program also employing charged particle beams for a fully study of the detection performance. I will also mention about A Short-Baseline Neutrino (SBN) physics program of three LAr-TPC detectors located along the Booster Neutrino Beam (BNM) at Fermilab. This new SBN Program will deliver a rich and compelling physics opportunity, including the ability to resolve a class of experimental anomalies in neutrino physics and to perform the most sensitive search to date for sterile neutrinos at the eV mass-scale through both appearance and disappearance oscillation channels.

Reminder: Tea and cookies will be in the seminar room before the seminar.
