Federico Sanchez





I am an experimental physicist specialised in neutrino physics and detector technology. I graduated at the Univ. of Sevilla and I got my PhD at the Universitat Autònoma de Barcelona working at an experiment at CERN (Switzerland). I worked as researcher at the Deutsches Elektronen Synchroton (DESY) in Hamburg (Germany) developing a couple trigger system for the HERA-B experiment and at the Max Planck Institute fur Kernphysik in Heidelberg where I acted as co-physics coordinator of the HERA-B experiment. I have worked at several particle physics experiments like ALEPH at CERN or HERA-B at DESY. In 2002, I joined the K2K experiment in Japan and since then I am working on neutrino physics as the leader of the group at IFAE. I participate in the T2K experiment in Japan from almost the very beginning. In T2K, I made major contributions to the experiment construction and main results, mainly the first explicit appearance result in neutrino oscillations. I was awarded with the Breakthrough prize on fundamental physics in 2016, together with the K2K and T2K collaborations for the discovery of neutrino oscillations. Between 2007 and 2011, I was member of the Nemo and SuperNemo collaborations and contributed to the preliminary ideas of the NEXT experiment searching for double beta decay without neutrinos. In August 2018, I moved as professor at the Université of Genève where I direct the group dedicated to neutrino physics at the T2K and HK experiments.  I have been involved in the development of the theory of neutrino-nucleus cross-sections with the goal to reduce the systematics of the neutrino oscillation experiments.  The contributions vary from phenomenology developments to event generators, but also data analysis and model comparison. I am member of the Neutrino Scattering Theory Experiment Collaboration (NusTEC) executive committee from its foundation. I have been also interested in the development of detectors, both based on gas detectors such as Time Projection Chambers and scintillator based trackers readout with MPPC’s with the aim at low and moderate energy neutrino experiments. In April 2018 I was elected International Cospokeperson of the T2K collaboration. 



Neutrino Oscillations & Cross-Sections


The DPNC neutrino group is involved in two aspects of the neutrino physics.  The group is contributing to the neutrino oscillation experiment T2K in Japan. The contributions of the DPNC group to the T2K experiment focus on several aspects of the near detector:

  • Analysis of the near detector data to reduce the systematic errors associated to the uncertainties in the cross-section of neutrinos with nuclei. 
  • Development of neutrino interaction models and the inclusion on event generators used for extracting physics measurements from the experiment. 
  • Development of new bayesian statistical methods based on Deep Learning to improve complex data fits with many free parameters as needed by multiparameter fit of oscillation physics. 



Detector research and development   


The group has been involved in different detector development concepts related to neutrino and low energy physics : 

  • Construction and operation of the ND280 detector. The group has responsibilities in the operation of the large TPC detectors and the magnet.  
  • Construction and operation of the Wagasci-BabyMind detector. The group developed the BabyMind detector in collaboration with CERN. The detector was shipped to Japan in 2018 and it is being commissioned. 
  • Development of the new generation of neutrino detectors based on highly granulated quasi-3D fine grained scintillator target tracker.
  • Development of  new concepts of optical TPC's.
