DESCRIPTION:Speakers: Masahiro Yoshimoto (Gifu University)\nThe production
  process of tau neutrinos is\, up-to-date\, largely unknown compared with 
 other neutrino flavors. The NA65 (DsTau) experiment is an approved CERN ex
 periment with the scope to investigate the tau neutrino production using a
 n emulsion cloud chamber (ECC).\n\nThe main production process of tau neut
 rinos is the sequential decay of Ds mesons produced by the reaction of the
  high-energy protons and nucleons. The tau neutrinos are emitted both when
  the Ds mesons decay into tau leptons and when the tau leptons decay to ot
 her particles. The NA65 experiment aims to measure the differential produc
 tion cross section of the Ds mesons emerging from the 400 GeV/c proton bea
 m interaction with the metal plates.\n\nThe NA65 emulsions are read out in
  a whole area because the sequential decay cannot be detected by other ele
 ctronic trackers. We use an automated track-readout system HTS which is tw
 o orders of magnitude faster than the one used in the previous neutrino ex
 periment OPERA. It is also a challenge to reconstruct the massive amount o
 f track data\, which reaches 5×105 tracks/cm2 at the downstream part of E
 CC.\n\nIn this presentation\, we present an overview of the NA65 (DsTau) e
 xperiment\, the interim results of the 2018 pilot run\, and the plans for 
 the 2021 physics run.\n\nhttps://indico.particle.mephi.ru/event/35/contrib
