DESCRIPTION:Speakers: S. T. Petcov (INFN/SISSA\, Trieste\, Italy\, Kavli I
 PMU\, University of Tokyo\, Japan)\n\nAbstractAspects of High-Scale and Lo
 w-Scale leptogenesis theory will be discussed. After summarising the curr
 ent status of neutrino physics and the principal goals of the future resea
 rch in this field\, we will consider the type I seesaw mechanism of neutri
 no mass generation on which leptogenesis is based and comment on the possi
 ble origins of CP-violation in leptogenesis. An integral part of the type 
 I seesaw mechanism and leptogenesis are the heavy Majorana neutrinos\, who
 se masses determine the scale of leptogenesis\; their phenomenology will b
 e briefly outlined.The theory of high-scale leptogenesis will be reviewed 
 and examples of results of successful generation of the baryon asymmetry o
 f the Universe (BAU) will be given. It will be shown that it is possible t
 o reproduce the observed value of BAU even in the case when the CP-violati
 on is provided in leptogenesis exclusively by the Dirac or/and Majorana CP
 -violation phases present in PMNS neutrino mixing matrix. We will comment 
 on the compatibility of high-scale leptogenesis with the so-called "Neutri
 no Option" scenario. Low-scale leptogenesis and the possibilities to test 
 it experimentally will be also briefly reviewed.BiographyProf. Petcov comp
 leted his PhD at Laboratory of Theoretical Physics\, JINR\, Dubna\, USSR\,
  in 1977 and became a Professor at SISSA\, Trieste\, Italy\, in 1994. Prof
 . Petcov has made notable contributions in the fields of neutrino\, partic
 le and astrophysicle physics (such as the Vector Boson Fusion (VBF) mechan
 ism of Higgs boson production (1979)\; the existence of  Majorana CP-vio
 lating phases in the lepton mixing matrix (1980)\; the novel method of neu
 trino mass ordering determination using reactor neutrinos\, on which the J
 UNO experiment is based (2001)\; a novel mechanism of resonance-like enhan
 cement of the Extra open brace or missing close bracetransitions of neutr
 inos crossing the Earth core (NOLR\, 1998))\, used in neutrino tomography 
 of the Earth). Prof. Petcov has won the Pontecorvo Prize for the year 201
 0 for fundamental contribution to the investigation of neutrino propagatio
 n in matter\, μ→e+γ\, μ→3e processes and Majorana properties of 
 neutrinos (that is awarded by the Joint Institute of Nuclear Research\, Du
 bna\, Russia). \n\nhttps://indico-tdli.sjtu.edu.cn/event/2638/
