        Seminar

        Title: Is the active sub-eV neutrino Dirac or Majorana?
        Speaker: Prof. Choong Sun Kim, (Yonsei University)
        Time: Friday, July 15, 2022, 3:00 pm (Beijing Time)
        ZOOM: 85951392529 / 553576

        Abstract: The nature of neutrino, whether it is a Dirac type or Majorana type, may be comprehensively probed using their quantum statistical properties. If neutrino is a Majorana fermion, then by definition it is identical and indistinguishable from the corresponding antineutrino. When a Majorana neutrino and antineutrino are pair produced, the corresponding state has to obey Pauli principle unlike in the Dirac case. We use this property to distinguish between the two cases using the process B0 → μ? μ+ νμ ˉνμ. I also give comments on possible use of J/psi -> mu mu nu nu, which can be directly probed at BES III.

        About the Speaker: C.S.Kim (Choong Sun Kim,金忠善) 教授1988年博士畢業于美國威斯康星大學麥迪遜分校(University of Wisconsin-Madison),1988-1991年在英國杜倫大學 (University of Durham)做博士后,1992年至今任職韓國延世大學 (Yonsei University)。研究方向主要集中于粒子物理唯象學,包括對撞機物理,CP破壞,重味物理,超出標準模型的新物理唯象學等。
