    “…A search for the radiative decay of excited leptons, $\ls$ and $\ns$, and for the weak decay of excited electron neutrinos, $\ns_e$, was undertaken using the $21.8\ipb$ of data collected by ALEPH at 161--$172\gev$, No evidence for a signal was found in single or pair production. …”

    Publicado 2002
    “…In this letter we give a class of examples where the decays of the heavy Majorana neutrinos may violate CP even if there is no CP violation at low energies, i. e., leptogenesis can take place without Majorana or Dirac type CP phases at low energies.…”

    Publicado 1993
    “…Upon using the same theoretical framework, I describe two interesting decay processes: the electromagnetic plasmon decay into neutrinos, which can be the dominant cooling mechanism for red giants and white dwarfs, and the gluonic plasmon decay into quarks, which can be measured in ultra-relativistic heavy-ion collisions.…”
