DESCRIPTION:Speakers: Fedor Martynenko (Samara University)\nThe cross sect
 ions for the production of single and paired dileptons in electron-positro
 n annihilation are calculated within the framework of quantum electrodynam
 ics. Both one-photon and two-photon mechanisms of electron-positron annihi
 lation with subsequent production of leptons are considered. The formation
  of both singlet and triplet states of dimuonium and ditauonium is studied
 . The production cross sections are constructed taking into account relati
 vistic corrections in the production amplitude and the wave function of th
 e bound state\, as well as the binding energy of leptons in the bound stat
 e.\n\nhttps://indico.particle.mephi.ru/event/436/contributions/4300/
