Doubly Charged Fermions Bound States,Vector Bosons Bound States

Abstract

We consider positronium-like bound states of doubly charged fermions.We consider also $P(CP)$-parity violation in positronium like system (including quarkonium and lepton antilepton bound states and mesoatoms) which take place due to $Z^0$-bosons or Higgs bosons exchange.By model independent way we consider also vector bosons bound states in the Coulomb and Higgs potential and have shown that in the presence of the Higgs potential effective potential become less singular and in this case fall down on the center is absent.Vector bosons energy levels in the magnetic field are considered. Considered magnetism of electron gas in the finite volume.
