講演タイトル title：
Lorentz invariant CPT violation: Particle and antiparticle mass
splitting
講演アブストラクト abstract：
The interpretation of neutrino oscillation data has led to the
question whether, in principle, an antiparticle like antineutrino
can have a different mass than its particle. In the framework of
a Lorentz invariant CPT violation, which is based on the nonlocal
interaction vertex and characterized by the infrared divergent
form factor, we present an explicit Lagrangian model for the
fermion and antifermion mass splitting.
