摘要：
We have studied CPT Violation in atmospheric neutrino oscillation considering two flavour framework with matter effects. We analyze the atmospheric neutrino data within the simplest scheme of two neutrino oscillation. We consider as special case of matter density profile, which are relevant for neutrino oscillations. In particular, we compute to constrain a specific from of CPT violation in matter by upper bound, vertical bar Delta(m)(31) - <(Delta(m)(31))over bar> << 4.80 x 10(-3) eV(2) and vertical bar sin2 theta(m)(13) - sin2 theta<((m)(13))over bar>vertical bar < 0.685. The dispersion relation for the CPT violation in neutrino oscillation in matter are discussed
