概要
- 論文の詳細を見る
It is shown that the one-loop two-point amplitude in Lorentz-invariant non-commutative (NC)φ^3 theory is finite after subtraction in the commutative limit and satisfies the usual cutting rule. This eliminates the unitarity problem in Lorentz-non-invariant NC field theory in the approximation considered.
