The Cutkosky rule of three dimensional noncommutative field
... • We have checked the Cutkosky rule of the one-loop self-energy amplitudes in the noncommutative theory with the braiding. • As a result, this theory will not be unitary even when we impose the braiding. • This is caused by the periodic property of the SL(2,R)/Z_2 group momentum space. ...
