Witryna4 lut 2013 · Similarly, γ 5-hermiticity is commonly used as an Hermite condition, but we cannot forbid non-Hermite or complex couplings directly. A kinetic term that reduces the number of doublers allows the possibility of generating these anti-Hermite effective coupling constants. R-hermiticity is a criterion to remove non-hermiticity. 3.
