论文摘要
我们基于乳头,核子,三角洲和roper共振的两种味道有效的拉格朗日的有效拉格朗日,计算与roper共振相对应的能级。我们表明,可以从这些水平中提取roper质量,而不是太大的晶格量。
We calculate the energy levels corresponding to the Roper resonance based on a two-flavor chiral effective Lagrangian for pions, nucleons, deltas and the Roper resonance at leading one-loop order. We show that the Roper mass can be extracted from these levels for not too large lattice volumes.
