Effective Theory Approach to the Skyrme model and Application to Pentaquarks

Koji Harada, Yohei Mitsunari, Nao-aki Yamashita

The Skyrme model is reconsidered from an effective theory point of view. From the most general chiral Lagrangian up to including terms of order $p^4$, $N_c$ and $\delta m^2$ ($δm\equiv m…
