Degenerate vacua to vacuumless model and $K\bar{K}$ collisions

F. C. Simas, Adalto R. Gomes, K. Z. Nobrega

In this work we investigate a $Z_2$ symmetric model of one scalar field $\varphi$ in $(1,1)$ dimension. The model is characterized by a continuous transition from a potential $V(\varphi )$ with…
