A PARTICULAR THIN-SHELL WORMHOLE

Using a black hole with scalar hair, we construct a scalar thin-shell wormhole (TSW) in 2+1 dimensions by applying the Visser cut and paste technique. The surface stress, which is concentrated at the wormhole throat, is determined using the Darmois-Israel formalism. Using various gas models, we analyze the stability of the TSW. The stability region is changed by tuning the parameters l and u. We note that the obtained TSW originating from a black hole with scalar hair could be more stable with a particular value of the parameter l, but it still requires exotic matter.
