$$\varLambda (1405)$$ Λ ( 1405 ) mediated triangle singularity in the $$K^-d\rightarrow p\varSigma ^-$$ K - d → p Σ - reaction
Abstract We study for the first time the $$p\varSigma ^-\rightarrow K^-d$$ p Σ - → K - d and $$K^-d\rightarrow p\varSigma ^-$$ K - d → p Σ - reactions close to threshold and show that they are driven by a triangle mechanism, with the $$\varLambda (1405)$$ Λ ( 1405 ) , a proton and a neutron as inter...
