Moduli space of paired punctures, cyclohedra and particle pairs on a circle

Abstract In this paper, we study a new moduli space ℳ n + 1 c $$ {\mathrm{\mathcal{M}}}_{n+1}^{\mathrm{c}} $$ , which is obtained from ℳ 0 , 2 n + 2 $$ {\mathrm{\mathcal{M}}}_{0,2n+2} $$ by identifying pairs of punctures. We find that this space is tiled by 2 n − 1 n! cyclohedra, and construct the c...
