In this paper we define and study the ghost loop orbifold L s X of an orbifold X consisting of those loops that remain constant in the coarse moduli space of X. We construct a configuration space model for L s X using an idea of G. Segal. From this we exhibit the relation between the Hochschild and cyclic homologies of the inertia orbifold of X (that generate the so-called twisted sectors in string theory) and the ordinary and equivariant homologies of L s X. We also show how this clarifies thedoi:10.1093/qmath/hag053 fatcat:rxmvyzzlnnaedhzpevzgppsncm
