چکیده
We argue that the paradoxes associated with infinitely degenerate states, which plague relic particle scenarios for the endpoint of black hole evaporation, may be absent when the relics are horned particles. Most of our arguments are based on simple observations about the classical geometry of extremal dilaton black holes, but at a crucial point we are forced to speculate about classical solutions to string theory in which the infinite coupling singularity of the extremal dilaton solution is shielded by a condensate of massless modes propagating in its infinite horn. We use the nonsingular c = 1 solution of (1+1) dimensional string theory as a crude model for the properties of the condensate. We also present a brief discussion of more general relic scenarios based on large relics of low mass.

Phenomenological and formal restrictions on the evolution of pure into mixed states are discussed. In particular, it is argued that, if energy is conserved, loss of purity is incompatible with the weakest possible form of Lorentz covariance.

We discuss questions arising from the recent work of Schellekens[17], and also from an earlier paper by Schellekens and Yankielowicz[19]. We summarise Schellekens' results, and proceed to discuss the uniqueness of the c = 24 self-dual conformal field theory with no weight one states, i.e. the Monster module V ♮ [8]. After introducing the concept of complementary representations, we examine Z 2-...

We derive an effective local operator produced by certain wormhole instantons in a theory containing a massless Wess-Zumino multiplet coupled to N=1 su-pergravity. The induced interactions are D terms, and hence will not lead to spontaneous supersymmetry breaking. We conclude that supersymmetry suppresses wormhole-induced matter couplings.

A very weakly coupled scalar field with mass m and initial vacuum expectation value V will provide enough mass to close the universe provided V ≃ (3 × 10 8 GeV)(100 GeV/m) 1/4. We discuss possible models in which such a field could arise. (a) Electronic address (internet): [email protected].
