New dimensions at a millimeter to a Fermi and superstrings at a TeV
Abstract Recently, a new framework for solving the hierarchy problem has been proposed which does not rely on low energy supersymmetry or technicolor. The gravitational and gauge interactions uniteExpand

On the cosmological constant problem
Abstract We prove that Weyl invariant theories of gravity possess a remarkable property which, under very general assumptions, explains the stability of flat space-time. We show explicitly howExpand

Topological amplitudes in string theory
We show that certain type II string amplitudes at genus g are given by the topological partition function Fg discussed recently by Bershadsky, Cecotti, Ooguri and Vafa. These amplitudes give rise toExpand

Journal of High Energy Physics Little string theory at a TeV
We propose a framework where the string scale as well as all compact dimensions are at the electroweak scale ∼ TeV−1. The weakness of gravity is attributed to the small value of the string couplingExpand

Aspects of type I– type II– heterotic triality in four dimensions
We discuss the equivalence between Type I, Type II and Heterotic N = 2 superstring theories in four dimensions. We study the effective field theory of Type I models obtained by orientifold reductionsExpand

String loop corrections to the universal hypermultiplet
We study loop corrections to the universal dilaton supermultiplet for type IIA strings compactified on Calabi-Yau threefolds. We show that the corresponding quaternionic kinetic terms receiveExpand

R4 couplings in M- and type II theories on Calabi-Yau spaces
Abstract We discuss several implications of R4 couplings in M-theory when compactified on Calabi-Yau (CY) manifolds. In particular, these couplings can be predicted by supersymmetry from the mixedExpand

A Possible new dimension at a few TeV
We examine the possibility of the existence of a large internal dimension at relatively low energies of the order of a few TeV. Such a dimension is a general prediction of perturbative stringExpand

Spontaneous breaking of N = 2 global supersymmetry
Abstract We study spontaneous supersymmetry breaking in N = 2 globally supersymmetric theories describing a system of abelian vector multiplets. We find that the most general form of the actionExpand

N = 2 heterotic superstring and its dual theory in five dimensions
Abstract We study quantum effects in five dimensions in heterotic superstring theory compactified on K 3 × S 1 and analyze the conjecture that its dual effective theory is eleven-dimensionalExpand
