CP violation and target-space modular invariance
We show that, in perturbative string models where the source of CP violation is a complex vacuum expectation value (v.e.v.) for one or more compactification moduli, CP is conserved if a CP transformation acting on the modulus values is an element of a target-space (self-)duality group. Where the duality group is SL(2, Z) the result confirms a conjecture of Bailin et al. that CP is conserved for...
متن کاملModular-invariance of trace functions in orbifold theory
The goal of the present paper is to provide a mathematically rigorous foundation to certain aspects of the theory of rational orbifold models in conformal field theory, in other words the theory of rational vertex operator algebras and their automorphisms. Under a certain finiteness condition on a rational vertex operator algebra V which holds in all known examples, we determine the precise num...
متن کاملLow energy constraints on orbifold models
We review the low energy limits on Kaluza-Klein excitations in orbifold models. New vector-like quarks, as well as new Z ′ gauge bosons, can be accommodated with masses observable at large colliders.
متن کاملHeterotic Orbifold Models and Yukawa Couplings
We classify compactification lattices for supersymmetric Z2×Z2 orbifolds. These lattices include factorisable as well as non-factorisable six-tori. Different models lead to different numbers of fixed points/tori. A lower bound on the number of fixed tori per twisted sector is given by four, whereas an upper bound consists of 16 fixed tori per twisted sector. Thus, these models have a variety of...
متن کاملHigher Order Couplings from Heterotic Orbifold Theory
We calculate couplings of arbitrary order from correlation functions among twisted strings, using conformal field theory. Twisted strings arise in heterotic string compactified on orbifolds yielding matter fields in the low energy limit. We calculate completely the classical and the quantum amplitude including normalization, up to a contribution from Kähler potential. The classical action has s...
