The Quantum Dynamics of Heterotic Vortex Strings
We study the quantum dynamics of vortex strings in N = 1 SQCD with U(Nc) gauge group and Nf = Nc quarks. The classical worldsheet of the string has N = (0, 2) supersymmetry, but this is broken by quantum effects. We show how the pattern of supersymmetry breaking and restoration on the worldsheet captures the quantum dynamics of the underlying 4d theory. We also find qualitative matching of the ...
متن کاملHeterotic Cosmic Strings
We show that all three conditions for the cosmological relevance of heterotic cosmic strings, the right tension, stability and a production mechanism at the end of inflation, can be met in the strongly coupled M-theory regime. Whereas cosmic strings generated from weakly coupled heterotic strings have the well known problems posed by Witten in 1985, we show that strings arising from M5-branes w...
متن کاملStable and Metastable Cosmic Strings in Heterotic M-Theory
We address the question of finding stable and metastable cosmic strings in quasirealistic heterotic M-theory compactifications with stabilized moduli. According to Polchinski’s conjecture, the only stable strings in the absence of massless fields are Aharonov-Bohm strings. Such strings could potentially be created in heterotic compactifications as bound states of open membranes, five-branes wra...

N=2 heterotic strings may provide a window into the physics of M-theory radically different than that found via the other supersymmetric string theories. In addition to their supersymmetric structure, these strings carry a four-dimensional self-dual structure, and appear to be completely integrable systems with a stringy density of states. These lectures give an overview of N=2 heterotic string...
متن کاملHeterotic Coset Models of Microscopic Strings and Black Holes
Following a recent conjecture by Lapan, Simons and Strominger, we revisit and discuss an intrinsically heterotic class of conformal field theories, emphasizing their Lagrangian construction as asymmetrically gauged WZW models, which may be useful in several applications to the study of supersymmetric strings and black holes in heterotic and type II string theory compactified on T 6 and K3 × T 2...
