The anomaly that was not meant IIB
Fortschritte der Physik, Volume 70, Issue 1, January 2022., 2022 Abstract Type IIB supergravity enjoys a discrete non‐Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group that controls them, modulo some physically motivated assumptions.

Anomalies, dualities, and topology of D = 6 N = 1 superstring vacua [PDF]
Nuclear Physics B, 1996 We consider various aspects of compactifications of the Type I/heterotic $Spin(32)/\Z_2$ theory on K3. One family of such compactifications includes the standard embedding of the spin connection in the gauge group, and is on the same moduli space as the compactification of the heterotic $E_8\times E_8$ theory on K3 with instanton numbers (8,16 ...

Fundamental Units of Measurement and Extra Dimensions
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 The space available to our perception is three-dimensional with full evidence. The development of physics led to the hypothesis of extra dimensions. It is believed that an important role in the unification of physics should play by the Planck units of mass, length and time, built on the universal constants c (the speed of light in a vacuum), G (the ...

Searching the landscape of flux vacua with genetic algorithms
Journal of High Energy Physics, 2019 In this paper, we employ genetic algorithms to explore the landscape of type IIB flux vacua. We show that genetic algorithms can efficiently scan the landscape for viable solutions satisfying various criteria. More specifically, we consider a symmetric T

Supersymmetric Dyons, Superstrings, and Rotating Wormholes
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We construct supersymmetric dyon solutions based on the ‘t Hooft/Polyakov monopole. We show that these solutions satisfy κ‐symmetry constraints and can therefore be generalized to supersymmetric solutions of type I SO(32) string theory. After applying a T‐duality transformation to these solutions, we obtain two D3‐branes connected by a wormhole ...

Swampland variations on a theme by KKLT
Journal of High Energy Physics, 2019 The KKLT scenario in a warped throat, if consistent, provides a concrete counterexample to both the AdS scale separation and the dS swampland conjectures.

Towards a complete mass spectrum of type-IIB flux vacua at large complex structure
Journal of High Energy Physics, 2021 The large number of moduli fields arising in a generic string theory compactification makes a complete computation of the low energy effective theory infeasible.

The “landscape” of Pati–Salam heterotic superstring vacua [PDF]
Fortschritte der Physik, 2010 AbstractThe main aspects of a recently developed method for classification of heterotic superstring vacua in the Free Fermionic Formulation are presented. Using these techniques we classify a big number of approximately 1015 heterotic string vacua with Pati–Salam, SU(4) × SU(2)L × SU(2)R gauge symmetry with respect to their main phenomenological ...

On the stability of string theory vacua
Journal of High Energy Physics, 2022 Vacuum compactifications may suffer from instabilities under small perturbations or tunnel effects; both are difficult to analyze. In this paper we consider the issue from a higher-dimensional perspective.
