The LVS parametric tadpole constraint
The large volume scenario (LVS) for de Sitter compactifications of the type IIB string is, at least in principle, well protected from various unknown corrections. The reason is that, by construction, the Calabi-Yau volume is exponentially large. However,

A Note on Toroidal Compactifications of the Type I Superstring and Other Superstring Vacuum Configurations with 16 Supercharges [PDF]
We show that various disconnected components of the moduli space of superstring vacua with 16 supercharges admit a rationale in terms of BPS un-orientifolds, i.e.

The anomaly that was not meant IIB
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.

String Phenomenology: Past, Present and Future Perspectives [PDF]
The observation of a scalar resonance at the LHC, compatible with perturbative electroweak symmetry breaking, reinforces the Standard Model parameterisation of all subatomic data.

Fundamental Units of Measurement and Extra Dimensions
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 ...

BPS Saturated Dyonic Black Holes of $N=8$ Supergravity Vacua [PDF]
We summarize the results for four-dimensional Bogomol'nyi-Prasad- Sommerfield (BPS) saturated dyonic black hole solutions arising in the Kaluza-Klein sector and the three-form field sector of the eleven-dimensional supergravity on a seven-torus.

Supersymmetric Dyons, Superstrings, and Rotating Wormholes
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
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
The large number of moduli fields arising in a generic string theory compactification makes a complete computation of the low energy effective theory infeasible.
