“…• Generalization to black strings and other extended objects, in general dimensions, and their possible explosions upon the introduction of scalar potentials. A particular instance of this is the fate of the 4d EFT strings in [23][24][25] in the presence of potentials growing fast at the string core.…”

“…In particular, the end of the world branes in dynamical cobordisms [7][8][9][10][11] (see also [12] for the swampland cobordism conjecture, [13][14][15][16] for early work and [17][18][19][20][21][22] for other related recent developments), display interesting scaling relations among the spacetime curvature and the spacetime and field theory distances. Other setups are 4d EFT strings [23][24][25], and small black holes (see e.g. [26] for a review, and [27] for discussion in the swampland context).…”

Small black holes are a powerful tool to explore infinite distances in moduli spaces.However, we show that in 4d theories with a scalar potential growing fast enough at infinity, it is energetically too costly for scalars to diverge at the core, and the small black hole puffs up into a regular black hole, or follows a runaway behaviour.We derive a critical exponent characterizing the occurrence or not of such small black hole explosions, both from a 4d perspective, and in the 2d theory after an S 2 truncation.The latter setup allows a unified discussion of fluxes, domain walls and black holes, solving an apparent puzzle in the expression of their potentials in the 4d N = 2 gauged supergravity context.We discuss the realization of these ideas in 4d N = 2 gauged supergravities. Along the way we show that many regular black hole supergravity solutions in the literature in the latter context are incomplete, due to Freed-Witten anomalies (or duals thereof), and require the emission of strings by the black hole.From the 2d perspective, small black hole solutions correspond to dynamical cobordisms, with the core describing an end of the world brane. Small black hole explosions represent obstructions to completing the dynamical cobordism. We study the implications for the Cobordism Distance Conjecture, which states that in any theory there should exist dynamical cobordisms accessing all possible infinite distance limits in scalar field space. The realization of this principle using small black holes leads to non-trivial constraints on the 4d scalar potential of any consistent theory; in the 4d N = 2 context, they allow to recover from a purely bottom-up perspective, several non-trivial properties of vector moduli spaces near infinity familiar from CY 3 compactifications.

“…Such a step can be motivated by the completeness hypothesis [96]. This approach has been recently pursued in [97][98][99][100][101] (see [102] for a similar work in five dimensions), based on the manifest supersymmetric formalism developed in [103,104], but the history of supergravity coupled to extended objects dates back to [105,106].…”

In these proceedings, we review recent progress in analyzing the behavior of lower-dimensional supergravity theories when combined with swampland conjectures. We show that within supergravity the effectiveness and usefulness of swampland conjectures gets amplified, existing criteria can be intertwined and also new ones can be uncovered. Furthermore, we elaborate on some previously unpublished work. This includes evidence for the possible existence of a novel conjecture on Yukawa couplings and an argument to constrain large classes of D-term inflationary models using known conjectures.

In this contribution, we review a general argument showing that de Sitter critical points of extended supergravity are in tension with the magnetic weak gravity conjecture if the gravitino mass is vanishing. Motivated by this assumption, we review then the gravitino conjecture, which states that the limit of vanishing gravitino mass is pathological for the effective field theory description. Finally, we discuss more in general the fate of de Sitter critical points (with massless gravitini) in supergravity and comment on extensions of these works along various directions. Part of the material here presented is unpublished.
