“…In this paper, we have studied the attractor mechanism of intersecting black p-branes in non chiral 8D supergravity with 16 supercharges. Actually, this study completes previous results on black attractors in non chiral 8D supergravity with 32 supersymmetries [58] and agrees with the results on higher D-supergravities obtained in [57].…”

“…Guided by the new solutions on extremal BPS and non BPS black attractors in higher dimensional supergravity; in particular those on intersecting attractors obtained first by Ferrara et al in [57], see also [58]; we focus in this paper on non chiral 8D N = 1 supergravity with moduli space SO(2,N ) SO(2)×SO(N ) × SO (1, 1) and study explicitly the attractor mechanism for various configurations of extremal black p-branes with the typical near horizon geometries AdS p+2 × S m × T 6−p−m where p = 0, 1, 2, 3, 4 and m = 2, 3, 4, 5, 6. Actually this analysis completes the results obtained in [58] for the case of maximal N = 2 supergravity in 8D; it also gives new solutions, along the line of [57], classified by SO (N − k) subgroups of the SO (2) × SO (N) symmetry of the moduli space of the non chiral 8D N = 1 supergravity. The interest into this study is also motivated from the two following features: first because of its 16 conserved supersymmetries, extremal black attractors in this 8D supergravity may be viewed as the ancestor of an interesting class of black holes in 7D, 6D, 5D and 4D supergravities [1,5]; in particular in 4D N = 2 and 4D N = 4 resulting from adequate compactifications of the 8D space time down to 4D.…”

“…Because of their specific properties [19]- [38], static, asymptotically flat and spherically symmetric extremal (vanishing temperature for non-zero entropy) black attractors have been investigated for supergravities in diverse space time dimensions; with various numbers of conserved supersymmetries [39]- [56]. Guided by the new solutions on extremal BPS and non BPS black attractors in higher dimensional supergravity; in particular those on intersecting attractors obtained first by Ferrara et al in [57], see also [58]; we focus in this paper on non chiral 8D N = 1 supergravity with moduli space SO(2,N ) SO(2)×SO(N ) × SO (1, 1) and study explicitly the attractor mechanism for various configurations of extremal black p-branes with the typical near horizon geometries AdS p+2 × S m × T 6−p−m where p = 0, 1, 2, 3, 4 and m = 2, 3, 4, 5, 6.

We study intersecting extremal black attractors in non chiral 8D N = 1 supergravity with moduli space SO(2,N ) SO(2)×SO(N ) × SO (1, 1) and work out explicitly the attractor mechanism for various black p-brane configurations with the typical near horizon geometries AdS p+2 × S m × T 6−p−m . We also give the classification of the solutions of the attractor equations in terms of the SO (N − k) subgroups of SO (2) × SO (N ) symmetry of the moduli space as well as their interpretations in terms of both heterotic string on 2-torus and its type IIA dual. Other features such as non trivial SO(1, 7) central charges Z µ 1 ...µ p in 8D N = 1 supergravity and their connections to p-form gauge fields are also given.

Using characters of finite group representations and monodromy of matter curves in F-GUT, we complete partial results in literature by building SO 10 models with dihedral D 4 discrete symmetry. We first revisit the S 4 -and S 3 -models from the discrete group character view; then we extend the construction to D 4 . We find that there are three types of SO 10 × D 4 models depending on the ways the S 4 -triplets break down in terms of irreducible D 4 -representations: (α) as 1 +,− ⊕ 1 +,− ⊕ 1 −,+ ; or (β) 1 +,+ ⊕1 +,− ⊕1 −,− ; or also (γ) 1 +,− ⊕2 0,0 . Superpotentials and other features are also given.

The Asymptotic WGC has been proposed as a special case of the tower WGC that probes infinite distances in the moduli space corresponding to weakly coupled gauge regimes. The conjecture has been studied in M-theory on Calabi-Yau threefold (CY3) with finite volume inducing a 5D effective QFT. In this paper, we extend the scope of the previous study to encompass lower dimensions, particularly we generalise the obtained 5D asymptotic WGC to the effective field theory (EFT$_{3D}$) coupled to 3D gravity that descends from M-theory compactified on Calabi-Yau fourfold with an emphasis on $K3\times K3$. We find that the CY4 has three fibration structures labelled as line Type-$\mathbb {T}^{2}$, surface Type-$\mathbb {S}$ and bulk Type-$\mathbb {V}$. The emergent EFT$_{3D}$ is shown to have 2+2 towers of particles states termed as the BPS $\mathcal {T}_{M_{\mathrm{k}}\rightarrow 0}^{\rm{\small {BPS}}}$ and $\mathcal {T}_{M_{\mathrm{k}}\rightarrow \infty }^{\rm{\small {BPS}}}$ as well as the non-BPS $\mathcal {T}_{M_{\mathrm{k}}\rightarrow 0}^{\rm{\small {N-BPS}}}$ and $\mathcal {T}_{M_{\mathrm{k}}\rightarrow \infty }^{\rm{\small {N-BPS}}}$. To ensure the viability of the 3D Asymptotic WGC, we give explicit calculations to thoroughly test the swampland constraint for both the weakly and strongly gauge coupled regimes. Additional aspects, including the gauge symmetry breaking and duality symmetry are also investigated.
