Phase transition and shadow behaviors of quintessential black holes in M-theory/superstring inspired models / Belhaj, A. (Rabat U.) ; El Balali, A. (Rabat U.) ; El Hadri, W. (Rabat U.) ; Hassouni, Y. (Rabat U.) ; Torrente-Lujan, E. (Murcia U. ; CERN)
We study $d$-dimensional $AdS$ black holes surrounded by Dark Energy (DE), embedded in $D$-dimensional M-theory/superstring inspired models having $AdS_d \times \mathbb{S}^{d+k}$ space-time with $D=2d+k$. We focus on the thermodynamic Hawking-Page phase transitions of quintessential DE black hole solutions, whose microscopical origin is linked to $N$ coincident $(d-2)$-branes supposed to live in such $(2d+k)$-dimensional models.

Algebraic Cycles and Local Anomalies in F-Theory / Bies, Martin (U. Heidelberg, ITP) ; Mayrhofer, Christoph (Munich U., ASC) ; Weigand, Timo (U. Heidelberg, ITP ; CERN)
We introduce a set of identities in the cohomology ring of elliptic fibrations which are equivalent to the cancellation of gauge and mixed gauge-gravitational anomalies in F-theory compactifications to four and six dimensions. The identities consist in (co)homological relations between complex codimension-two cycles. [...]

Gauge Backgrounds and Zero-Mode Counting in F-Theory / Bies, Martin (U. Heidelberg, ITP) ; Mayrhofer, Christoph (Munich U., ASC) ; Weigand, Timo (U. Heidelberg, ITP ; CERN)
Computing the exact spectrum of charged massless matter is a crucial step towards understanding the effective field theory describing F-theory vacua in four dimensions. In this work we further develop a coherent framework to determine the charged massless matter in F-theory compactified on elliptic fourfolds, and demonstrate its application in a concrete example. [...]

Wilson lines and UV sensitivity in magnetic compactifications / Ghilencea, D.M. (Bucharest, IFIN-HH) ; Lee, Hyun Min (Chung-Ang U.)
We investigate the ultraviolet (UV) behaviour of 6D N=1 supersymmetric effective (Abelian) gauge theories compactified on a two-torus ($T_2$) with magnetic flux. To this purpose we compute offshell the one-loop correction to the Wilson line state self-energy. [...]

Cuts from residues: the one-loop case / Abreu, Samuel (Freiburg U.) ; Britto, Ruth (Trinity Coll., Dublin ; IPhT, Saclay) ; Duhr, Claude (CERN ; Louvain U., CP3) ; Gardi, Einan (U. Edinburgh, Higgs Ctr. Theor. Phys. ; Edinburgh U.)
Using the multivariate residue calculus of Leray, we give a precise definition of the notion of a cut Feynman integral in dimensional regularization, as a residue evaluated on the variety where some of the propagators are put on shell. These are naturally associated to Landau singularities of the first type. [...]

Multiple D3-instantons and mock modular forms II / Alexandrov, Sergei (U. Montpellier, L2C ; CERN) ; Banerjee, Sibasish (IPhT, Saclay) ; Manschot, Jan (Trinity Coll., Dublin ; Hamilton Math. Inst., Dublin) ; Pioline, Boris (CERN ; Paris, LPTHE)
We analyze the modular properties of D3-brane instanton corrections to the hypermultiplet moduli space in type IIB string theory compactified on a Calabi-Yau threefold. In Part I, we found a necessary condition for the existence of an isometric action of S-duality on this moduli space: the generating function of DT invariants in the large volume attractor chamber must be a vector-valued mock modular form with specified modular properties.

Supersymmetric partition functions and the three-dimensional A-twist / Closset, Cyril (CERN) ; Kim, Heeyeon (Perimeter Inst. Theor. Phys.) ; Willett, Brian (Santa Barbara, KITP)
We study three-dimensional $\mathcal{N}=2$ supersymmetric gauge theories on $\mathcal{M}_{g,p}$, an oriented circle bundle of degree $p$ over a closed Riemann surface, $\Sigma_g$. We compute the $\mathcal{M}_{g,p}$ supersymmetric partition function and correlation functions of supersymmetric loop operators. [...]

Higher spin holography and string states on $AdS_{5}S$ / Morales, J F (CERN) ; Samtleben, H
We review the recent proposal for the full string spectrum on Ad Spoint and its agreement with the free SYM spectrum. The spectrum exhibits a hidden symmetry structure larger than expected, with bosonic subgroup SO(10, 2) and thirty-two supercharges. [...]
