The χc1(3872) and its radiative decays at LHCb / Polyakov, Ivan (speaker) (NRC "Kurchatov Institute" (ITEP) (RU))
The spectroscopy of exotic hadrons is a promising way to reveal how non-perturbative QCD works. As the first established exotic hadron, the χc1(3872) is also the most studied today. In this seminar we will discuss what can already be concluded from more than 20 years of its experimental study, and what more can and can't be learned from its radiative decays [...]

Resurgence and non-perturbative topological strings / Marino Beiras, Marcos (speaker) (University of Geneva, Switzerland)
The string perturbative series diverges factorially, and it is expected that this behavior is related to the existence of non-perturbative effects due to D-branes. Although these ideas can be made precise in the case of non-critical strings, little is known in other situations. [...]

Quantum Entanglement Entropy in String Theory / Dabholkar, Atish (speaker) (ICTP)
I discuss physical motivations from black hole physics and holography for expecting finite quantum entanglement entropy in quantum gravity. I describe recent and earlier results in defining such a notion in perturbative string theory by a stringy analog of the replica method using ZN orbifolds constructed for any odd positive integer N. [...]

The entropy of Holographic CFTs at large charge and angular momentum / Minwalla, Shiraz (speaker) (Tata Institute of Fundamental Research, Mumbai, India)
Black holes in AdS$_d$ (with $d\ geq 4$) are always unstable at large angular momentum, and sometimes unstable at large charge. In this talk we present proposals for the end point of these instabilities. [...]

Nonsupersymmetric branes in heterotic string theories / Yonekura, Kazuya (speaker) (Tohoku University, Japan)
I will talk about non-BPS branes in heterotic superstring theories. These branes are characterized by topologically nontrivial gauge field configurations on the sphere surrounding the branes. [...]

A Holographic Triptych at Large N / Bobev, Nikolay (speaker) (KU Leuven)
I will summarize recent results, obtained using supersymmetric localization, about the large N limit of path integrals of 3d SCFTs arising on the worldvolume of N M2-branes placed on compact Euclidean manifolds. The leading N^3/2 term in the large N expansion of these "free energies" receives 1/N, log(N), as well as exponentially suppressed corrections. [...]

Bootstrapping the AdS Virasoro-Shapiro amplitude / Hansen, Tobias (speaker) (Durham University , UK)
The formulation of the worldsheet theory for type IIB strings on AdS5xS5 remains an important open problem. Luckily, at least the corresponding AdS Virasoro-Shapiro amplitude can be bootstrapped in a small curvature expansion. [...]
