25. Matrix models from black hole geometries

Alice Luscher (University of Oxford)

Poster

Supersymmetric and magnetically charged black holes in AdS4 are known to be holographically dual to 3d SCFTs compactified on a Riemann surface.
In the last decade, many observables have been computed on both sides and a remarkable matching has been achieved.
In field theory, the partition function is computed via localization, and it reduces to a matrix model whose eigenvalues, at large N,...

47. Resonance contributions to nucleon spin structure in Holographic QCD

Federico Castellani (Istituto Nazionale di Fisica Nucleare)

Poster

We study polarized inelastic electron-nucleon scattering at low momentum transfer in the Witten-Sakai-Sugimoto model of holographic QCD, focusing on resonance production contributions to the nucleon spin structure functions. Our analysis includes both spin $3/2$ and spin $1/2$ low-lying nucleon resonances with positive and negative parity. We determine, in turn, the helicity amplitudes for...
