99. Axion-Higgs interplay in the two Higgs-doublet model

Domenec Espriu Climent (University of Barcelona (ES))

We study the Dine-Fischler-Srednicki (DFS) model in the light of the recent Higgs LHC results and electroweak precision data. The DFS model is a natural extension of the two-Higgs doublet model endowed with a Peccei-Quinn symmetry and leading to a physically acceptable axion. For generic couplings, the model reproduces the minimal Standard Model showing only tiny deviations (extreme decoupling...

2. Bottom-up holographic approach to QCD

Sergey Afonin (Saint Petersburg State University)

08/09/2015, 12:00

One of the most known result of the string theory consists in the idea that some strongly coupled gauge theories may have a dual description in terms of a higher dimensional weakly coupled gravitational theory --- the so-called AdS/CFT correspondence or gauge/gravity correspondence. The attempts to apply this idea to the real QCD are often referred to as "holographic QCD" or "AdS/QCD...

19. Cold holographic matter

Prof. Alfonso Ramallo (University of Santiago de Compostela)

08/09/2015, 12:30

After a brief review of the Landau Fermi liquid theory, we will discuss a holographic modeling of cold matter in terms of D-brane intersections. We will analyze the different regimes of these systems as a function of the temperature and, in particular, their zero-sound and diffusion modes.
