Integrability in gauge and string theory at IGFAE 30m
I will review progress to obtain exact results in gauge and string theories by means of integrability. I will argue that we can construct deformations to break, for example, the supersymmetry and the conformal invariance of the gauge theory, while preserving the integrable structure. My goal will be that of extending the methods of integrability to obtain exact results also for these deformed models.

Gaseous Detectors for present and future experiments in Rare Event Searches 18m
Gaseous Detectors are playing an increasingly important role in order to boost the scientific reach of experiments where the fidelity to the reaction topology is essential. This is markedly
the case in neutrino physics, direct dark matter searches and some rare nuclear reactions.
We will report the status of these activities at IGFAE.Speaker: Diego Gonzalez Diaz (Universidade de Santiago de Compostela (ES)) -

TRASGOS: Towards a new standard of measuring cosmic rays. 18m
Research in cosmic-rays is of interest in many fields of science; from Astrophysics to Solar Physics, to Forecasting of Geomagnetic storms, to Vulcanology, and much more. For such purposes, many detectors and tools that use different techniques have been designed and are operative all over the world. Of special interest are 'neutron monitors' and 'directional muon telescopes', which perform background surveys of low-energy galactic cosmic-rays.
TRASGO is the acronym of “TRAck reconStructinG bOx” and the name corresponds to a project aiming to the development of a new generation of cosmic-ray tracking detectors. All based on tRPC technology ('timing Resistive Plate Chamber') under which they share their operational capabilities at all levels: acquisition, monitoring, tracking, event reconstruction, and analysis. All these features allow both: the design of Trasgos with a 'broad field of applications', and 'compatibility' (such that any new tool developed for any of them can be used in the rest of stations).
So far three Trasgos have been developed: TRAGALDABAS, MuTT and TRISTAN. These systems have been collecting data for different purposes and at various locations. The program started only a few years ago, therefore, some tools are still under development. Yet, preliminary analyses of the data provided by the different Trasgos has started to show some interesting features, thus proving their research power.

Emergence of collectivity near a critical point 18m
The Relativistic Heavy Ion Collider (RHIC) dedicates significant experimental resources for the search of a critical point (CP) - the endpoint of a first order phase transition at high baryonic densities - in the QCD phase diagram. Hence dynamical simulations of the emergence of collectivity near a CP are of particular interest. With my collaborators I discover that in holographic theories with certain QCD-like features a long-lived quasi-static state may be formed near a critical point (Phys.Rev.Lett. 121 (2018), no.26, 261601). In particular, we show that the standard hydrodynamical relativistic formulation, is incorrect as it fails to describe the pressures of the created plasma. We demonstrate that large second-order spatial derivatives need to be accounted for the fluid description. These will be crucial in the data analysis of the RHIC CP search.

Study of phi-meson production in hadronic and nuclear collisions at very high energies 18m
We expose the experimental and theoretical situation of the interesting case of the production of phi mesons in up to very high energy collisions of hadrons on both nucleon and nuclear targets, and we present a quantitavely good theoretical description of the corresponding experimental data, based on the formalism of the well established Quark-Gluon String Model, that has proved to be valid for a wide energy range. All the available experimental data for phi-meson production in hadron-nucleon collisions on the spectra of secondary phi, and on the ratios of phi/pi(-) and phi/K(-) production cross sections, as well the corresponding ones for phi-meson production on nuclear targets, are considered. In particular, it is shown that the production of phi-mesons on nuclear targets presents unusually small shadow corrections for the inclusive density in the central rapidity region.
