The IGFAE Scientific Advisory Board will meet at the Institute facilities on November 5th and 6th, 2026.

REF 2026 is the 13th edition in the series of workshops on Resummation, Evolution and Factorization. The workshop brings together specialists in different areas, from effective field theory to lattice to QCD factorization methods. It will be held at the Instituto Galego de Física de Altas Enerxías (IGFAE) from the University of Santiago de Compostela (Galicia, NW Spain).

This talk will provide you a glimpse about the world of neutrinos -nearly massless "ghost particles", which are very abundant and everywhere. 

We trace their journey from the hearts of stars to cutting-edge labs in Japan, exploring the mind-bending theory of neutrino oscillations, where these particles change their type while traveling.

We provide an overview of state-of-the-art detection facilities: the iconic Super-Kamiokande, the long-distance T2K experiment, and the future Hyper-Kamiokande, a detector so sensitive it could explain why the universe is made of matter instead of nothingness. Finally, we show how this "invisible" science helps society, from monitoring nuclear reactors to peering inside the Earth\'s core.

ECRS 2026 is the 29th in a series of European Cosmic Ray Symposia, which are held every 2 years in one of European countries.

The main goal of the Symposia is to gather European Physics community performing research of cosmic rays and related fields, to present recent results, newly emerging ideas and forthcoming experiments.

Recent experiments have shown that the mean transverse momentum $| langle p_T | rangle $ of outgoing particles increases as a function of the particle multiplicity in ultracentral nucleus-nucleus collisions at collider energies.

This increase was originally predicted on the basis of simulations where the multiplicity increase occurred at constant volume, so that it implied a larger density and temperature. However, recent state-of-the-art simulations have shown that, for some models of initial condition, the volume may vary with the multiplicity in ultracentral collisions. We elucidate this effect by analytically relating the variation of the volume to the radial distribution of the one- and two-point functions of the fluctuating density field. We show that the volume variation is small if the total entropy of the ultracentral collisions scales with the mass number of the colliding isotopes. We argue that probing detailed transverse distributions of initial-state fluctuations through the ultracentral $| langle p_T | rangle $ has nontrivial implications for models of nuclear structure and of the pre-equilibrium stages.
