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).

The Instituto Galego de Física de Altas Enerxías (IGFAE), a joint centre of the University of Santiago de Compostela (USC) and the Xunta de Galicia, will host, from 8 to 12 June, 2026, the conference ‘Data Science and Complexity in Fundamental Physics and the Bridge to the Industry and Society‘.

The meeting aims to promote dialogue between academia and industry, as well as to highlight professional opportunities for people interested in data science and its applications to society and business.

The meeting, consisting of a school for young researchers as well as a symposium with the participation of companies from a wide range of sectors, with data science as nexus, will be held for the second time in Santiago de Compostela after previous editions in Portugal (Lisbon, Braga and Coimbra).

The diagrammatic approach to calculating group theoretical factors is a powerful technical tool in quantum field theory. The diagrams used in these calculations are known as "birdtracks" and they complement the mainstream approaches based on Feynman diagrams. In the context of quantum chromodynamics, SU(3), birdtracks intuitively represent the color flow of the process being examined and can be easily extended to any value of N.

This series of lectures introduces elementary birdtracks and provides practice exercises. Topics of interest include constructing projection operators and invariant charges, their relationship with permutation operators and Young-diagrams, and evaluating Wilson lines correlators in the Gaussian approximation. Although the lectures primarily focus on the SU(N) group, the birdtrack approach is generic and can be applied to other groups, such as the Clifford group.

The 7th edition of "Beyond the Flavour Anomalies" workshop will take place in Santiago de Compostela, Spain, from April 15th to April 17th, 2026. Hosted by the Instituto Galego de Física de Altas Enerxías (IGFAE) and the University of Santiago de Compostela (USC), the workshop will bring together experts from theory and experiment to discuss the latest developments in flavour physics, right after the annual winter conferences.

The event will feature presentations on Flavour Physics with experimental overviews and theoretical perspectives, covering both Standard Model and Beyond Standard Model physics. In order to encourage more informal, fruitful and insightful discussions, the number of participants is limited and participation is by invitation only.
