In this talk I will present a systematic procedure to compute the effective action that governs the dynamics of Goldstone degrees of freedom associated to the breaking of spacetime symmetries in the formation of domain wall and string defects, as well as their couplings to other massive modes such as bound states. I will show how the predictions of such effective action compare to the true, field theoretical evolution for collapsing domain walls, and argue that no curvature corrections should appear in the case of collapsing strings, as opposed to previous claims in the literature.

O IGFAE e o CITMAga (Centro de Investigación e Tecnoloxía Matemática de Galicia) unen forzas para organizar un encontro co que se pretende promover a internacionalización das e dos estudantes nas primeiras etapas da carreira investigadora. Oito relatores con experiencia investia compartirán as súas propias experiencias durante a xornada. O rexistro é gratuíto, e pode formalizarse ata o venres 13 de decembro nesta ligazón.

Directores: Diego González Díaz (IGFAE) and Justo Martín Albo Simón (IFIC)

A sede do IGFAE acolle unha nova edición do ciclo Transfronteirizas: conversas de arte e ciencia. Nesta ocasión, o investigador Héctor Álvarez e a artista Paula Quintas compartirán co público asistente o proceso de creación do seu proxecto Mundo Quark. Danza Cuántica. Esta iniciativa artística parte do Modelo Estándar para representar as partículas elementais e as interaccións entre elas a través da danza e o movemento corporal, explorando as interseccións entre ambas disciplinas.

The Auditorio Abanca in Santiago de Compostela will host on Wednesday 27 November( 20.00 hours), the conference by the Greek-French physicist Jean Iliopoulos, one of the three authors (together with Sheldon Glashow and Luciano Maiani) of the GIM mechanism, the theoretical proposal which, in 1970, postulated the existence of the charmed quark. Iliopoulos will tell the audience how the discovery he promoted from a theoretical perspective brought about a radical change in the perception of the fundamental structure of matter, leading to a new vision of the nature of the fundamental forces.

After graduating from the Polytechnic School of Athens, Iliopoulos (Kalamata-Greece, 1943), and working at institutions such as CERN and Harvard, he spent much of his career at the *École normale supérieure de Paris, being one of the founders of its prestigious Laboratory of Theoretical Physics, which he directed between 1991-1995 and 1998-2002. He has been a member of the French Academy of Sciences since 2002, and received important awards such as the Dirac Prize (2007) together with his colleague Luciano Maiani, and the European Physical Society Prize in High Energy and Particle Physics (2011), together with Maiani and Glashow.
