DREB 2020
The 11th international conference on Direct Reactions with Exotic Beams (DREB2020) is part of the biennial series, which began in 1999 at MSU, East Lansing, at the initiative of physicists working in the field from MSU, IPNOrsay, and FSU. The following meetings were held at Orsay (2001), Guildford (2003), East Lansing (2005), Wako (2007), Tallahassee (2009), Pisa (2012), Darmstadt (2014), Halifax (2016), and Matsue (2018). The scientific program is devoted to the latest experimental and theoretical research and developments in nuclear reactions with exotic nuclei. The topics will include the following subjects relevant to direct reactions:

ARENA 2020
ARENA 2020 is the 9th International Conference on Acoustic and Radio EeV Neutrino detection Activities, a series of events bringing together experts in the use of acoustic and radio techniques for the detection of ultrahighenergy cosmic rays and neutrinos. The new amazing discoveries reported from highenergy neutrino, gammaray and gravitational wave detectors have started the exciting era of multimessenger astronomy, opening a new window to the most extreme universe. ARENA 2020 is the major biannual event for scientists to pioneer, develop and consolidate techniques for ultrahighenergy particle detection, paving the way to the future.

Advanced Computing and Machine Learning
Artificial Neural Networks (ANNs) are computational models able to learn from previously provided datasets, constituting a different paradigm than classical computation algorithms in which tasks are run sequentially. This feature made ANNs an interesting field of study since complex problems in classical computation became easily solved, such as image or sound recognition. Its development was helped by the improvements in hardware capabilities in last two decades, being nowadays an active field of study whose applications go far beyond academic research. In this course, organized by Instituto Galego de Física de Altas Enerxías (IGFAE), basic concepts in ANNs will be introduced at a conceptual and practical level, as well as some interesting applications in Particle Physics and industry. The course will take place at IGFAE from 20th to 24rd of April 2002 and is aimed to researchers, teachers, CIT professionals and students.

Integrability, dualities and deformations
Recent years have seen significant progress in the understanding of deformations of integrable string sigma models, their relation to nonabelian and PoissonLie duality, and their possible AdS/CFT interpretation in terms of noncommutative field theory. Moreover, these models can also be naturally recast in terms of double and exceptional field theory. As such, numerous interesting new connections between these different research areas are developing, promising to shed light on various important open questions. The goal of this workshop is to bring together experts from the fields of
to facilitate exchange of ideas, collaboration, and the development of new insights across these fields.

Complexity and Page curve for an evaporating black hole in flat space
Holographic complexity is conjectured to be dual to a notion of complexity as defined in quantum circuits, which can heuristically be translated to 'how much' during a process the final state differs from an initial state. In the first part of this talk I present nontrivial evidence of this conjecture by obtaining the holographic complexity of an evaporating black hole in the semiclassical RussoThorlaciusSusskind (RST) model, which is a twodimensional dilaton gravity model with flat spacetime asymptotics. In the second part of this talk I will discuss how to explicitly obtain the Page curve for the same model, which implies a unitary evaporation process. I will use methods recently applied to obtain Pages curves for asymptotically AdS spacetimes and discuss some implications of this result. This is an online seminar that will be broadcasted via Jitsi .

Momentum broadening in the Glasma
Jets created in relativistic heavyion collisions provide important information about the whole spacetime evolution of the medium. While much work has been done on jets interacting with the hydrodynamic quarkgluon plasma stage, modifications due to shortlived preequilibrium stage are usually neglected. In this talk I will present our latest results on jet momentum broadening occurring in the preequilibrium Glasma based on the Color Glass Condensate (CGC) framework. I show how we can compute the transverse momentum acquired by a highly energetic colored particle through interactions with the classical color fields in the Glasma in a manifestly gaugeinvariant way. We apply these methods semianalytically to the dilute Glasma and, using realtime lattice gauge simulations, also to the dense Glasma created in heavyion collisions. One particularly surprising result is that momentum broadening in the Glasma occurs anisotropically, with more efficient broadening in rapidity compared to azimuthal broadening. This is an online seminar that will be broadcasted via Jitsi.

Relativistic Fluid Dynamics: From Particle Colliders to Neutron Star Mergers
Heavyion collision experiments have provided overwhelming evidence that quarks and gluons, the elementary particles within protons and neutrons, can flow as a nearly frictionless, strongly interacting relativistic liquid over distance scales not much larger than the size of a proton. On the other hand, with the dawn of the multimessenger astronomy era marked by the detection of a binary neutron star merger, it became imperative to understand how extremely dense fluids behave under very strong gravitational fields. Therefore, three of the most cuttingedge experimental apparatus in modern science, the Relativistic Heavy Ion Collider (RHIC), the Large Hadron Collider (LHC), and the Laser Interferometer GravitationalWave Observatory (LIGO) are now taking data whose description requires a major overhaul of our current understanding of fluid dynamics. In this seminar I will discuss the new developments that have contributed to redefine the onset of relativistic fluid dynamics and its extension towards the farfromequilibrium regime. New results involving viscous fluids and their coupling to general relativity will be presented. These results pave the way for the inclusion of dissipative effects in neutron star merger simulations.

System size scan of D meson ${R}_{\text{AA}}$ and ${v}_{n}$ using PbPb, XeXe, ArAr, and OO collisions
Experimental measurements indicate no suppression (e.g. ${R}_{\mathrm{pPb}}\sim 1$) but a surprisingly large D meson ${v}_{2}$ was measured in pPb collisions. In order to understand these results we use Trento+vUSPhydro+DABMOD to make predictions and propose a system size scan at the LHC involving ${}^{208}PbPb$, ${}^{129}XeXe$, ${}^{40}ArAr$ and ${}^{16}OO$ collisions. We find that the nuclear modification factor approaches unity as the system size is decreased, but nonetheless, in the 010% most central collisions ${v}_{2}\left\{2\right\}$ is roughly equivalent regardless of system size. These results arise from a rather nontrivial interplay between the shrinking path length and the enhancement of eccentricities in small systems at high multiplicity. Additionally, our best fit Langevin and energy loss models demonstrate different sensitivities to system size effects, demonstrating that a system size scan may be able to constrain different approaches. Finally, we also find a surprising sensitivity of D mesons ${v}_{2}\left\{2\right\}$ in 010% at ${p}_{\text{T}}=\mathrm{25}$GeV to the slight deformation of ${}^{129}Xe$ recently found at LHC.

Masterclass
Un ano máis, o Instituto Galego de Física de Altas Enerxías (IGFAE) da Universidade de Santiago de Compostela (USC), en colaboración coa Sociedade Europea de Física, o CERN (Organización Europea para a Investigación Nuclear) e Fermilab (Laboratorio Nacional Fermi), organiza unha Masterclass de Física de Partículas o vindeiro xoves 12 de marzo para estudantes do último curso de bacharelato. Promovida polo “Grupo Internacional de Divulgación de Física de Partículas” e denominada “Física de Partículas coas mans”, a masterclass consistirá nunha serie de conferencias sobre a Física de Partículas actual, ademais dunha práctica por ordenador realizada en grupo, os resultados da cal serán discutidos mediante videoconferencia con outros centros europeos que organizan simultaneamente unha xornada idéntica na que participan cada ano máis de 13.000 alumnos de 52 países.
