8. FPGA-Aware Graph Neural Networks for the CMS Phase-2 Muon Trigger

Santiago Folgueras (Universidad de Oviedo)

1/6/26, 9:45

Real-time event reconstruction at the HL-LHC demands machine-learning algorithms that fit strict FPGA latency, resource, and throughput budgets, motivating a co-design between model architecture and firmware implementation. We present an FPGA-aware Graph Neural Network targeting the CMS Overlap Muon Track Finder (OMTF), exploring quantisation schemes from float32 down to INT8-PO2 together with...

13. Phenomenological properties of String Theory vacua

Giuseppe Sudano (ICTEA - Universidad de Oviedo)

1/6/26, 10:00

String theory is one of the leading candidates for a consistent theory of quantum gravity, naturally predicting supersymmetry and extra dimensions. More realistic four-dimensional models can be obtained using an effective field theory approach. String vacua play an important role in this context: their phenomenological properties will be discussed, with particular emphasis on open-string effects.

18. Detecting Irregular Photometric Signals (DIPS OJOS)

Enrique Díez Alonso (Instituto de Ciencias y Tecnologías Espaciales de Asturias (ICTEA))

1/6/26, 10:15

The era of large space-based photometric surveys (Kepler, TESS) has required the use of automated algorithms for the massive detection of exoplanets. However, these methods, while necessary to handle enormous amounts of data, often overlook subtle signals present within transits, such as starspot crossings, flares, mutual planet-planet phenomena, or transit duration variations. To recover this...

9. Measurement of WZ single and double polarization with the CMS experiment at CERN

Laura García Díaz

1/6/26, 10:30

The production of dibosons (VV, where V can be either a W or Z boson) holds a crucial role in the understanding of the electroweak sector of the Standard Model as well as its possible extensions. The WZ process allows to test several theoretical features of interest, such as charge asymmetries in the initial state, measurement of polarization fractions for W and Z bosons and provides direct...

23. Magnification bias of submillimetre galaxies as a probe of dark energy evolution

Rebeca Fernández Fernández (Universidad de Oviedo, ICTEA)

1/6/26, 10:45

We present an ongoing tomographic analysis of cosmological constraints from the magnification bias of high-redshift submillimetre galaxies.

The analysis explores ΛCDM, wCDM and CDM...

24. Unraveling the Universe with JWST from galaxies to the Solar System.

Laura Hermosa Muñoz (CAB CSIC-INTA)

1/6/26, 11:00

Since its launch, the James Webb Space Telescope (JWST) has opened a new window to study the universe in the infrared with an unprecedented combination of high spatial and spectral resolution. Its spectral capabilities, thanks to the use of integral field spectroscopy (IFS) in both the near and the mid-infrared, allow to analyse the complex interplay between gas, dust, ices and molecules in...

10. Collectivity from Quantum Diffraction

Erik Carrió Úbeda (ICTEA - Universidad de Oviedo)

1/6/26, 15:45

When we smash large ions together at nearly the speed of
light, we create the most perfect fluid in the universe - the
quark-gluon plasma. Its strong collective behavior, well described by
relativistic hydrodynamics, has been also observed in smaller
collision systems, puzzling the whole particle physics community. In
this talk I will present a new mechanism generating...

Juan Antonio de Abol-Brasón Vázquez de Prada (ICTEA - Universidad de Oviedo)

1/6/26, 17:00

Atmospheric turbulence constitutes one of the main limitations for large ground-based telescopes. In both astronomy and free-space optical communications (FSOC), turbulence degrades wavefront quality and reduces the stability of optical links. This work presents the development and implementation of Machine Learning–based methodologies for wavefront reconstruction and compensation, together...

19. Automation of detection, localization, and classification of artificial objects in Earth orbit using small telescopes.

Ramón Hevia

1/6/26, 17:15

Since the launch of Sputnik 1 in 1957, the number of satellites in orbit has increased exponentially. The recent deployment of constellations such as Starlink has intensified the impact on astronomical observations, especially due to satellites in Low Earth Orbit (LEO). Although these systems provide major benefits in communications, meteorology, remote sensing, and defense, they also degrade...

3. Neuromorphic computing, optoelectronics, and artificial intelligence for calorimetry: the PHINDER EIC Pathfinder Open Project

5. Graph Neural Networks for Displaced Muon Classification

Elena Aller Gutierrez (ICTEA - Universidad de Oviedo)

2/6/26, 10:30

Displaced muons constitute one of the key signatures of numerous Beyond the Standard Model (BSM) theories involving Long-Lived Particles (LLPs). Furthermore, the detection and selection of these kind of objects represents a technical challenge. In fact, the trigger system operates under severe latency requirements, deciding whether each recorded event should be kept or not within extremely...

12. The Landscape and the Swampland: Searching for Consistent Universes

Luis Germán Varona Galán (ICTEA - Universidad de Oviedo)

2/6/26, 10:45

String theory aims to unify quantum physics and gravity into what is called a theory of Quantum Gravity. One of its most surprising features is that it allows an enormous number of possible universes, each arising from different ways of compactifying extra spatial dimensions, forming what is known as the Landscape. But are all these universes physically consistent? The Swampland Program...
