1. Stripped-Envelope Supernovae for QCD Axion Detection

Francisco Rodríguez Candón (Universidad de Zaragoza)

16/12/2025, 11:30

The QCD axion, arising from the Peccei–Quinn solution to the strong-CP problem, remains one of the most compelling candidates for physics beyond the Standard Model and for the dark matter of the Universe. Core-collapse galactic supernovae provide exceptional laboratories for probing such particles, as the extreme densities and temperatures inside the proto-neutron star lead to copious axion...

12. Prospects of CMB B-modes with future CMB and large-scale structure experiments

Chandra Shekhar Saraf (Korea Astronomy and Space Science Institute)

17/12/2025, 12:30

In the era of high precision Cosmic Microwave Background (CMB) anisotropy measurements, detection of primordial B-modes polarisation will be one of the goals of the current and upcoming CMB experiments. In this talk I will present the methodology of detecting B-modes from Simons Observatory-like CMB experiment. I will also discuss how including probes of large scale structure can improve the...

6. GeV-ALP searches with ALP-aca

Jorge Alda (Università degli Studi di Padova)

18/12/2025, 12:30

Axion-Like particles (ALPs) are pseudoscalar neutral particles that are predicted by many New Physics theories. The GeV mass range is interesting for several reasons: the constraints in parameter space are weaker, the flavour structure of the couplings to SM fermions plays an important role, and it can be explored by different experiments such as BESIII, Belle II and LHCb. But there is also an...

11. Many-body wavefunctions from conformal field theory

Adrián Franco Rubio (U. Complutense de Madrid)

19/12/2025, 13:30

In quantum many-body physics, ansatz wavefunctions and toy models can provide useful information about entanglement patterns and phases of matter. In this talk, we introduce families of spin chain wavefunctions defined in terms of correlators in chiral conformal field theory, which interpolate between well-known gapped and gapless exactly solvable models, and give rise to a certain...
