Speaker:    Profesora Paola Arias Reyes  (Universidad San Sebastián; Santiago) Title:   “Axion relics in non-standard cosmologies” Abstract:   I will review our recent findings in axion production by considering a non-standard expansion before Big Bang nucleosynthesis onset. I will start with cold dark matter production through the misalignment mechanism, assuming the energy density of the […]

Speaker:    Dr. Olcyr Summensari (IJCLab, Pôle Théorie, Université Paris-Saclay) Title:   “Understanding the first observation of B→Kνν by Belle-II” Abstract: Recently, the Belle-II experiment reported on the first measurement of B(B→Kνν), which appears to be almost 3σ larger than predicted in the Standard Model (SM). In this talk, I will critically revisit the status of […]

Speaker:    Dr. Claudia Cornella  (Johannes Gutenberg University Mainz, Germany). Title:   “QED corrections to leptonic B decays” Abstract: In this talk I will discuss QED corrections to the weak exclusive process B→ μν, focusing in particular on structure-dependent effects. I will discuss the derivation of a suitable factorization theorem and the related challenges, including the necessity of generalising the notion […]

Speaker:    Professor Julia Harz  (Institute of Physics (WA THEP), Johannes Gutenberg University Mainz, Germany.     Title:   “Confronting Dark Matter Freeze-In during Reheating with Constraints from Inflation” Abstract: I will discuss the production of Dark Matter (DM) in a minimal freeze-inmodel, specifically considering a non-instantaneous reheating phaseafter inflation. I will demonstrate that for low reheating temperatures, bosonic […]

La Dra. Choque fue estudiante de la Universidad de Concepción, luego de sus estudios en esa entidad universitaria, vivió y trabajó en los Países Bajos durante su doctorado; actualmente se encuentra trabajando en la Universidad de Atacama. Title: The evolution of dwarf galaxies in clusters Abstract: Galaxy clusters are the largest gravitationally bound structures in the […]
