Seminars & Defenses

R2D2: a high pressure xenon TPC for neutrinoless double beta decay search, F. PICQUEMAL (LP2I – Bordeaux) – July 11th 2025 @2pm

The R2D2 collaboration is developing a radial time projection chamber with a fiducial mass of half a tonne of 136Xe at high pressure. This experiment aims to detect neutrinoless double beta decay, which would confirm neutrinos as Majorana particles. The goal is to achieve a tonne-scale, zero-background experiment. Simulations suggest it could set a half-life limit exceeding 10^27 years and constrain neutrino mass, potentially excluding the inverted mass hierarchy region.

FCC-SEED: A Vertex Detector Concept for Future Electron-Positron Colliders at CERN – J. Andrea (IPHC) – June 13rd 2025 @2pm

The European Strategy for Particle Physics is focusing on developing an electron-positron collider, with plans to be detailed in the 2026 update. Proposed projects include CLIC, ILC, and FCC-ee. France is leading the FCC-SEED project to design an advanced vertex detector using thin Monolithic Active Pixel Sensors. This seminar will discuss the FCC-ee project's goals, detector requirements, the FCC-SEED design, and progress on MIMOSIS chips.

Galactic cosmic rays and the role of precision cross-sections – F. Donato (Turin University) – May 23rd 2025 @14h

The unprecedented precision of spatial data challenges our understanding of cosmic rays, stimulating debates on dark matter, the acceleration and transport of cosmic rays, and galactic sources. Interpretations are limited by uncertainties in nuclear cross-sections. A roadmap is proposed to address these issues through ongoing and future measurements.
