Speakers: Giulio Dujany (CNRS – IPHC)
The Belle II experiment at the SuperKEKB energy-asymmetric e+ e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 6×10^35 cm^−2 s^−1 and the Belle II experiment aims to record 50 ab^−1 of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the Cabibbo-Kobayashi-Maskawa(CKM) matrix, the matrix elements and their phases, with unprecedented precision and explore flavor physics with B and charmed mesons, and τ leptons. Belle II has also a unique capability to search for low mass dark matter and low mass mediators. In this presentation, we will review the status of the Belle II detector, the results of measurements with the first data collected and the prospects for physics at Belle II.

Skipper sensors: from world-leading Dark Sector limits in DAMIC-M to the future of low-noise imaging?
Speakers: Xavier Bertou (IJCLab) Skipper CCD technology has recently unlocked unprecedented sensitivity to ionization signals as faint as a single electron, enabling new frontiers in direct dark matter searches. As a result, the DAMIC-M experiment at the Modane Underground Laboratory, based on Skipper CCDs, has delivered the most stringent constraints to date on sub-MeV dark matter interacting with electrons, probing both freeze-out and freeze-in scenarios in the dark sector for the first time. While Skipper CCDs represent a technological breakthrough by overcoming the readout noise floor of conventional CCDs, they do so at the cost of readout time. New recent improvements, including MAS-CCD, SiSeRO, and CMOS Skipper architectures, combine faster readout with Skipper-level performance. I will detail those and focus on the possibility of designing a future low-noise imager using Skipper CMOS technology. https://indico.in2p3.fr/event/38024/
