Periodic Reporting for period 2 - Chiaroscuro (Challenging the Standard Model with the scrutiny of b to qll transitions)

Período documentado: 2023-04-01 hasta 2024-09-30

Resumen del contexto y de los objetivos generales del proyecto

The Chiaroscuro project is probing the potential existence of elementary particles beyond those currently known from the Standard Model of Particle Physics.
During its first 30 months, despite external challenges such as the COVID-19 pandemic and the war in Ukraine, the project progresses well using the data already recorded by the LHCb experiment at CERN. Indeed, due to the delay in the recording of physics quality data with the upgraded LHCb detector, the project extracts as much as possible the full information from the previously recorded data. In parallel, the understanding of the new data is on-going.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

We have performed detailled studies on b→see transitions in particuler for the Bs -> Phi ee decay mode and the B0 -> K*0 ee decay mode

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

We have performed detailed studies on b→see transitions which are of great interest because their comparison may help to shade light on tensions seen in transitions b→s mu mu transitions which are already well studied, contrary to modes involving electrons.

One of the billions of events recorded by the LHCb experiment.
