Mon travail sur Belle

The Belle Experiment

The Belle experiment is located in the KEK research centre (Japan) and is primarily devoted to the study of CP violation in the B meson sector.

Belle is placed on the KEKB collider, one of the two currently running "B-meson factories", which produce B – anti-B pairs. To date (January 2007), KEKB has created about 800 million pairs in total, a world record for this kind of colliders. This large sample allows very precise measurements in the physics of beauty mesons.

CP violation studies

One type of CP violation that I have been studying at Belle is induced by interference between decays and mixing in B⁰→D^*π. The full details can be found in this paper.

Soft pion mixing

This was my thesis subject. You can find more about it here.

Distributed offline data processing

During the 4 years I spent in the Belle collaboration, I was in charge of operating and maintaining the "offline distributed reprocessing". This was a highly distributed and automated task, as you can find out from this conference contribution (or directly downloading the poster I presented there).
