TDAQ lab in Bologna

Contacts: MauroVilla, CarlaSbarra

Here we develop/test new firmware for the LUMAT card, as well as new electronics boards/firmware with larger scope. The software used for development and testbeams is the atlas TDAQ.

Top Quark


Cross Section

Contacts: LorenzoBellagamba, GrazianoBruni, MassimoCorradi, RiccardoDiSipio

Our aim is mainly to cross-validate the cut-flow of the cut-and-count analysis and to combine the measurements of e/mu channels. We developed a technique based on Bayes' theorem which make use of Markov Chain Monte Carlo as implemented in BAT to integrate out the systematics and obtain the posterior pdf.

ttbar Mass

Contacts: LorenzoBellagamba, GrazianoBruni, RiccardoDiSipio, MarinoRomano

We aim to measure the mass of the ttbar system. This quantity is sensible to new production channels, e.g. Z' boson.
