SuperB was a proposed high-luminosity electron-positron collider that was to be used as a B-factory. The project started around 2001 and it was cancelled by the Italian government on 27 November 2012. The collider was initially supposed to be built on University of Rome 'Tor Vergata' campus near Rome, Italy, under the supervision of the Istituto Nazionale di Fisica Nucleare. The location later changed to the site of Frascati National Laboratory (geographically, the change was only a few kilometers). The title SuperB referred to the fact that the collider was expected to produce very large quantities of B mesons.

| - SuperB was a proposed high-luminosity electron-positron collider that was to be used as a B-factory. The project started around 2001 and it was cancelled by the Italian government on 27 November 2012. The collider was initially supposed to be built on University of Rome 'Tor Vergata' campus near Rome, Italy, under the supervision of the Istituto Nazionale di Fisica Nucleare. The location later changed to the site of Frascati National Laboratory (geographically, the change was only a few kilometers). The title SuperB referred to the fact that the collider was expected to produce very large quantities of B mesons. In the initial Conceptual Design Report, the accelerator was conceived to be a circular (actually, quite hexagonal) double ring 2249 meters in circumference; it would have accelerated electrons to 7 GeV and positrons to 4 GeV before colliding them. The project suggested to cut cost by reusing hardware from the PEP-II accelerator, which was decommissioned before the proposed start of building of SuperB. Also the BaBar detector's components would be reused in the project. It was estimated that the building and commissioning of the collider would take 5 years. Not much was said about the location where accelerator would be built (apart from the accelerator being built in Italy, perhaps near Rome). At the back cover of CDR the intended location was shown to be the campus of University of Rome Tor Vergata. In later plans, the accelerator changed shape into an ellipse shape with a linear injector part. The accelerator also became smaller, only 1250 meters in circumference (however the energies of the beams did not change), and finally the location changed to the site of Frascati National Laboratory. The plan was to have SuperB in an underground (quite shallow) tunnel below the Frascati National Laboratory's buildings. It was still planned to reuse PEP-II and BaBar hardware. The budget for the whole project was estimated to be of the order of 1 billion euro at the time of cancellation. (en)

- SuperB è una collaborazione internazionale che aveva l'obiettivo di costruire un acceleratore di particelle che producesse, tramite collisioni di elettroni e positroni un gran numero di particelle pesanti, contenenti quark di diversi sapore. Tecnicamente è una "e+e- Super Flavor Factory asimmetrica ad alta luminosità (≥)". Il programma scientifico di SuperB è focalizzato sulla Nuova Fisica ed è complementare con i programmi del Large Hadron Collider e dell'International Linear Collider. Gli studi possibili con questo acceleratore costituiranno una opportunità unica per la comprensione profonda di Nuova Fisica scoperta con LHC, e qualora non fosse trovata ad LHC, potrà spingere la sua sensibilità a discernere segnali di NF presente ad energie più alte di LHC aiutando a definirne la scala. Con gli esperimenti della SuperB i principi della fisica quantistica ci permetteranno di vedere, per un piccolissimo istante e come illuminate da un flash, materia e antimateria così come erano 14 miliardi di anni fa, subito dopo il Big Bang. La SuperB produrrà e registrerà decine di miliardi di queste istantanee, come tante dettagliate fotografie tridimensionali dell'universo primordiale. Il SuperB Conceptual Design Report, firmato da 85 istituzioni di tutto il mondo, è stato pubblicato nel marzo 2007. Il progetto SuperB ha ottenuto un finanziamento del CIPE, e sarà realizzato nell'area dell'Università degli Studi di Roma "Tor Vergata". In data 28 novembre 2012 il progetto SuperB è stato soppresso.
