DAFNE collider defines its time horizon


The LNF Scientific Committee held last November has discussed the schedule for DAFNE operation in years 2017-2019.

Three are the main scientific goals to be achieved by the experiments running at the Frascati accelerator complex: the completion of the KLOE-2 physics program, collecting 5/fb on tape by March 2018; the preparation of the new interaction region for the SIDDHARTA-2 experiment to take data in 2019; the run of the PADME setup in 2018. This proposed plan has been recently approved by INFN management.

SIDDHARTA-2 aims to observe for the first time the 1S transition line of the kaon-deuterium system, measuring fundamental physics effects in QCD.

PADME, a new beam dump experiment at the Beam Test Facility, will study the possible existence of particles (“dark-photons”) which could explain the observed discrepancies in the measurement of the hadronic corrections to g-2.

DAFNE, in operation since 1998, is expected to terminate its run in collider mode by 2019. Afterwards, several possible re-use of the DAFNE complex are under evaluation, spanning from a world-class accelerator physics test bed to single beam electron or positron facility.
