Description
The decays B(s) -> KS KS proceed via flavor-changing neutral currents that are suppressed in the Standard Model and therefore provide greater sensitivity to new physics. And the latest measurements of their branching fractions exhibit some tension with the SM.
Since the time of the existing measurement, the LHCb experiment has collected a large amount of data and had several improvements to its online selection. This allows one to significantly improve the precision using Run 2 data.
The current work presents a status report on the ongoing measurement of the Bs->KSKS and B0->KSKS branching fractions.
