| dc.description.abstract | A search for the rare decay D0 --> m+m- is reported using proton-proton collision events at V¯s = 13.6 TeV collected by the CMS detector in 2022-2023, corresponding to an integrated luminosity of 64.5 fb-1. This is the first analysis to use a newly developed inclusive dimuon trigger, expanding the scope of the CMS flavor physics program. The search uses D0 mesons obtained from D*+ --> D0p+ decays. No significant excess is observed. A limit on the branching fraction of B(D0 --> m+m-) <2.4×10-9 at 95% confidence level is set. This is the most stringent upper limit set on any flavor changing neutral current decay in the charm sector. | es_ES |
| dc.description.sponsorship | We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort. In addition, we gratefully acknowledge the computing centres and personnel of the Worldwide LHC Computing Grid and other centres for delivering so effectively the computing infrastructure essential to our analyses.
