Search for W boson decays to three charged pions
For the first time, a search for the rare decay of the W boson to three charged pions has been performed. Proton-proton collision data recorded by the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 77.3 fb−1, have been analyzed. No significant exc...

| description | For the first time, a search for the rare decay of the W boson to three charged pions has been performed.
Proton-proton collision data recorded by the CMS experiment at a center-of-mass energy of 13 TeV,
corresponding to an integrated luminosity of 77.3 fb−1, have been analyzed. No significant excess is
observed above the background expectation. An upper limit of 1.01 × 10−6 is set at 95% confidence level
on the branching fraction of the W boson to three charged pions. This provides a strong motivation for
theoretical calculations of this branching fraction. |
