文摘

The effects of color reconnection (CR) at \({\mathrm e}^+{\mathrm e}^-\) colliders are revisited, with focus on recently developed CR models. The new models are compared with the LEP2 measurements for \({\mathrm e}^+{\mathrm e}^- \rightarrow {\mathrm W}^+{\mathrm W}^- \rightarrow {\mathrm q}_1 \overline{\mathrm q}_2 {\mathrm q}_3 \overline{\mathrm q}_4\) and found to lie within their limits. Prospects for constraints from new high-luminosity \({\mathrm e}^+{\mathrm e}^-\) colliders are discussed. The novel arena of CR in Higgs decays is introduced, and it is illustrated by shifts in angular correlations that would be used to set limits on a potential CP-odd admixture of the 125 GeV Higgs state.
