A combination of measurements sensitive to the CKM angle Î³ from the LHCb Collaboration is presented. The inputs are from analyses of time-integrated B+ â†’ DK+ , B0 â†’ DKâˆ—0 , B0 â†’ DK+ Ï€âˆ’ and B+ â†’ DK + Ï€ + Ï€ âˆ’ tree-level decays. In addition, results from a time-dependent analysis of Bs0 â†’ Ds âˆ“ K Â± decays are included. The combination yields Î³ = (72.2 +6.8 âˆ’7.3 ) , where the uncertainty includes systematic effects. The 95.5% confidence level interval is determined to be Î³ âˆˆ [55.9, 85.2] . An updated measurement and its combination with the old result using a frequentist approach is also presented. This results in the most precise measurement of Î³ to date.
