Measurement of the CKM angle $γ$ and $B_{s}^{0}$ - $B ˉ_{s}^{0}$ mixing frequency with $B_{s}^{0} \to D_{s}^{\mp} h^{\pm} π^{\pm} π^{\mp}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The CKM angle $γ$ is measured for the first time from mixing-induced $C P$ violation between $B_{s}^{0} \to D_{s}^{\mp} K^{\pm} π^{\pm} π^{\mp}$ and $\bar{B}^0_s \rightarrow D_s^\pm K^\mp…

Search for heavy neutral leptons in $W^{+} \to μ^{+} μ^{\pm} jet$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +980

A search is performed for heavy neutrinos in the decay of a $W$ boson into two muons and a jet. The data set corresponds to an integrated luminosity of approximately $3.0 \text{ fb…
