Search for $C P$ violation in the phase space of $D^{0} \to π^{+} π^{-} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +769

A search for time-integrated $C P$ violation in the Cabibbo-suppressed decay $\mbox{$D^0\rightarrowπ^+π^-π^+π^-$}$ is performed using an unbinned, model-independent technique known…

Search for violations of Lorentz invariance and $C P T$ symmetry in $B_{(s)}^{0}$ mixing

LHCb collaboration, R. Aaij, C. Abellán Beteta +729

Violations of $C P T$ symmetry and Lorentz invariance are searched for by studying interference effects in $B^{0}$ mixing and in $B_{s}^{0}$ mixing. Samples of $ B^0\to J/ψK^0_{\mathrm{…
