"Table 3" of "Measurement of matter-antimatter differences in beauty baryon decays"

2017

For $\Lambda_b^0\to p\pi^-\pi^+\pi^-$ decays, the CP- and P-violating observables, $a^{\hat{T}-odd}_{CP}$ and $a^{\hat{T}-odd}_{P}$, resulting from the fit to the data are listed with their statistical and systematic uncertainties. Each value is obtained through an independent fit to a region of the phase space defined in Scheme A.

"Table 1" of "Measurement of matter-antimatter differences in beauty baryon decays"

2017

Binning scheme A is defined to exploit interference patterns arising from the resonant structure of the decay. Bins 1-4 focus on the region dominated by the $\Delta(1232)^{++}\to p\pi^{+}$. The other eight bins are defined to study regions where $p\pi^{-}$ esonances are present (5-8) on either side of the $\rho(770)^{0}\to\pi^{+}\pi^{-}$ resonances (5-12). Further splitting for $|\Phi|$ lower or greater than $\pi/2$ is done to reduce potential dilution of asymmetries.
