Measurement of CP asymmetries in Λ0b → ph− decays
A search for 𝐶𝑃 violation in Λ0𝑏 →𝑝𝐾− and Λ0𝑏 →𝑝𝜋− decays is presented using the full Run 1 and Run 2 data samples of 𝑝𝑝 collisions collected with the LHCb detector, corresponding to an integrated luminosity of 9 fb−1 at center-of-mass energies of 7, 8, and 13 TeV. For the Run 2 data sample, the...

| 520 | |a A search for violation in Λ0 →− and Λ0 →− decays is presented using the full Run 1 and Run 2 data samples of collisions collected with the LHCb detector, corresponding to an integrated luminosity of 9 fb−1 at center-of-mass energies of 7, 8, and 13 TeV. For the Run 2 data sample, the -violating asymmetries are measured to be − =(−1.4 ±0.7 ±0.4)% and − =(0.4 ±0.9 ±0.4)%, where the first uncertainty is statistical and the second is systematic. Following significant improvements in the evaluation of systematic uncertainties compared to the previous LHCb measurement, the Run 1 dataset is reanalyzed to update the corresponding results. When combining the Run 2 and updated Run 1 measurements, the final results are found to be − =(−1.1 ±0.7 ±0.4)% and − =(0.2 ±0.8 ±0.4)%, constituting the most precise measurements of these asymmetries to date. | ||
