However, more recent results at LHCb in 2011, 2012, and 2021 with larger data samples have demonstrated no significant deviation from the Standard Model prediction of very nearly zero asymmetry.
Despite earlier results, newer data from LHCb experiments conducted in 2011, 2012, and 2021, which involved larger sample sizes, have not revealed any substantial discrepancies with the Standard Model's prediction for near-zero asymmetry.
