LHCb detector boosts precision of muon asymmetry measurement

Using 5.1 inverse femtobarns of data collected between 2016 and 2018, the LHCb collaboration reports the most precise measurement to date of the muon charge asymmetry stemming from W boson decays. Researchers focused on muons with transverse momentum between 25 and 55 GeV and pseudorapidity between 2.0 and 4.5 to refine this analysis of particle behavior. This result exhibits excellent agreement with predictions using next-to-next-to-leading-order perturbative quantum chromodynamics, further validating complex theoretical models of particle physics. LHCb Detector Measures Muon Charge Asymmetry in 13 TeV p p Collisions 5.1 inverse femtobarns of data were collected over a three-year period. This focused range allowed for a detailed examination of particle behavior within specific parameters, refining previous understandings of muon interactions. Researchers corrected for experimental factors including efficiencies, resolution, and final-state photon radiation to achieve this level of accuracy. This confirmation strengthens the Standard Model’s predictive power in the high-energy realm. The findings, published in Physical Review Letters, are openly accessible with a Gold Open Access status and associated datasets available through ePIC handles.
