Abstract
Recent results from the ATLAS experiment on production, decays and spectroscopy of heavy flavour hadrons are presented. The latest results on CP-violation in Bs → J/ψϕ, decays are discussed. Measurements of the inclusive and associated charmonium production are also reported. In addition, searches for pentaquarks with hidden charm and recent results on Bc meson production and decays are highlighted.
Highlights
The ATLAS experiment [1] has a very rich heavy flavour research programme focusing on the measurement of production, decays and spectroscopy of heavy flavour hadrons providing opportunity for precise tests of the Quantum Chromodynamics (QCD) calculations
The analysis presented here introduces the measurement of the Bs0 → J/ψφ decay parameters using
The results presented here are based on pp collisions data at 13 TeV accumulated by the ATLAS detector in the period between 2015 and 2018 with integrated luminosity of 139 fb−1 [5]
Summary
The ATLAS experiment [1] has a very rich heavy flavour research programme focusing on the measurement of production, decays and spectroscopy of heavy flavour hadrons providing opportunity for precise tests of the Quantum Chromodynamics (QCD) calculations. This includes a precise measurement of the CP-violation parameters in Bs → J/ψφ decays, an inclusive and associated J/ψ production cross section measurement, a J/ψp resonances measurement in Λ0b → J/ψpK− decays, and a measurement of the relative Bc±/B± production cross section.
