Sažetak (engleski)
A new, more precise measurement of the Λ hyperon lifetime is performed using a large data sample of Pb–Pb collisions at √𝑠NN=5.02  TeV with ALICE. The Λ and ¯Λ hyperons are reconstructed at midrapidity using their two-body weak decay channel Λ→p+𝜋− and ¯Λ→¯p+𝜋+. The measured value of the Λ lifetime is 𝜏Λ=[261.07±0.37(stat.)±0.72(syst.)]  ps. The relative difference between the lifetime of Λ and ¯Λ, which represents an important test of 𝐶⁢𝑃⁢𝑇 invariance in the strangeness sector, is also measured. The obtained value (𝜏Λ−𝜏¯Λ)/𝜏Λ=0.0013±0.0028⁢(stat.)±0.0021⁢(syst.) is consistent with zero within the uncertainties. Both measurements of the Λ hyperon lifetime and of the relative difference between 𝜏Λ and 𝜏¯Λ are in agreement with the corresponding world averages of the Particle Data Group and about a factor of three more precise.
