Description:
This article presents differential measurements of the asymmetry between $$ {varLambda}_b^0 $$ Λ b 0 and $$ {overline{varLambda}}_b^0 $$ Λ ¯ b 0 baryon production rates in proton-proton collisions at centre-of-mass energies of $$ sqrt{s} $$ s = 7 and 8 TeV collected with the LHCb experiment, corresponding to an integrated luminosity of 3 fb−1. The $$ {varLambda}_b^0 $$ Λ b 0 baryons are reconstructed through the inclusive semileptonic decay $$ {varLambda}_b^0 $$ Λ b 0 → $$ {varLambda}_c^{+} $$ Λ c + μ−$$ overline{
u} $$ ν ¯ μX. The production asymmetry is measured both in intervals of rapidity in the range 2.15 〈 y
