Measurement of ${\rm Y}$ production in $pp$ collisions at $\sqrt{s}$= 13 TeV

LHCb collaboration, R. Aaij, B. Adeva +782

The production cross-sections of ${\rm Y}(1S)$, ${\rm Y}(2S)$ and ${\rm Y}(3S)$ mesons in proton-proton collisions at $\sqrt{s}$= 13 TeV are measured with a data sample corresponding to an integrate…
