Measurement of prompt hadron production ratios in $pp$ collisions at $\sqrt{s}=$ 0.9 and 7 TeV

LHCb collaboration, R. Aaij, C. Abellan Beteta +619

The charged-particle production ratios $\bar{p}/p$, $K^{-}/K^{+}$, ${\pi }^{-}/{\pi }^{+}$, $(p+\bar{p})/({\pi }^{+}+{\pi }^{-})$, $(K^{+}+K^{-})/({\pi }^{+}+{\pi }^{-})$ and $(p+\bar{p})/(K^{+}+K^{-})$ are measured with t…
