• Аннотация: 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 the LHCb detector using $0.3 {\rm nb^{-1}}$ of $pp$ collisions delivered by the LHC at $\sqrt{s} = 0.9$ TeV and $1.8 {\rm nb^{-1}}$ at $\sqrt{s} = 7$ TeV. The measurements are performed as a function of transverse momentum $p_{\rm T}$ and pseudorapidity $\eta$. The production ratios are compared to the predictions of several Monte Carlo generator settings, none of which are able to describe adequately all observables. The ratio $\bar{p}/p$ is also considered as a function of rapidity loss, $\Delta y \equiv y_{\rm beam} - y$, and is used to constrain models of baryon transport.

 [1] Measurement of prompt hadron production ratios in pp collisions at = 0.9 and 7 tev / C. LHCb, Н. В. Никитин, А. К. Лефлат et al. // European Physical Journal C. — 2012. — Vol. 72. — P. 2168. The charged-particle production ratios {p}/p, K-/K+, π-/π+, (p + {p})/(π+ + π-), (K+ + K-)/(π+ + π-) and (p + {p})/(K+ + K-) are measured with the LHCb detector using 0.3 {nb{-1}} of pp collisions delivered by the LHC at √({s} = 0.9 TeV and 1.8 { nb{-1}} at √({s} = 7 TeV. The measurements are performed as a function of transverse momentum p_{T} and pseudorapidity η. The production ratios are compared to the predictions of several Monte Carlo generator settings, none of which are able to describe adequately all observables. The ratio {p}/p is also considered as a function of rapidity loss, Δy ≡y_{ beam} - y, and is used to constrain models of baryon transport.))
