Abstract
This paper summarises two analyses of minimum bias data collected with the LHCb detector from pp collisions at the LHC. The geometry, tracking and particle identification system of the LHCb experiment provide unique capabilities for this type of study in a kinematic region where QCD models have large uncertainties. Measurements of prompt hadron production ratios and forward energy flow are presented and compared to predictions from MC event generators.

The tracking system is composed of a precision Vertex Locator (VELO) surrounding the interaction region, a dipole magnet and three downstream tracking stations [1]
Summary
The Large Hadron Collider Beauty experiment (LHCb) at CERN is a single-arm forward spectrometer designed for precision measurements of CP violation and rare B meson decays. It allows the study of QCD processes in the forward region. The resolution for primary (secondary) vertices is ∼ 50(100) μm along the beam axis and the momentum resolution for tracks having hits in both the VELO and the tracking stations is around 0.5%. The partial closure of the VELO around the beam resulted in a non uniform detector acceptance around the beam axis and a slightly lower reconstruction efficiency for charged particles, in the high pseudorapidity region. The measurements presented in this paper are the prompt hadron production ratios and the forward energy flow
