LHCb fixed target p cross section in pHe data Heavy flavour in pAr data Conclusion LHCb fixed target p cross section in pHe data Heavy flavour in pAr data Conclusion LHCb detector and the fixed-target system LHCb was designed for heavy flavor physics but is now a general purpose detector Fully instrumented in 2 < y < 5 Excellent performance: Vertex, IP and decay time resolution Momentum resolution Particle identification K K 95%, K 5% 97%, 1-3% Unique capability at LHC: Injecting noble gas (He, Ne, Ar) in the Vertex Locator Primary role: beam-gas imaging for luminosity measurement Can be used as an internal gas target ( 10 -7 mbar) Allows measurement of p-gas and ion-gas interactions Access to the kinematic region: s NN [69, 115] GeV and backward rapidity E.
