Beauty production in pp collisions at $\sqrt{s}$ = 2.76 TeV measured via semi-electronic decays / ALICE Collaboration
The ALICE collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity $|y|<0.8$ and transverse momentum $1<p_{\mathrm{T}}<10$ GeV/$c$, in pp collisions at $\sqrt{s} = $ 2.76 TeV. Electrons not originating from semi-electronic decay of beauty hadrons are suppressed using the impact parameter of the corresponding tracks. [...]

Measurement of electrons from beauty hadron decays in pp collisions at $\sqrt{s}$ = 7 TeV / ALICE Collaboration
The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pt < 8 Gev/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy $\sqrt{s}$ = 7 TeV using an integrated luminosity of 2.2 nb$^{-1}$. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. [...]

A study of the claim to observe beauty production at the ISR using two Cerenkov counters in series to identify $e^{+-}$ / Basile, M ; Bonvicini, G ; Cara Romeo, G ; Cifarelli, L ; Contin, A ; D'Ali, G ; Di Cesare, P ; Esposito, B ; Giusti, P ; Massam, Thomas et al.
The purpose of this work was to study the claim of the R416 group to be able to observe the production of 'beauty' at the Split-Field Magnet (SFM) facility of the CERN Intersecting Storage rings (ISR). The two basic points of these authors were: (i) by using an improved 'new' version of the reconstruction programs, a factor approximately 9 in efficiency can be achieved with respect to the 'old' SFM reconstruction programs; (ii) with two Cerenkov counters, each 1 m long, and each with a large area of coverage as in the SFM structure, a rejection power of 1.5*10/sup -4/ against charged hadrons can be achieved..

The leading-baryon effect in Lambda /sub b//sup 0/ production in proton-proton interactions at square root s=62 GeV / Basile, M ; Bonvicini, G ; Cesare, P D ; Cifarelli, L ; Contin, A ; D'Ali, G ; Esposito, B ; Giusti, P ; Massam, Thomas ; Nania, R et al.
The measurement of the longitudinal-momentum production distribution of the 'beauty'-flavoured baryon Lambda /sub b//sup 0/, in the reaction pp to e/sup +/+ Lambda /sub b//sup 0/+anything at square root s=62 GeV, shows clear evidence for a leading-baryon effect in Lambda /sub b//sup 0/ production. A comparison with the data on Lambda /sub c //sup +/, Lambda /sub s//sup 0/ and Lambda /sub s//sup 0/ production is also given. [...]

Heavy flavour production cross-sections from fixed target to collider energies / Wöhri, H K ; Lourenço, C
We review the hadro-production data presently available on charm and beauty absolute production cross-sections, collected by experiments at CERN, DESY and Fermilab. After correcting the published values, in particular for the 'time evolution' of the branching ratios, the measurements are compared to LO pQCD calculations performed with Pythia. [...]

Measurement of the open beauty and charm production cross sections in two photon collisions with DELPHI / Da Silva, W (CNRS, Paris, France)
Heavy b and c quark production in gamma gamma collisions has been measured through semileptonic decays with the DELPHI detector at LEP. The 413 p/sup -1/1 data were collected at center-of-mass energies from 189 GeV to 209 GeV. [...]

The LHCb experiment / Nakada, Tatsuya
The LHCb experiment is designed to fully exploit the large number of b hadrons expected at the LHC energy and luminosity. The experiment is equipped with particle identification devices and can efficiently trigger events with different B-meson final states, allowing systematic studies of CP violation and other rare phenomena in the b hadron system with a high precision which could reveal physics beyond the Standard Model..
