Figure 1: Region in the (x, Q^{2} ) plane accessible to LHCb (adapted from Ref. [7]). | |
Figure 2: Some illustrative events reconstructed in LHCb where the leading jet has p_{T}^{jet} >10 GeV/c from very early runs at 7 TeV. One of the runs on which we have tested the selection criteria. Jets reconstruction has been done with the k_{T} algorithm in the E-recombination scheme with R = 1 and p_{T}^{cut} = 1 GeV/c. As “Underlying Event” (yellow) we classify any particle non clustered in the two jets with higher momentum, while “noise” is any track with χ^{2} /dof ≥ 10. | |
Figure 3: Normalized differential raw transverse energy distribution compared with that obtained applying the k_{T} algorithm to particles simulated with the LHCb Monte Carlo program (see text). | |
Figure 4: Distribution of the azimuthal angle difference ∆φ = φ_{jet1} − φ_{jet2} for the two leading jets in all events that have at least two jets with p_{T} > 20 GeV/c. The peak at ∆φ ≈ π is evident. The full line is the result of the fit of the data with the sum of a polynomial background (dashed line) and a Gaussian function. | |
Figure 5: Differential distribution of the asymmetry parameter A, defined by Eq. (2), for the events in which the two jets have |∆φ − π |< 40◦. | |
Figure 6: Invariant mass distribution for jet pairs with p_{T 1} and p_{T 2} ≥ 20 GeV/c, |∆φ − π |≤ 40◦ and A ≤ 0.2. The dashed histogram shows the LHCb-MC (see text) simulated distribution. | |
Figure 7: Range in (x ̃, Q ̃^{2} ), defined in the text, that could be experimentally accessible to LHCb through the measurement of dijets at √s = 7 TeV. | |
Figure 8: Dijet x ̃ distribution for various Q ̃^{2} ranges. |
