“…It constrains in particular the (valence) quark densities, as the gluon density enters only at next-to-leading order (NLO) and can thus only be determined from scaling violations. The decomposition of the light quark flavors can then be constrained by neutrino structure function data [12,13], and the strange quark density derived from dimuon production in neutrino DIS [14,15], while the charm structure function F c 2 , and to a lesser extent F b 2 for the bottom quark, are directly accessible at HERA [16][17][18][19][20][21][22].…”

Parton densities from LHC vector boson production at small and large transverse momenta

The parton densities of the proton are of fundamental importance not only for our description of hadronic and nuclear structure, but also for reliable predictions for new heavy-particle searches at colliders. At the large partonic momentum fractions required for the production of these particles, the parton distribution functions-in particular, that of the gluon-are unfortunately still badly constrained. In this paper, we investigate the possibility to improve on their determination with new data coming from electroweak vector boson production at large transverse momenta at the LHC with center-of-mass energies of 7, 8, or 14 TeV. We demonstrate that this process is dominated by quark-gluon scattering, that theoretical predictions can be reliably made on the basis of next-to-leading order perturbation theory and its resummation, and that these data should thus be used in global fits. We also point out that the nonperturbative parameters determined from Tevatron Run 1 Z-boson

“…The resulting cross sections are consistent to better than 1% in every bin, which verifies that the extracted cross sections are insensitive to the initially assumed simulated fluxes. Figure 6 compares the measured isoscalar-corrected charged-current inclusive ν μ cross section to the MINOS [17], T2K [52][53][54], CCFR [15], Argoneut [55,56] IHEP-JINR [57], NOMAD [10], NuTeV [16], CDHS [58], and IHEP-ITEP [59] measurements. Not shown are the Gargamelle [60] and SciBooNE [6] results, which reported less precise neutrino cross sections within the plotted energy range.…”

“…The results of this analysis agree with the NOMAD and MINOS results within uncertainties, but extend to lower energies. Figure 6 also compares the measured isoscalar-corrected charged-currentν μ inclusive cross section to the MINOS [17], IHEP-ITEP [59], and IHEP-JINR [57], CCFR [15], Argoneut [55,56], NuTeV [16], and CDHS [58] measurements.

Measurements of the inclusive neutrino and antineutrino charged current cross sections in MINERvA using the low- ν flux method

The total cross sections are important ingredients for the current and future neutrino oscillation experiments. We present measurements of the total charged-current neutrino and antineutrino cross sections on scintillator (CH) in the NuMI low-energy beamline using an in situ prediction of the shape of the flux as a function of neutrino energy from 2-50 GeV. This flux prediction takes advantage of the fact that neutrino and antineutrino interactions with low nuclear recoil energy (ν) have a nearly constant cross section as a function of incident neutrino energy. This measurement is the lowest energy application of the low-ν flux technique, the first time it has been used in the NuMI antineutrino beam configuration, and demonstrates that the technique is applicable to future neutrino beams operating at multi-GeV energies. The cross section measurements presented are the most precise measurements to date below 5 GeV.
