Normalization of neutron-proton differential cross sections
The np differential cross section below 350 MeV neutron laboratory energy is studied using the energy-dependent Nijmegen partial-wave analysis PWA93. We analyze in detail three experiments, performed at LAMPF, at TRIUMF, and at the TSL facility in Uppsala. The issue of normalization of np cross sections is discussed, where we distinguish between measured and calculated normalizations. This anal...
متن کاملAngle-dependent normalization of neutron-proton differential cross sections
Systematic errors in the database of np differential cross sections below 350 MeV are studied. By applying angle-dependent normalizations the χ-values of some seriously flawed data sets can be reduced significantly at the expense of a few degrees of freedom. The renormalized data sets can be made statistically acceptable such that they do not have to be discarded any longer in partialwave analy...
متن کاملTotal and differential cross sections and polarization effects in proton-proton elastic scattering at RHIC
The physics program, the setup, and the performance of an experiment to measure elastic scattering of polarized protons at the Relativistic Heavy Ion Collider (RHIC) are described. In the medium t range, diffractive region, with four momenta transferred 0.006 < t < 1.5 (GeV=c), the experiment will address one of the main, unsolved problems in particle and nuclear physics: long-range QCD and con...
متن کاملMeasurement of the differential and double-differential Drell-Yan cross sections in proton-proton collisions at 7 TeV
Measurements of the differential and double-differential Drell–Yan cross sections are presented using an integrated luminosity of 4.5 (4.8) fb−1 in the dimuon (dielectron) channel of proton-proton collision data recorded with the CMS detector at the LHC at √ s = 7 TeV. The measured inclusive cross section in the Z-peak region (60–120 GeV) is σ(``) = 986.4 ± 0.6 (stat.) ± 5.9 (exp. syst.) ± 21.7...
