Tesis doctoral de José Luis Alcaraz Aunion
This thesis presents the measurement of the charged current quasi-elastic (ccqe) neutrino-nucleon cross section at neutrino energies around 1 gev. This measurement has two main physical motivations. On one hand, the neutrino-nucleon interactions at few gev is a region where existing old data are sparse and with low statistics. The current measurement populates low energy regions with higher statistics and precision than previous experiments. on the other hand, the ccqe interaction is the most useful interaction in neutrino oscillation experiments. The ccqe channel is used to measure the initial and final neutrino fluxes in order to determine the neutrino fraction that disappeared. the neutrino oscillation experiments work at low neutrino energies, so precise measurement of ccqe interactions are essential for flux measurements. the main goal of this thesis is to measure the ccqe absolute neutrino cross section from the sciboone data. the scibar booster neutrino experiment (sciboone) is a neutrino and anti-neutrino scattering off experiment. The neutrino energy spectrum works at energies around 1 gev. Sciboone was running from june 8th 2007 to august 18th 2008. In that period, the experiment collected a total of 2.65e20 protons on target (pot). This thesis has used full data collection in neutrino mode 0.99e20 pot. a ccqe selection cut has been performed, achieving around 70% pure ccqe sample. A fit method has been exclusively developed to determine the absolute ccqe cross section, presenting results in a neutrino energy range from 0.2 to 2 gev. The results are compatible with the neut predictions. The sciboone measurement has been compared with both carbon (miniboone) and deuterium (anl and bnl) target experiments, showing a good agreement in both cases.
