Short--Range and Tensor Correlations in the 16O(e,e',pn)14N Reaction
No full textThe cross sections for electron-induced two-nucleon knockout reactions are evaluated for the example of the 16O(e,e'pn)14N reaction leading to discrete states in the residual nucleus 14N. These calculations account for
the effects of nucleon-nucleon correlations and include the contributions of two-body meson exchange currents as the pion seagull, pion in flight, and the isobar current contribution. The effects of short-range as well as
tensor correlations are calculated within the framework of the coupled cluster method employing the Argonne V14 potential as a model for a realistic nucleon-nucleon interaction. The relative importance of correlation
effects as compared to the contribution of the meson exchange currents depends on the final state of the residual nucleus. The cross section leading to specific states, such as, e.g., the ground state of 14N, is rather
sensitive to the details of the correlated wave function
High-momentum proton removal from 16 O and the (e,e'p) cross section
No full textThe cross section for the removal of high-momentum protons from 16O is calculated for high missing energies. The admixture of high-momentum nucleons in the 16O ground state is obtained by calculating the single-hole spectral function directly in the finite nucleus with the inclusion of short-range and tensor correlations induced by a realistic meson-exchange interaction. The presence of high-momentum nucleons in the transition to final states in 15N at 60¿100 MeV missing energy is converted to the coincidence cross section for the (e,e¿p) reaction by including the coupling to the electromagnetic probe and the final state interactions of the outgoing proton in the same way as in the standard analysis of the experimental data. Detectable cross sections for the removal of a single proton at these high missing energies are obtained which are considerably larger at higher missing momentum than the corresponding cross sections for the p-wave quasihole transitions. Cross sections for these quasihole transitions are compared with the most recent experimental data available

This measurement uses a narrow-band neutrino beam with an average neutrino energy of 2.7\,GeV, which is of interest to ongoing and future long-baseline neutrino oscillation experiments. The measured flux-averaged cross section is
, consistent with model prediction. This result is the most precise measurement of neutral-current coherent production in the few-GeV neutrino energy region.Document was prepared by the NOvA Collaboration using the resources of the Fermi National Accelerator Laboratory (Fermilab), a U.S. Department of Energy, Office of Science, HEP user facility.

Selectivity of the {16}O(e,e'pp) reaction to discrete final states.
Get PDFResolution of discrete final states in the 16O(e,e'pp)14C reaction may provide an interesting tool to discriminate between contributions from one- and two-body currents in this reaction. This is based on the
observation that the 0+ ground state and first 2+ state of 14C are reached predominantly by the removal of a1S0 pair from 16O in this reaction, whereas other states mostly arise by the removal of a 3P pair. This
theoretical prediction has been supported recently by an analysis of the pair momentum distribution of the experimental data. In this paper we present results of reaction calculations performed in a direct knockout
framework where final-state interaction and one- and two-body currents are included. The two-nucleon overlap integrals are obtained from a calculation of the two-proton spectral function of 16O and include both long-range
and short-range correlations. The kinematics chosen in the calculations is relevant for recent experiments at NIKHEF and Mainz. We find that the knockout of a 3P proton pair is largely due to the two-body Delta current.
The 1S0 pair knockout, on the other hand, is dominated by contributions from the one-body current and therefore sensitive to two-body short-range correlations. This opens up good perspectives for the study of these
correlations in the 16O(e,e'pp) reaction involving the lowest few states in 14C. In particular the longitudinal structure function f 00 , which might be separated with superparallel kinematics, turns out to be quite sensitive
to the NN potential that is adopted in the calculations

Zwaska (NOvA Collaboration).Using the NOvA neutrino detectors, a broad search has been performed for any signal coincident with 28 gravitational wave events detected by the LIGO/Virgo Collaboration between September 2015 and July 2019. For all of these events, NOvA is sensitive to possible arrival of neutrinos and cosmic rays of GeV and higher energies. For five (seven) events in the NOvA Far (Near) Detector, timely public alerts from the LIGO/Virgo Collaboration allowed recording of MeV-scale events. No signal candidates were found.This document was prepared by the NOvA Collaboration using the resources of the Fermi National Accelerator Laboratory (Fermilab), a U.S. Department of Energy, Office of Science, High Energy Physics(HEP) User Facility.

Analyzing a 14-kton detector equivalent exposure of 6.0610 protons-on-target in the NuMI beam at Fermilab, we observe 95 neutral-current candidates at the Far Detector compared with 83.5 \pm 9.7 \mbox{(stat.)} \pm 9.4 \mbox{(syst.)} events predicted assuming mixing only occurs between active neutrino species. No evidence for transitions is found.
