“…The uncertainties on the neutrino interaction and FSI models affect dσ/dQ 2 QE,p through the efficiency correction and are dominated by uncertainties on the resonance production axial mass parameter, pion absorption, and pion inelastic scattering. The uncertainties associated with hadron propagation through MINERvA are evaluated by shifting the pion and proton total inelastic cross sections by 10%, an uncertainty derived from external hadron production data [42][43][44][45]. This uncertainty affects proton tracking and PID efficiencies and acceptance for Q 2 QE,p > 0.8 GeV 2 .…”

A study of charged-current muon neutrino scattering on hydrocarbon in which the final state includes a muon, at least one proton, and no pions is presented. Although this signature has the topology of neutrino quasielastic scattering from neutrons, the event sample contains contributions from quasielastic and inelastic processes where pions are absorbed in the nucleus. The analysis accepts events with muon production angles up to 70 • and proton kinetic energies greater than 110 MeV. The cross section, when based completely on hadronic kinematics, is well-described by a relativistic Fermi gas nuclear model including the neutrino event generator modeling for inelastic processes and particle transportation through the nucleus. This is in contrast to the quasielastic cross section based on muon kinematics, which is best described by an extended model that incorporates multinucleon correlations. This measurement guides the formulation of a complete description of neutrino-nucleus interactions that encompasses the hadronic as well as the leptonic aspects of this process.

“…(1.4) in the A resonance region (0.2-0.4GeV/c). Reaction cross sections of n on Pb and other nuclei down to Carbon have been measured at beam momenta between 0.71 and 2.00 GeV/c [5]. We shall see in the next section that they agree with a slightly refined version of Eq.…”

“…(1.4), provided one takes for R the uniform sphere radius (which is natural for geometrical models). The agreement is in fact better than for the much more complicated multiple scattering models [5]! However, the model fails definitely on the lowenergy side of the A-resonance, and for lighter nuclei also on the high-energy side (0.4-0.9 GeV/c).…”

Abstract. The slowing down of hadrons in a moderator entails an intensity loss by nuclear absorption. The loss is expected to be particularly large for negative hadrons, due to a combination of Coulomb attraction and strong local absorption. A black sphere absorption model is set up and used for numerical calculations of absorption probability per momentum loss. For K-and ~ on heavy nuclei, a sharp maximum is found for kinetic energies below 0.1 MeV.

2011Elucidating the nature of neutrino oscillation continues to be a goal in the vanguard of the efforts of physics experiment. As neutrino oscillation searches seek an increasingly elusive signal, a thorough understanding of the possible backgrounds becomes ever more important.Measurements of neutrino-nucleus interaction cross sections are key to this understanding. Searches for ν μ → ν e oscillation-a channel that may yield insight into the vanishingly small mixing parameter θ 13 , CP violation, and the neutrino mass hierarchy-are particularly susceptible to contamination from neutral current single π 0 (NC 1π 0 ) production. Unfortunately, the available data concerning NC 1π 0 production are limited in scope and statistics.Without satisfactory constraints, theoretical models of NC 1π 0 production yield substantially differing predictions in the critical E ν ∼ 1 GeV regime. Additional investigation of this interaction can ameliorate the current de ciencies.e Mini Booster Neutrino Experiment (MiniBooNE) is a short-baseline neutrino oscillation search operating at the Fermi National Accelerator Laboratory (Fermilab). While the oscillation search is the principal charge of the MiniBooNE collaboration, the extensive data (∼ 10 6 neutrino events) offer a rich resource with which to conduct neutrino cross section measurements. is work concerns the measurement of both neutrino and antineutrino NC 1π 0 production cross sections at MiniBooNE. e size of the event samples used in the analysis exceeds that of all other similar experiments combined by an order of magnitude. We present the rst measurements of the absolute NC 1π 0 cross section as well as the rst differential cross sections in both neutrino and antineutrino mode. Speci cally, we measure single differential cross sections with respect to pion momentum and pion angle. We nd the ux-averaged, total cross sections for NC 1π 0 production on CH 2 to be AcknowledgementsImagine my dismay at learning that I did not become the kind of doctor that can order people to take off their pants. Awkward! I must have checked the wrong box on the form.Regardless, it would impolitic of me to fail to acknowledge those I worked (and played) with on my way to becoming a Doctor of Philosophy. e process has been occasionally tedious and quite oen challenging but generally fascinating and always enjoyable. Mathematica, I speak to you as a person because no soware could possibly be so ckle.I liken you to television' s Dr. Gregory House: abrasive and uncooperative to a fault, but always producing beautiful results. I invested countless hours in bending you to my will.Sometimes you would crash in protest and I would lose the day' s work. Well played, Mathematica! Well played, indeed. Aer much struggling, I was able to reliably produce gures in Mathematica, and very oen I would receive compliments for those gures. All told, the ends did justify the means.I am profoundly grateful to the friends in New Haven who provided much needed diversions: Tom, Ethan, Jerry, Kevin, Will, Peter...
