Title: Hadronic Interaction Modelling in MINOS

Abstract

The Main Injector Neutrino Oscillation search (MINOS) uses two detectors separated by 735 km to measure a beam of neutrinos created by the Neutrinos at the Main Injector (NuMI) facility at Fermi National Accelerator Laboratory. The experiment has recently reported an observation of {nu}{mu} disappearance consistent with neutrino oscillations. We describe the manner in which the experiment's results depend on the correct understanding and modeling of hadronic systems.

  • We discuss about effects of the non-standard interaction of neutrinos with matter on the {nu}{sub e} appearance search in the MINOS experiment. We consider the effects of the complex phase of the interaction and of the uncertainty on {theta}{sub 23} also. We show that the oscillation probability can be so large that can not be explained by the ordinary oscillation. We show also how much constraints on the non-standard effects can be improved if the experiment does not observe {nu}{sub e} appearance signal.

  • A classical Poincare invariant particle dynamics is formulated in the framework of constraint Hamiltonian systems. This canonical formalism is compatible with physical requirements like world line invariance, cluster separability, causality principles, and a reasonable non-relativistic limit. In a microscopic phase space approach the classical propagation based on constraint dynamics is combined with some quantum effects like multiple two-body elastic and inelastic scattering to serve as a model for multi-hadronic interactions. This model which is dubbed relativistic quantum molecular dynamics'' is used to study relativistic nucleus--nucleus collisions. The results demonstrate the importance of collective motion, nuclear stopping, and secondary scattering. Itmore » is discussed whether global properties of hot, dense hadronic and quark matter---the equation of state and, in particular, the phase transition to a quark gluon plasma---can be probed in heavy ion collisions. {copyright} 1989 Academic Press, Inc.« less
  • A search for mixing between active neutrinos and light sterile neutrinos has been performed by looking for muon neutrino disappearance in two detectors at baselines of 1.04 km and 735 km, using a combined MINOS and MINOS+ exposure ofmore » $$16.36\times10^{20}$$ protons-on-target. A simultaneous fit to the charged-current muon neutrino and neutral-current neutrino energy spectra in the two detectors yields no evidence for sterile neutrino mixing using a 3+1 model. The most stringent limit to date is set on the mixing parameter $$\sin^2\theta_{24}$$ for most values of the sterile neutrino mass-splitting $$\Delta m^2_{41} > 10^{-4}$$ eV$^2$.« less
