NuSTEC Training in Neutrino-Nucleus Scattering Physics 2017
Welcome to the NuSTEC school 2017 webpage!
The deadlines for applications have been modified for the NuSTEC School on Neutrino Nucleus Scattering Physics that will be held at Fermilab this 7-15 November 2017. For those needing an hotel or funding support the deadline is 2nd October, otherwise, the deadline is 22nd October. We will consider early admission for those needing a visa or to arrange international air travel once the application is complete. However, financial support decisions will not be available until after the 2 October deadline.
The program will include 33 hours of lectures and 12 hours of recitation encouraging questions and discussion on all of the day’s lectures. The aim of the program is to provide the necessary theoretical background on the physics of electroweak interactions with nucleons and nuclei. It should allow the participants to understand recent developments and to contribute to this field, which has become very important for the future of neutrino physics. Although this training is ideally suited for experimental and theoretical advanced graduate students and young postdocs, senior researchers may find these lectures informative and are welcome to participate.
The application form can be found at the following link. Application for partial financial support grants is contained in the application form as well.
Application Deadlines: For those applicants needing a hotel room and/or applying for financial support the application deadline is 2 October. Otherwise the application deadline is 22 October.
For those applicants needing to obtain a visa or arrange international air travel, prompt application is encouraged. The steps for obtaining the visa invitation letter are contained in the registration form.
A registration fee of $350 for all participants will cover all lunches and coffee breaks as well as general supplies and transportation support. For participants needing a hotel room, we have a local hotel in St. Charles and bus transportation to / from Fermilab will be provided. $750 covers 10 nights in a shared double room (single available for additional fee) as well as breakfast. For those staying in the hotel, NuSTEC offers a limited number of partial support grants. If you would like to apply for this support, please follow the instructions on the application form.
General introduction (1 hour)
Motivation: why neutrino-nucleon/nucleus interaction theory is important for neutrino oscillation experiments.
Introduction to electroweak interactions on the nucleon (3 hours)
Prof. Richard Hill (University of Kentucky and Fermilab)
Electromagnetic interactions; V-A and current-current theories of weak interactions; CVC and PCAC; single-nucleon matrix elements of the electroweak current and associated form factors; parameterizations and sources of experimental information about electromagnetic and weak form factors.
Introduction to neutrino-nucleus scattering (3 hours)
Generalities of electron- and neutrino-nucleus inclusive and semi-inclusive scattering off nuclei. Phenomenological properties of NN interactions. Relativistic Fermi gas model (success and limitations); shell model; relativistic mean field. Elastic scattering and nuclear form factors. Scaling and superscaling.
Strong and electroweak interactions in nuclei (3 hours)
Two- and three-nucleon pion exchange interactions; realistic models of two- and three-nucleon interactions; realistic models of nuclear electroweak currents including two- and many-body terms; short-range structure of nuclei, nuclear correlations, and quasi-elastic scattering.
Approximate methods for nuclei (I) (2 hours)
The factorization of the nuclear cross sections in the impulse approximation. Similarity of nuclear effects in neutrino and electron interactions. Particle and hole spectral functions. Off-shell effects. Realistic estimate of the hole spectral function in the local-density approximation. Final-state interactions. Difficulties of neutrino-energy reconstruction.
Approximate methods for nuclei (II) (2 hours)
Mean field description of the nucleus and beyond : long range correlations, collective excitations and random phase approximation ; interactions at low energy ; short range correlations, meson exchange currents and their influence on genuine quasi-elastic and 2-nucleon knockout neutrino-induced processes.
Ab initio methods for nuclei (2 hours)
From realistic models of nuclear potentials and currents to the nuclear wave-function; Quantum Monte Carlo methods for the structure and electroweak responses of nuclei; Initial- and final-state correlations: the enlightening example of the proton and the nucleon responses; Relativistic effects in a correlated system.
Pion production and other inelastic channels (3 hours)
QCD (chiral symmetry) constraints to pion pion production at threshold. The role of the Delta(1232) resonance in pion photon and electroproduction. Electroweak excitation of baryon resonances. Transition form factors. The Rein-Sehgal model and why it is outdated. Unitarization. Watson theorem. Single pion production, diffractive off a nucleon and coherent off a nucleus. Other meson production channels (kaon, 2 pions, associated strangeness, etc).
Description of exclusive channels and final state interactions (3 hours)
Transport approach to the description of the exclusive final state; GiBUU; hadrons in nuclei: propagation and final state interactions; formation time; baryon resonances in the nuclear medium. Entanglement between quasielastic and inelastic processes.
Inclusive electron and neutrino scattering in the shallow- and deep-inelastic regimes (3 hours)
General analysis of deep inelastic scattering (DIS); Bjorken scaling; quark-parton model; DGLAP equations; nuclear effects in DIS; shadowing; extraction of parton distribution functions; duality. Shallow inelastic scattering.
Systematics in neutrino oscillation experiments (3 hours)
Very brief recap of T2K and NOVA detectors and description of the oscillation analyses in the two experiments. Then we will try to answer to the following questions:
-how the uncertainties on neutrino-nucleus scattering enter in the oscillation game?
-how can we test the sensitivity of our analyses to such uncertainties?
-what do we need to measure to improve the cross-section systematics in the determination of the oscillation parameters?
And, if time permits, we will make a short excursion into the future: what will be the
impact of such systematics in DUNE and HyperKamiokande?
12.1. Monte Carlo methods and event generators (3 hours)
The lectures start with an introduction to Monte Carlo (MC) methods, followed by an example of their usage in the case of quasielastic neutrino scattering off nucleon. The second part is devoted to the description of the models commonly used in MC neutrino event generators. Finally, practical examples of running GENIE and NuWro are presented.
12.2. Nuisance (2 hours)
First we shall describe the experimental methods used to extract neutrino cross-sections and their limitations. The NUISANCE generator tuning framework will then be introduced through practical examples, comparing multiple generators to a single dataset, before using a simple likelihood fit to tune a free model parameter in one of the generators of choice. A virtual box containing the necessary software will be provided beforehand.
