Status of experimental neutrino-nucleus scattering at a few GeV
At the start of this workshop series
• The field was undergoing a phase change… > Bubble chambers had squeezed out final results > NuTeV, NOMAD & CHORUS had just run > Oscillations has just been confirmed in SK > MINOS, K2K, and MiniBooNE were in construction
• Data in the 10s to 100s GeV/c range was becoming exquisite > Fine grained detectors or narrow-band beams made
these the standard bearers for precision neutrino scattering experiments
• Neutrino-oscillation experiments wanted precision at much lower energies > Sparse, mostly low statistics data on the wrong nuclei
NuFact2016 Scattering, Nelson 2
State of the art (Ca. 2011)
• By now… • SPS & TeVatron
experiments had weighed in • Getting detailed results
from MiniBooNE plus results from K2K, SciBar, and SciBooNE > More than a dozens > Starting to get the right nuclei > Can’t fit it all on one plot
anymore… a good thing > Dearth of antineutrino data
starting to be addressed • Data disagree with models

Neutrino event generators
• Neutrino experiments have are few in situ physics handles > MIP/muon, muon decay (Michel) electrons, neutral pions > Only know the incoming neutrino direction accurately
• We rely heavily on full simulations of neutrino interactions to understand: > Signal selection > Background rejection > Energy reconstruction > Near/far extrapolation
• In the US program we most often use GENIE > C. Andreopoulos et al, NIM A, 614, 87 (2010) > MINERvA will use version v2r6p2 as the reference
but sometimes others • A number of final-state generator exist (GIBUU, NuWRO, NEUT…)
> Some are models and some are more general tools with options > Central values for the generators are fits to scattering data and lag generally theoretical
work > Note the recent NuTune2016, Pittsburgh “Data Tensions” workshop & arXiv:1601.05592
• Many more models than generators > Some with fully specified final states > Some only with computed physics distributions > Generators are working to make more of these models available as options
NuFact2016 Scattering, Nelson 4
Goals of the long-baseline program
• Targets > Quadrant of θ23
(most uncertain of the angles) > Hierarchy of neutrino mass spectrum > CP violation in the neutrino sector
• Later two driven by electron appearance measurements at long baselines at few-GeV energies
> Comparisons of neutrino/antineutrino appearance > Understanding background systematic
uncertainties > Oscillation parameters (esp. the quadrant) have
significant impact on parameter measurements • Pushes most systematics to regimes we’ve
never achieved! > Flux, interactions, energy scales, background,
near/far extrapolation… > e.g. Both NOvA and T2K report 11% syst on their
sample backgrounds and 6-7% in signal

be addressed > First double differential distributions
• MINERvA & T2K results rolling in > Dozens of papers > Thinking beyond process
measurement and working to distinguish models

It’s been an exciting year for the neutrino-nuclear scattering …
• A huge collective push by the field on the run up to NuINT2015, Neutrino2016, & NuFact2016 > Many new results from MINERvA & T2K and continuing data collection > Close out of MINOS and ArgoNeuT scattering programs > NOvA’s near detector producing first scattering results > MicroBooNE comes online and shows first physics distributions
• Huge burst of detailed output documented in the 400+ posters at Neutrino2016 > In many ways these were personal highlights of the whole conference –
excellent time for the sorts of detailed questions you never to ask in a large-talk forum
> I am looking forward to the proceedings documentation of all those details
• Makes a 20m discussion of these results nearly impossible! > I apologize in advance for the short shrift that many results will get here > In an effort to make up for this, I put in full citations of modern results in
the backup slides

I will focus on the last year (or so…) but that leaves plenty to talk about!

Flux status… JPARC flux • Hadron production data from the very
successful dedicated NA61/Shine running program
• Painstaking, but beautiful and painstaking • You will hear more about this in a talk later
this week with updates to include more production data than their published (2013) thin-target flux predictions
Fermilab NuMI flux • Hadron production data from legacy
experiments and from NA49 and MIPP > Also an in situ flux program

Low ν flux method
NuFact2016 Scattering, Nelson
• Charged-current scattering with low hadronic recoil energy (ν) is flat as a function of Ev
• Gives a measurement of the flux’s shape
• This is a shape measurement: > Flux is normalized so that the
extracted inclusive cross section matches an external value at high neutrino energy

Flux from ν on electron scattering
• Signal is a single electron moving in beam direction > Purely electro-weak process > Cross section is smaller than nucleus
scattering by ~2000 • Independent in situ flux constraint
> Important proof of principle for future experiments
> Statistically limited in the MINERvA LE sample (~8% error)
> Results are consistent with the a priori flux (~2%) and with the low v flux
• 3 independent methods yield consistent results

• NOMAD, bubble chambers > Used two-track topology with low thresholds > Consistent with RFG (like GENIE’s model) with
MA=1 GeV but prefer a better nuclear model • K2K, MiniBooNE, MINOS, SciBooNE
> Fine-grained scintillator so higher proton tracking threshold
> Look for a muon and low recoil; use muon kinematics for energy
> See a higher rate and different Q2 distributions consistent with a higher MA + low Q2 suppression
• By 2010: becoming clear that this was probably due to an extra unmodeled process well known in electron scattering > 2 particle, 2 hole (2p2h) > Models include MEC & TE

Long-standing problem in νµ CCQE
2-track QE, proton-based reconstruction
• Select events based on 1 PID’d stopping proton & 1 muon
• Reconstruct kinematics quantities using proton angle and energy
• Very sensitive to final state interactions
• Shape-only comparison • In proton kinematic variables,
see relatively good agreement with Relativistic Fermi Gas (RFA) model for QE scattering
• These 2-track QE make a pretty good standard candle

QE with lepton-based kinematics
• Reconstruct the muon > Require not too much energy
beyond a box around the vertex > Relatively insensitive to final
state interactions (only enter via the background estimate)
> POT normalized (new flux) • Disagreement with Fermi Gas

Muon Neutrino CC inclusive w/ low recoil
• Another tactic is not cut on the recoil, but rather to look at the low recoil in an inclusive sample
• Reconstruct energy both & momentum transfer (somewhat analogous to electron scattering techniques)
• Default GENIE model struggles to explain the data

Muon Neutrino CC inclusive w/ low recoil
NuFact2016 Scattering, Nelson 43
• Compute the “available” energy
• Models adding RPA (charge screening nuclear) effect and a 2p2h process (in this case the Valencia model) improves agreement in some regions, but not strong enough to cover the observed rate
• A Bragg peak counting analysis is also compatible with multi-nucleon final states hypothesis

Closing comments • An intense stream of scattering results > There are many interesting WG2 talks at this meeting!
• These results are confronting both prior low-energy data and theoretical models with differential distributions using better detectors and better understood beams > There are discrepancies with these models and prior
data > These new analyzes are being designed to try to
factorize the different categories of model uncertainties • New initiatives are coming online and current
ones are taking deeper looks into their samples • The result is going to be better generators
(models) and much lower systematics for the next generation of oscillation experiments
