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


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

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.e. MiniBooNE, K2K, SciBar, MINOS & SciBooNE are historical;

ArgoNeuT & MNOS by next year)

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

Low ν flux method


•  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

model seen in total cross section, shape of cross section >  Has model discriminating power >  Favors a 2p2h contribution >  TEM = Transverse Enhancement Model

New this month! S. Dolan, NuFact2016 Working toward C/O cross section ratios

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


PRL 116, 071802 (2016)

Muon Neutrino CC inclusive w/ low recoil


•  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

MINERvA ME Program •  More than 3X POT of LE sample

•  3.5 times more events/POT •  These statistics will allow study of

nuclear effects in exclusive states •  Wider ranges of energies means wider

range of kinematics to discriminate between models

•  We plan to switch to ME antineutrino mode this winter after 12e20 POT


ν mode

Anti-ν mode

Example of increased kinematic coverage in NuMI ME on-axis data

•  Less than 30% of collected data on these plots (>1M event) •  LE data was only able to report out to Q2 ~ 2 GeV2


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
