1 Status of experimental neutrino-nucleus scattering at a few GeV Jeff Nelson William & Mary NuFact2016 Quy Nhon, Vietnam August 23nd, 2016

2 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

3 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 J.A.Formaggio, G.P.Zeller, Rev.Mod.Phys. 84 (2012) 1307 NuFact2016 Scattering, Nelson 3

4 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: 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 θ 23 (most uncertain of the angles) > Hierarchy of neutrino mass spectrum > CP violation in the neutrino sector Later two driven by electron

5 Goals of the long-baseline program Targets > Quadrant of θ 23 (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 DUNE CDR, Fig 3.23 (2015) NuFact2016 Scattering, Nelson 5

6 State of scattering (ca. 2015) Final results from MINOS and ArgoNeut > Down E v ~ few GeV Final results from MiniBooNE, K2K, and SciBooNE > All these are for E v < ~1 GeV > Dearth of antineutrino data starting to be addressed > First double differential distributions MINERvA & T2K results rolling in > Dozens of papers > Thinking beyond process measurement and working to distinguish models NOvA & MicroBooNE are on the cusp! cm 2 / GeV) -38 cm 2 / GeV) ν cross section / E ν (10-38 ν cross section / E ν ( QE QE TOTAL RES DIS RES Updated last winter DIS A.

8 It s been an exciting year for the neutrinonuclear 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 NuFact2016 Scattering, Nelson 8
