Near Detector Physics session

*Neutrino and AntiNeutrino Flux

Work out a prescription to determine the neutrino and antineutrino flux in LBNE. The prescription involves identifying a set of measurements and attendant systematic errors with goal to deliver:

(a) Absolute Flux of neutrinos and anti-neutrino at the ND
(b) The relative abundance of the four species of neutrinos, NuMu, NuE, anti-NuMu, and Anti-NuE at ND
(c) Predicting the 4-neutrinos spectrum at the FD relative to ND

*Asymmetries in Nu -vs- NuBar

Work out a prescription to determine the systematic asymmetries in neutrino versus anti-neutrino interactions. The prescription involves identifying a set of measurements at ND which will quantify such asymmetries as might affect the CP-Delta measurement. The study will involve:

(a) Determining the energy scales of neutrino and anti-neutrino CC
(b) Kinematics of exclusive channels (QE, Resonance, DIS) affecting neutrinos differently from anti-neutrinos
(c) Flux (the first topic)

*(anti)Neutrino-Nucleus Interactions

The salient topics under this topic will be:

(a) QE, Res, DIS
(b) Non-perturbative and Perturbative QCD
(c) PCAC, CVC

*Constraining Oscillation Backgrounds at FD

In a long-baseline experiment, typically, the FD measures NuE- and antiNuE- appearance, and NuMu-and antiNuMu-disappearance. The dominant backgrounds to these processes come from mesons, produced in the hadronic-jet, mimicking the oscillation signals. The workshop will focus on how to measure the pion/kaon yields in neutral and charged current interactions with such precision as to keep the systematic errors below the statistical errors.

A related background study, relevant to the kaonic decay of proton, in ND is the production of semi-exclusive kaons in neutrino NC.

*Precision Measurements in ND

The workshop proposes to conduct studies on precision measurements at ND. The topics include:

(a) Adler Sum Rule
(b) Nu-Nucleus Interactions
(c) Delta-S
(d) Electroweak Physics

*Search for New Physics

Some participants at the workshop have expressed interest in exploring high-sensitivity searches for new physics such as:

(a) Weakly Interacting Massive Particles, e.g. light dark matter, heavy-neutrino
(b) Tests of Universality: NuMu -vs- NuE
(c) Large Delta-M**2 oscillation
