Description
Current and future long-baseline oscillation experiments have the
potential to determine how much the lepton sector violates CP symmetry
by studying nu_e appearance in a nu_\mu beam. Intrinsic nu_e
from the beam are the largest background for these measurements, and
nu_e from oscillations are the signal. Differences between the
nu_e and nu_\mu cross-sections are theoretically predicted, but
have not yet been measured. Constraining these differences is critical
to reducing systematic uncertainties in the hunt for CP
violation. This poster presents the first measurement of the nu_e
CC cross-section on carbon for GeV-scale neutrinos, using ND280, the
T2K near detector. Differential cross-sections in electron momentum,
electron angle and Q^2 are presented, along with the total
flux-averaged cross-section.
