Abstract
Absolute neutrino cross section measurements at the GeV scale are ultimately limited by the knowledge of the initial ν flux. In order to evade such limitation and reach the accuracy that is needed for precision oscillation physics (∼ 1%), substantial advances in flux measurement techniques are requested. We discuss here the possibility of instrumenting the decay tunnel to identify large-angle positrons and monitor νe production from K+ → e+νeπ0 decays. This non conventional technique opens up opportunities to measure the νe CC cross section at the per cent level in the energy range of interest for DUNE/HK. We discuss the progress in the simulation of the facility (beamline and instrumentation) and the ongoing R&D.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
