The ERC granted ENUBET project aims at developing the technologies to reduce by a factor ∼10 the systematics in neutrino fluxes from conventional beams, allowing measuring the ν e (and ν e ) cross section with a 1% precision, in the region of interest for future oscillation experiments looking for CP violation. This goal is accomplished by monitoring in an instrumented decay tunnel the high angle positron produced in K e3 decays of charged kaons. The Monte Carlo simulation of the positron tagger in realistic conditions and a preliminary event reconstruction chain will be described, together with results on the expected signal selection efficiency.

Abstract

The ERC granted ENUBET project aims at developing the technologies to reduce by a factor ∼10 the systematics in neutrino fluxes from conventional beams, allowing measuring the ν e (and ν e ) cross section with a 1% precision, in the region of interest for future oscillation experiments looking for CP violation. This goal is accomplished by monitoring in an instrumented decay tunnel the high angle positron produced in K e3 decays of charged kaons. The Monte Carlo simulation of the positron tagger in realistic conditions and a preliminary event reconstruction chain will be described, together with results on the expected signal selection efficiency.
