Abstract
SHIP is a new general purpose fixed target facility, proposed at the CERN SPS accelerator. In its initial phase the 400GeV proton beam will be dumped on a heavy target with the aim of integrating 2 10 20 pot in 5 years. A detector downstream of the target will allow to search long-lived exotic particles with masses below O(10) GeV/c 2 forseen in extension of the Standard Model. Another dedicated detector, that will be the focus of this talk, will allow to study active neutrino crosssections and angular distributions. The neutrino detector consists of an emulsion target, based on the Emulsion Cloud Chamber technology fruitfully employed in the OPERA experiment. The Emulsion Cloud Chamber will be placed in a magnetic field, with the so-called Compact Emulsion spectrometer, a few cm thick chamber for the charge and momentum measurement of hadrons. This will provide the leptonic number measurement also in the hadronic tau decay channels. The detector will be hybrid, using nuclear emulsions and electronic detectors for the time stamp of the events and the measurement of the muon momentum. The muon system will also be based on the design of the one used in the OPERA experiment.
Highlights
The 2012 was the year of the success of the Standard Model (SM)
There are still some phenomena that the SM is unable to explain: the existence of dark matter (DM) and its nature, the baryonic asymmetry of the Universe and neutrino masses. They all hint at the existence of new physics and of particles either too heavy or too weakly interacting to be detected but that could represent the key to work out a solution to the previous listed issues
A physics program focusing on very weakly couplings— complementary to that of LHC— might on the other hand be supplied by a beam dump facility
Summary
The 2012 was the year of the success of the Standard Model (SM). the discovery of the Higgs boson [1],[2] was a milestone in the field of Particle Physics. There are still some phenomena that the SM is unable to explain: the existence of dark matter (DM) and its nature, the baryonic asymmetry of the Universe and neutrino masses They all hint at the existence of new physics and of particles either too heavy or too weakly interacting to be detected but that could represent the key to work out a solution to the previous listed issues. A physics program focusing on very weakly couplings— complementary to that of LHC— might on the other hand be supplied by a beam dump facility. It is in this framework that the SHiP experiment (Search for Hidden Particles, [4], [5]) sets. It will host a neutrino detector to discover the tau anti-neutrino and to study tau neutrino and anti-neutrino cross-sections
