Search for Hidden Particles

From Wikipedia, the free encyclopedia

The Search for Hidden Particle (SHiP) is a proposed fixed-target experiment at CERN's Super Proton Synchrotron (SPS) with the goal of searching for the interactions and measurements of the weakly interacting particles. In October 2013, the Expression of Interest letter for SHiP was submitted to the SPS Council (SPSC). Following which the Technical Proposal was submitted in April 2015, describing the experimental and detector facility. The Comprehensive Design Study was completed during 2016-19.[1][2][3] The experiment is planned to begin in 2027, and begin collecting data in 2030.[4]

SHiP Collaboration intends to search for the weakly interacting particles whose masses are below the Fermi energy scale. Such particles cannot be detected at Large Hadron Collider yet, though the High Luminosity LHC may open some possibilities. Alongside, the SHiP detector will also search for weakly-interacting sub-GeV dark matter particles.[1][5][6][7]

SHiP also plans to add information to the domain of tau neutrino physics. Out of the three neutrino flavors, the tau neutrino is the least studied. The experiment will aim to make the first direct observation of anti-tau neutrino, as well as measurements of the tau-neutrino and anti-tau neutrino cross-sections.[8][9] Another goal is to study lepton flavor non-conservation, by observing the decays of the tau-leptons.[10][1]
