Test baryon antibaryon oscillation in collider experiments
[摘要] Searching for the New Physics (NP) phenomenon beyond Standard Model (SM) is still a main focus in particle physics. Here we propose to search for Λ - oscillation in the decay J/ψ → ΛAA using BES detector. With one-year luminosity at BESIII, we can put a constraint that the Λ - oscillation mass is smaller than 10-15MeV at 90% confidence level, corresponding to the oscillation time of 10-6second around, in case of non-observation of any signals. These measurements should provide very precious informations besides the neutron oscillation experiment. Also it would be the first-time access by experiment for Λ - oscillation.
