The violation of Baryon Number, $\mathcal{B}$, is an essential ingredient for the preferential creation matter over antimatter needed to account observed baryon asymmetry in universe. However, such a process has yet be experimentally observed. HIBEAM/NNBAR %experiment program proposed two-stage experiment at European Spallation Source (ESS) search number violation. will include high-sensitivity searches processes that violate by one or two units: free neutron-antineutron oscillation...

We consider a possible neutron–antineutron (n−n¯) oscillation experiment at the PF1B instrument Institut Laue Langevin. It can improve best existing constraint on transition rate and also allow testing of methods instrumentation which would be needed for later larger-scale ESS. The main gain factors over most competitive experiment, performed earlier PF1 ILL, are: more intense neutron beam new operating mode based coherent n n¯ mirror reflections. installation such an need temporary...
