“…In these models also heavy quark EDMs can set powerful constraints [11], hence the direct search for EDMs of heavy baryons are especially motivated and experimental ideas are called for. On the theory side, the description of charm and bottom baryon EDMs is being developed within the framework of baryon chiral perturbation theory [12,13], while input from lattice QCD is still necessary for the interpretation of the measurement in terms of quark effective operators.…”

The electric and magnetic dipole moment of charm and bottom baryons can be measured for the first time by using bent crystal technology at the LHC. The experimental method, proposed in recent years, suffers from limited statistics, which dominates the uncertainty of the measurement. In this work, we present an alternative experimental layout, based on the use of crystal lenses, that improves the trapping efficiency by about a factor 15 (35) for a 2-cm (5-mm) target with respect to the nominal layout, with plain crystal faces. The efficiencies are evaluated taking into account the constraints from the LHC machine, and the technical challenges to realize this novel experimental method are discussed.
